Details on this season's biggest finales

The 100 (The CW)

Airs: Wednesday, May 24 at 9/8c

The 100's fourth season finale is set to be the most heart-pounding yet as Clarke (Eliza Taylor) and the people of Earth must find a way to survive before the radiation wave hits. In crafting this season, creator Jason Rothenberg says his goal was to create a story in which the clock starts ticking in the premiere and never stops until the finale, which "unfolds is something almost close to real time," he explains. "It's like, '42 minutes and 8 seconds to the deathwave landing in our world and killing everybody.' And so it really feels breathless."

Fans can also expect the long-simmering storylines surrounding the Flame, the Second Dawn and Nightblood to be paid off by the time this season comes to a close. "There's a pretty powerful artificial intelligence in [the Flame] that might be helpful, and there are Nightbloods among us now," teases Rothenberg.

While the impending nuclear radiation means this finale will be the deadliest one ever in terms of the sheer number of people killed, Rothenberg refuses to say whether it will also be the deadliest finale for our main characters. He did, however, promise that this season won't end with another deus ex machina featuring Clark pulling a lever or pressing a button that conveniently saves the day at the last minute.

"It's a very different finale for sure," Rothenberg says. "Clarke's story in the finale is very different than what we've seen from her before. She's definitely being forced to rely on her friends more than she has in the past and accept that she can't do it all on her own. I won't say whether there's a level pulled or a button pushed -- there probably is in various ways -- but it's not quite as 'it all comes down to pulling a lever' as it has in the past."

Arrow (The CW)

Airs: Wednesday, May 24 at 8/7c

Going into the finale's epic showdown between the Green Arrow and Prometheus, Adrian Chase (Josh Segarra) will remain several steps ahead of Oliver (Stephen Amell), which will only make it harder for Team Arrow to defeat him. "True to his word, Chase is going to force Oliver to face his violent past and answer the question once and for all: is he a killer or a hero?" executive producer Wendy Mericle says. "To prove he's the hero, Oliver will be forced to let go of his past, the one his father burdened him with in the pilot, and look forward to a new future and a new legacy."

As Oliver tries to begin a new chapter of his life, Arrow will close a chapter: the finale will (thankfully) mark the end of the flashbacks. "The episode is going to end with a bang, and in the process, we're finally going to see how Oliver planned his escape from Lian Yu in the unseen moments leading up to Oliver's introduction in the pilot," Mericle explains. "As Oliver leaves Lian Yu in the flashbacks, he will also be saying goodbye to Lian Yu in the present day story."

Both Manu Bennett and Katrina Law will reprise their roles as Slade Wilson and Nyssa al Ghul, respectively. When she reappears in Star City, Nyssa will go head-to-head with her sister Talia, who trained Chase to become Prometheus to avenge her father's death at Oliver's hand. Katie Cassidy will also return in the finale as Black Siren, a role she will continue in Season 6 as a series regular.

The Big Bang Theory (CBS)

Airs: Thursday, May 11 at 8/7c

Dr. Ramona Nowitzki (Riki Lindhome) returns for the first time since Season 2 in The Big Bang Theory's tenth season finale. Back then, she was just a graduate student with a huge crush on Sheldon (Jim Parsons). Now she's popping back up in Sheldon's life while Amy (Mayim Bialik) is away at Princeton, much to the concern of Sheldon's friends. (Fun fact: Riki Lindhome's musical partner in the group Garfunkel & Oates, Kate Micucci, plays Raj's ex Lucy).

Black-ish (ABC)

Airs: Wednesday, May 10 at 9:30/8:30c

Black-ish will take a turn toward the dramatic as it wraps its third season. In the finale, which is directed by Eva Longoria, Dre (Anthony Anderson) is planning the best baby shower for Bow (Tracee Ellis Ross), but when she visits her OB/GYN with a headache, she finds out there are complications. Like many storylines on Black-ish, this one is also inspired by creator Kenya Barris' real life; last year, his wife Bow Barris gave birth to their sixth child prematurely after she was diagnosed with preeclampsia, a rare pregnancy complication. "At the table read, I remember crying because I was moved in a way I wasn't expecting to be moved because of how it affected my life," Barris says. (Bow and the baby are both healthy now.)

The Blacklist (NBC)

Airs: Thursday, May 18 at 9/8c (two hours)

The final two episodes of The Blacklist will concentrate mostly on the face-off between Red (James Spader) and his onetime confidant, Mr. Kaplan (Susan Blommaert). And there's a good chance this will be a fight to the death. "She's so hell-bent on destroying him," creator Jon Bokenkamp tells TVGuide.com. "It's absolutely going to be a showdown, and it's going to be a really fun showdown at that." And if Red goes down, it's likely that he'll take some members of the FBI with him. "One of the unintended consequences of Kaplan targeting Reddington is potentially our task force," Bokenkamp says. "They really do find themselves potentially caught in a web that is very difficult to extract from."

Blindspot (NBC)

Airs: Wednesday, May 17 at 8/7c

Blindspot has made good on its promise to deliver answers for its myriad questions in Season 2, and that will continue right through the finale. But that's not all. #Jeller fans, rejoice! "Not only are you going to get some amazing character moments between Kurt (Sullivan Stapleton) and Jane (Jaimie Alexander), but most of your major mythology questions you've had since Season 1 will be answered," creator Martin Gero tells TVGuide.com. And if you thought the show's recent trip to shoot on location in Thailand was big, Gero says the finale will be even bigger. "This last episode is the biggest we've ever done, both in scope and mythology. It barely contains itself within the 43 minutes of allotted time." You can also expect to finally see Sandstorm's Phase 2, Roman (Luke Mitchell) play a huge part in the action and more details on Jane's tattoos. But will we see more Nas (Archi Panjabi) after she took the fall for the disastrous FBI raid? "Uhhh, maybe?" He can't give it all away.

Bull (CBS)

Airs: Tuesday, May 23 at 9/8c

Bull's gotta have Faith! Buffy the Vampire Slayer's Eliza Dushku begins a three-episode stint on May 9 as hot-shot criminal attorney J.P. Nunnelly, who agrees to defend Benny (Freddy Rodriguez) against charges of misconduct in exchange for Bull (Michael Weatherly) acting as a consultant on three of her cases. In the finale, they all head to Miami to tackle a drug trafficking case. If all goes well (or maybe even if it doesn't), Dushku could be sticking around for much longer: She has an option to be upped to a series regular next season.

Chicago Fire (NBC)

Airs: TBA

"It's going to be another gigantic one," executive producer Derek Haas teases about the call that dominates the Season 5 finale. "We thought it would be interesting to finish with a giant fire and remind everyone why the show's called Chicago Fire." The blaze in question brings everyone from 51 out to the scene -- but not all of them may be coming back alive. A cliffhanger ending will likely leave at least one character's fate up in the air heading into Season 6. "It's going to be a harrowing one," Haas says. "As we've shown on the show, anytime the bells go off, it could be dangerous for anyone. I will say no one's safe on this finale."

Elsewhere, Dawson (Monica Raymund) and Casey (Jesse Spencer) find themselves at odds over in-law issues. "Dawson's dad has decided to shack up at the Dawson-Casey house, and they have different opinions on when he should be leaving," Haas explains.

Chicago Justice (NBC)

Airs: Sunday, May 14 at 9/8c

The newest member of the One Chicago family closes out its freshman season with an episode called "Tycoon," which executive producer Michael S. Chernuchin says is inspired by Arthur Miller's All My Sons. The West Wing alum Richard Schiff guest-stars in the episode as the largest real estate developer in Chicago who finds himself under fire after a crane collapses at the construction site of his latest project and kills one of his family members. "We kind of delve into what drives guys like this, that have a lot of money but still want to build more and want to be richer," Chernuchin tells TVGuide.com. "He's that kind of bold character."

The Justice team gets involved with the case because Schiff's character is an old friend of Cook County State's Attorney Mark Jefferies. "He asks for protection and puts pressure on Carl to solve the case quickly. ... He'll do anything to help them prosecute," Chernuchin says. "It turns out that there's a little more involvement on [Schiff's character's] part, and then he has to plead with his old friend for leniency."

Chicago Med (NBC)

Airs: TBA

Those red flags that Robin (Mekia Cox) has been exhibiting in recent episodes will come to a horrifying head in the Season 2 finale, with huge repercussions for Dr. Rhodes (Colin Donnell) and Dr. Charles, who's always dreaded that he has passed his own mental health issues on to his daughter. "Her condition continues to worsen and then takes a surprising turn," executive producer Andrew Schneider tells TVGuide.com. "It is the realization of [Dr. Charles'] worst fears. ... [And] Connor has his own family issues with mental illness. His mother committed suicide. So he's determined at all costs to save Robin and protect her. ... Her illness puts them at odds, in a profound way."

Rhodes also has to contend with a new star CT surgeon who will be introduced in the finale. In the romance department, April (Yaya DaCosta) finds a new love interest and the Will-Nina-Natalie love triangle experiences a major shakeup. "There are some big changes in that area that we've been hinting at," Schneider says. "There's something that acts as a trigger in the last episode that changes things for Will."

Criminal Minds (CBS)

Airs: Wednesday, May 10 at 9/8c

Shemar Moore returns in the Season 12 finale for the first time since his exit last season -- and he has a beard! We repeat: Derek Morgan has a beard! "Derek Morgan is a civilian now, so he doesn't look like his Agent Derek Morgan self. He's a dad, he has a beard, he's a little more casual," showrunner and executive producer Erica Messer tells us. Morgan is back not so much to help Reid (Matthew Gray Gubler) get out of prison but to bring the BAU a major lead in the mission to catch Mr. Scratch (Bodhi Elfman).

"It's tied to what happened to him last year a little bit," Messer says, adding that Morgan is shocked to be pulled back in suddenly. "Scratch isn't getting to Hotch (Thomas Gibson) to get us that message because Hotch is in Witness Protection, but he did get to Morgan even though Morgan is a civilian now. That's still a little disheartening that Scratch can have so much reach."

The Scratch and Reid arcs will be wrapped up, but you shouldn't rest easy. The show will pull off its first proper finale cliffhanger since Season 3. "It isn't a car exploding [like in Season 3], but it is a legit cliffhanger that we haven't done in a really long time, so that's kind of exciting," Messer teases. "We get to start Season 13 in a different way. You'll be asking the same type of question: 'Who was that?' 'Are they OK?'"

Criminal Minds: Beyond Borders (CBS)

Airs: Wednesday, May 17 at 9/8c

Season 2 will conclude with back-to-back episodes. The first hour features guest star Charisma Carpenter, along with Monty (Tyler James Williams) joining the IRT for his first mission in the field in Nepal. The second hour sees the IRT jetting off to Russia after a ballerina is kidnapped, but she's not the only one in trouble: Jack's (Gary Sinise) family, specifically his son Ryan (Matt Cohen), also gets roped in as Jack faces off with a former KGB agent who escaped from prison. "[Ryan's] a huge part of the finale," showrunner and executive producer Erica Messer says. "He is in danger within the season but by the time the finale rolls around it's more about Jack fighting a nemesis and his family getting involved as sort of collateral damage for that."

Designated Survivor (ABC)

Airs: Wednesday, May 17 at 10/9c

If we're to believe Designated Survivor creator David Guggenheim, then fans are in for a huge finale of ABC's political thriller. "The finale definitely delivers on all the suspense, mystery and conspiracy twists that we've been weaving all season long. All your questions will be answered," Guggenheim tells TVGuide.com. That would certainly imply that we'll get to know who is really behind the conspiracy that put Tom Kirkman (Kiefer Sutherland) in the White House and blew up the Capitol Building with most of the nation's government inside of it. The political turmoil surrounding Kirkman's presidency will also be addressed as others look to take his seat and his own staff deals with personal issues. And just in case you think everything will be hunky-dory, think again. The final hour of Season 1 will be "equal parts revelatory, heart-breaking, exciting and inspiring," Guggenheim says. Heart-breaking? Uh-oh.

Empire (Fox)

Airs: Wednesday, May 24 at 9/8c

Empire's two-part finale will bring closure to its major storylines, including Andre's (Trai Byers) scheme to kill his father Lucious (Terrence Howard) and Angelo's (Taye Diggs) vow to get revenge after his embarrassing proposal fail. Meanwhile, Cookie (Taraji P. Henson) will find herself banned from club Leviticus in Vegas, prompting her to assemble a team to get revenge on Giuliana (Nia Long). We'll also get our first glimpse of Demi Moore as a mysterious nurse who will cause a lot of drama for the Lyon family. But when Jamal (Jussie Smollett) is forced to shelve his album because of his father, that betrayal will create yet another crack in the Lyon family foundation that'll seem to be totally crumbling by the conclusion.

The Flash (The CW)

Airs: Tuesday, May 23 at 8/7c

Savitar won't be the only problem facing Team Flash in the Season 3 finale. "After discovering the true identity of Savitar, Flash and the rest of the S.T.A.R. Labs team prepare for the final epic battle with the God of Speed... while struggling with a major setback and how to save Caitlin from her destiny as Killer Frost," executive producer Todd Helbing says.

The run-up to the finale will also see Barry (Grant Gustin) and his friends having to contend with a slew of familiar foes, including a major recurring character. And with Savitar's prophecy that one member of Team Flash will fall, fans should prepare for the worst. "In typical Flash fashion, this season finale ends on a cliffhanger that'll leave fans and our team questioning how they'll move forward in Season 4," Helbing teases.

Fresh Off The Boat (ABC)

Airs: Tuesday, May 16 at 9/8c

The two-part finale kicks off in the May 9 episode when Michael Bolton, playing himself, approaches Louis (Randall Park) about becoming a silent partner in Cattleman's. Turns out the singer must be in Orlando for 183 days out of the year for tax reasons and Marvin (Ray Wise), who's done dental work on Bolton, had suggested the business deal. "[Louis] had trepidation of losing control of this fine establishment. But during the course of the episodes, I kind of lose control of that," Park teases. "Bolton definitely gets a little eager." (Sadly, you won't hear any Bolton tunes -- not even "Go the Distance" from Hercules, which came out in 1997, the year the show is currently set in.)

Jessica (Constance Wu) is all for the partnership because she wants the family to move so Evan (Ian Chen) can go to a fancy private school. Louis is hesitant at first, but they make the move (no pun intended). "It's a bit of a shock for them to move into this huge, huge house in this really fancy neighborhood," Park says. "They're moving in all their old furniture and there's so much space in this house. And they have to deal with this new world, even Evan at this private school dealing with the headmaster played by Howard Hesseman -- just dealing with a different culture, which is pretty much what our family was dealing with our first season."

Those issues won't be tied up when the season ends. "Basically their entire livelihood is at stake," Park says. "There are some big problems that they come into that aren't solved by the end of the season."

The Goldbergs (ABC)

Airs: Wednesday, May 17 at 8/7c

It's graduation day on The Goldbergs' Season 4 finale, which is directed by Kevin Smith, who also helmed the Batman episode earlier this season. Naturally, Beverly (Wendi McLendon-Covey) is gonna have some trouble letting her first and oldest schmoopie, Erica (Hayley Orrantia), flee the nest, but so is Barry (Troy Gentile) -- not about his sister, but his girlfriend Lainey (AJ Michalka), as you can see in our exclusive first look photo. You should be worried about them, and Erica and Geoff (Sam Lerner). "They're kind of parting ways, so there are a lot of similarities. There will be one breakup and one couple will be staying together," creator and showrunner Adam F. Goldberg teases.

In other matters of the heart, Dana (Natalie Alyn Lind) returns, creating a love triangle for Adam (Sean Giambrone) and his new girlfriend Jackie (Rowan Blanchard). Goldberg had initially hoped for that to play out next year, but after Lind was cast in Fox's X-Men pilot, he "packed an entire season's worth of that whole dynamic" into the finale. "Adam is dealing with your first love versus your new girlfriend, and all the feelings that come with that," Goldberg says. "It's really, really sweet."

And though the show's all-but-certain fifth season hasn't been announced yet, Goldberg is definitely going to employ one of his legendary stories about his mom next season: Real-life Beverly dropped off groceries for her son one weekend and insisted on spending the night in his dorm because it was allegedly too dark to drive home. "I would obviously love to do it with Adam because that's obviously me and that was my experience, but if it took Erica 95 episodes to graduate, I assume it's going to take Adam another 95 episodes to graduate high school," he says. "So I'm just going to do it right now."

Gotham (Fox)

Airs: Monday, April 24 at 8/7c

Gotham's third season is going out in a big way! First, fans will experience the final showdown between Penguin (Robin Lord Taylor) and Nygma (Cory Michael Smith), the latter of whom will fully transform into his famous alter ego, the Riddler. But Nygma won't be the only character evolving at the end of the season. Bruce (David Mazouz) will be closer than ever to becoming the Dark Knight after a fateful encounter with Ra's al Guhl (Alexander Siddig). "You're going to see Bruce take steps toward becoming that iconic character that's much more accelerated than anything we've watched up to his point," executive producer John Stephens tells us. "It's going to be incredible to the show fans and Batman fans in general." Oh, and don't forget Harley Quinn arrives at the end of the season as well!

Grey's Anatomy (ABC)

Airs: Thursday, May 18 at 8/7c

Though it's not officially billed as a two-parter, the Grey's season finale goes hand in hand with the penultimate episode. "There are two events that happen," star Debbie Allen, who directed the season-ender, tells TVGuide.com. The back-to-back events occur outside the hospital and then within the walls of Grey Sloan, and given that the finale is described as being "on fire," we're guessing Season 13 will include a Shondaland catastrophe for the ages. But in addition to any literal explosions we might see, things also get heated between the doctors, especially Meredith (Ellen Pompeo) and Maggie (Kelly McCreary), once Meredith's romance with Riggs (Martin Henderson) comes to light. "All the relationships that we've been following all year will come to a head, one way or another," Allen says.

Hawaii Five-0 (CBS)

Airs: Friday, May 12 at 9/8c

Hawaii Five-0's Season 7 finale is an extension of Episode 19, in which the team discovers a sex trafficking ring on the island. This installment will be more action-packed than the previous episode, but will also have a huge emotional impact on Kono (Grace Park). "It's going to play into a bigger arc and a little bit of a cliffhanger for her at the end of this season, and something that she's committed to seeing through," showrunner Peter Lenkov tells TVGuide.com. "Because it's not just something that's happening on the island. It's an epidemic that's happening all over the country. So, she sort of takes on this cause singlehandedly, and is determined to find anybody who's behind sex trafficking. It's a little bit of a heavier story for us, but it's a good journey for her and it's great for us, because it's real and it's got a lot of weight behind it." But will Kono's commitment to the cause pull her away from Five-0? Anything's possible.

21 of 33 Tyler Golden/THE CW

Jane the Virgin (The CW)

Airs: Monday, May 22 at 9/8c

There's always a lot happening at once on Jane the Virgin and the Season 3 finale is no different. In addition to revealing exactly what happened the night Scott died, there will also be another big event in Jane's (Gina Rodriguez) life, but creator and executive producer Jennie Snyder Urman promises it won't be traumatic like it was in seasons' past. "[Jane] already had her big trauma of this year. ... Things come full circle a little bit and Jane gets to breathe," she teases. "There are still big twists and turns of course in the finale, but it's not a traumatic finale for Jane."

Adding to the good news train is the fact that Brett Dier will return in flashbacks as Michael, while Teen Wolf star Tyler Posey will make his first appearance as Adam, a man from Jane's past who Urman reveals has a connection with Michael. He'll be back in Season 4, so take from that what you will.

Elsewhere, Rafael is in for quite a bit of drama in the final stretch of episodes as the mystery of his parents comes back into play while he searches for Rose (Bridget Regan) and attempts to sort out his growing feelings for Petra (Yael Grobglas), who does not share his affections.

Kevin Can Wait (CBS)

Airs: Monday, May 8 at 8/7c

The first season of Kevin James' TV return has featured guest appearances from old friends like Ray Romano and Adam Sandler, but no guest star is as exciting as the one coming up in the season finale: Leah Remini, who played James' wife for nine seasons on The King of Queens. In the two-part finale, Kevin comes out of retirement for one last job. He's going back undercover with Officer Vanessa Gallucci (Remini), who plays his wife for the purposes of the investigation. There's no tension between her and Kevin's real wife Donna, though; "They're more united in pointing out the less-than-fine things about Kevin," reveals Erinn Hayes.

Law & Order: Special Victims Unit (NBC)

Airs: Wednesday, May 24 at 9/8c

In the two-hour season finale, SVU is once again ripping from the headlines. But instead of a salacious celebrity scandal, this time the NBC staple is drawing inspiration from the very real divide in our country and the current rise in public Islamophobia. In "American Dream" and "Sanctuary," Benson (Mariska Hargitay) and her team must investigate a hate crime against a Muslim family that results in the death of their daughter. However, when the key witness in the case is deported, Barba (Raul Esparza) is forced to drop charges against their lead suspect. As tensions continue to rise in the wake of the suspect's release, the public protests surrounding the case turn violent, and Benson is forced to go to great lengths to make an arrest.

Airs: Tuesday, May 9 at 8/7c

NCIS' Season 14 finale picks up after a "big twist" that closes out the penultimate episode, in which McGee (Sean Murray) and Delilah (Margo Harshman) struggle to plan their wedding while dealing with stressful demands from both of their families, not to mention the cases they're both working on. The decision they make - which will be revealed in the finale - is a surprising one, but one that executive producers Frank Cardea and George Schenck promise will be satisfying for fans. "They'll be very happy," Schenck says about fans who have been patiently waiting for McGee and Delilah's nuptials. "They'll go through a lot of angst with them, but they'll really appreciate the way it ends." But not everything in the finale is a cause for celebration: Some of the agents head down to Paraguay after the dismembered hand of a Navy Seal is found in the jungle, and the case takes an ominous turn. "When they get down there, things are not what they thought they were, and they end up in a situation that they did not foresee," Cardea says. An explosive cliffhanger ending will leave at least one character's life in the balance.

Last year, it was Sam's (LL Cool J) son who was in danger. This year, it's his wife. That's right: Sam's nemesis Tahir Khaled (Anslem Richardson) returns to wreak more havoc, kidnapping Sam's wife Michelle (Aunjanue Ellis). That only spurs Sam to go rogue to stop Khaled once and for all. ER's Erik Palladino also guest-stars as CIA Officer Vostanik Sabatino.

The long-simmering takedown of that shady Mayor Hamilton (Steven Weber) that the NCIS: New Orleans squad has been working so hard to make happen finally concludes when the frustrated team calls in FBI Assistant Director Isler (Derek Webster) to help them expose and stop the sinister scheme has planned for residents of Clearwater.

Once Upon a Time (ABC)

Airs: Sunday, May 14 at 8/7c

A musical event leads Once Upon a Time into its Season 6 finale as Emma (Jennifer Morrison) prepares to face off against the Black Fairy in "the final battle" as the last chapter of the story book. The finale itself will see the veteran series return to its roots by featuring a duel between good and evil. However, Once also remains on the cancellation bubble, with rumors flying that if it is renewed for a seventh season, the show will shift gears and focus on a new side of Storybrooke. That means fewer of your favorite characters will likely be back, so fans should brace for the big showdown to have major consequences for Storybrooke heroes like Snow White (Ginnifer Goodwin) and Prince Charming (Josh Dallas).

The Originals (The CW)

Airs: Friday, June 23 at 8/7c

The Mikaelsons were at their lowest point - and dealing with the deepest possible rift between them and Marcel (Charles Michael Davis) -- at the start of The Originals' fourth season. Since then a mysterious dark magic dubbed the Hollow has invaded New Orleans and made Hope Mikaelson (Hope Fontana) a target. According to executive Michael Narducci, who will part ways with the series after the season finale, putting children at risk is the one thing that could bring the Mikaelsons back to New Orleans and force the original vampire family to at least make peace with Marcel.

The Hollow has already taken control of Klaus (Joseph Morgan) and Marcel and proven that it can make them see, feel and do whatever it wants. Freya (Riley Voelkel) was able to cleanse them of the presence, but it's clear the Hollow won't stop until it gets the power it wants -- and who has more power than the Mikaelsons and Marcel? "The Mikaelson family will be changed forever," Narducci says about the final episode. "Some characters will have happy endings and some characters will have bittersweet endings. I'm definitely looking forward to fans seeing what we have."

Quantico (ABC)

Airs: Monday, May 15 at 10/9c

After a "huge time jump" of a "couple months" in between Episodes 21 and 22, the Season 2 finale will wrap up the task force's quest to take down the shadow group and its collaborators, and it will contain yet another prescient storyline. "[Writer] Jordon Nardino pitched the endgame and [writer] Justin Brenneman was like, 'No way! That could never happen,'" creator and showrunner Joshua Safran teases. "And then [recently] a very reputable publication said this thing might happen. So Justin sent it to all the writers saying, 'I was wrong!'" Any guesses?

Quantico filmed two endings in case Season 2 is in fact the end of the series. "There's a small cliffhanger version of the finale and there's also a nice, tied-up-with-a-bow version of the finale," Safran says. "Even the one that ties everything up with a bit of a bow, I wouldn't call it a happy ending. It's not a sad ending, but it's a realistic ending for these characters." But Safran promises that there won't be any major cliffhangers dangling either way. "Everything with the collaborators is tied up by the end either before or after [the time jump]. But 'tied up' doesn't necessarily mean a happy ending, but there's a definitive end to that storyline."

Reign (The CW)

Airs: Friday, June 16 at 9/8c

It's war between Mary (Adelaide Kane) and Elizabeth (Rachel Skarsten) as Reign prepares to say goodbye after four seasons. The Queen of England has officially sent her troops into Mary's homeland of Scotland, and now the only question that remains is whether the CW series will remain true to history and depict how the war actually played out, meaning Mary loses both Scotland and her head. While Reign has taken many creative liberties over its run, it has stayed true to the big landmark events, which means fans should probably prepare to say goodbye to Mary in a very bittersweet way before the series ends. If you're a true romantic, you can also think of it as her reuniting with Francis (Tony Regbo) in the afterlife.

Who killed Jason Blossom? Was it Fred (Luke Perry)? Was it FP (Skeet Ulrich)? Was it (old man) Smithers? The truth behind Jason's murder has been the central mystery guiding Riverdale's soapy first season, and fans will know the answer by the time the credits roll on the finale. That means you better get your bets in place beforehand! In addition to wrapping up the season-long mystery, we'll also find out which way Archie (KJ Apa) is leaning in the still-largely-untested Betty (Lili Reinhart) and Veronica (Camila Mendes) love triangle as the show sets up a second season that potentially will take a turn into the supernatural.

Ruland, aka Mystery Woman (Zoe Perry), and Peus (David Warshofsky) may have bought the electoral votes for Mellie (Bellamy Young) to become president, but the former first lady still needs to be sworn in. "It is not official yet," Young teases of the two-hour finale, which covers Mellie's scheduled inauguration. "We're certainly in a battle at this point between good and evil. ... By the finale, some folks will have become people you couldn't have imagined they would." That may include Mellie herself, whose White House dream is "too close now and she's gonna give it her all." "She's terrified [of Peus]," Young says. "But she's at a time in her life where she can't succumb to the terror. She has to walk forward in spite of the terror."

Despite defying the Mystery Group's orders to name Peus her VP, Mellie's all-female ticket of her and Luna Vargas (Tessie Santiago) remains intact. "[Luna's] still finding her footing, but she's proving to have a good heart and to be a fast learner and to be a great member of the team," Young says. "Mellie is very proud to have an all-female office and really believes that together they can restore hope to the country." But that doesn't mean Team White Hat will loop Luna in on all the crazy drama. "I will just say that trust takes time."

You can also expect another cliffhanger and Quinn (Katie Lowes) to be the MVP. "My favorite finale moment belongs to Quinn," Young shares.

As Supergirl speeds toward its second season finale, Kara (Melissa Benoist) will face off against Mon-El's (Chris Wood) terrifying mother Rhea (Teri Hatcher). But Kara won't be alone in her endeavors to protect National City and Earth: Tyler Hoechlin's Superman will finally make his anticipated return in the Season 2 finale. Also returning at the end of the season is Calista Flockhart's Cat Grant, a fan favorite character who departed the show earlier this season to find new challenges. She'll appear in the final two episodes of the season, and if you don't believe there's going to be some kind of sweet pep talk between the two women where they bond some more, you've been watching a different show.
