Jake performs in the “Guilty Pleasures” episode. Is he doing a love song to win back Marley? Will he need to win back Marley?

Wow! We almost didn’t recognize Marley with the heavy eyeliner and all that skin. In addition to sporting some serious arm bands and a tube top, she appears to be sporting some serious ‘tude. Why haven’t we seen this side of her before?!

Noooooooooooooo! Blaine is in a Cheerios uniform! But at least it will give Coach Sue something to do besides ruin Wemma’s non-wedding?

New roommates Santana and Kurt partake in some pillow talk. They are so talking about Rachel behind her back, right? Right.

Kurt blindfolds Santana and Rachel to surprise them with what looks like an impromptu pillow fight? It must be nice to live in such a spacious loft.

Rachel and Santana practice their best Taylor Swift “shocked” expressions. Uh, is this the part where Rachel finds out her boy Brody is sleeping around? Cuz that needs to happen.

Kurt takes a closer look at himself in the mirror. Now if only Rachel would do that and lose the feathered hair and bangs!

Finn and Will perform with their best “mad” faces in the appropriately titled “Feud” episode. So who is a jet? And who is a shark? Wait, didn’t they do West Side Story last season?!

Fingers crossed that this is a picture of Will, Blaine and Jake performing a tribute to ‘N Sync’s No Strings Attached album.

Seriously? Someone needs to tell Finn that he graduated, and that Mr. Schue is back from D.C. for good. He obviously didn’t get the memo.

Emma shows a hint of a smile as she’s serenaded by Will. By the way, who is Emma staying with while she hides out from Will? Hopefully not those crazy parents of hers…

Will forces asks the New Directions to help him sing to Emma. But since this episode is paying tribute to great music scenes in movies, shouldn’t he be holding a jukebox over his head and playing Peter Gabriel? Say Anything forever!

Will looks less than pleased when talking with Emma. Maybe she insulted his excessive use of hair gel? Or his rap skills?

Cheesy alert! Marley and Jake do their best Ghost re-enactment as they make pottery together. Just watch out for Tony Goldwyn!

The New Directions put their best feet forward for a big group number. Could this be the big “Shout” performance? If so, they need to get on their feet as soon as possible!

Jake and Ryder debate whether to do the electric slide, the chicken dance or start a conga line at the reception.

Cheers to Quinn and Santana's reconciliation, but why didn't Quinn bring her older Yale professor beau as her date?

Kurt to Tina: "Back off, Tina. I know you know that Blaine is gay. Just because I am playing the field in New York doesn’t mean he and I aren't going to start our artists colony together."

Emma and mini-Will Finn challenge the New Directions to find their inner powerhouses for Diva Week. It's not really official until someone writes it on the white board, right?

New Directions stretches the McKinley High budget, namely the electricity bill, for a big group performance during diva week.

Ryder and Jake immediately start brain-storming diva costumes. Gaga or Nicki Minaj? Whitney or Mariah?

Tina goes retro with this revealing hot-pink unitard just like the one Madonna wore in her "Hung Up" video.

It’s not awkward at all! Quinn performs in the auditorium with former loves Finn and Puck. Might we suggest an acoustic version of Taylor Swift’s “We Are Never Ever Getting Back Together?” Just kidding. Kind of.

Quinn gathers with fellow McKinley High grads Santana, Mike, Puck and Mercedes to school the New Directions. Rule 1. Don’t text and drive, kids!

Cheerios unite! Quinn takes the lead during a nicely choreographed musical performance with Brittany and Santana.

Quinn walks the halls of McKinley with baby daddy Puck and his half-brother, Jake. We’re not sure why but she looks angry enough to slushy someone. Run for cover!

Quinn gives a very pouty Kitty a pep talk in the choir room. Can she put this bad egg on the right track? If anyone can, it’s Quinn.

Kurt invites boss Isabelle (Sarah Jessica Parker) over for Thanksgiving. Because that’s what every Vogue editor wants to do, go all the way to Brooklyn to eat carbs.

Blaine puts his new cape to good use as he runs through the halls of McKinley in his superhero get-up. If this is how he’s dealing with his split from Kurt, might we suggest the therapist Emma used to help her with her OCD?

We’re not sure what the urgency is, but Artie appears to be the brains, literally, behind the New Directions’ latest operation. Also, Becky is back! Does that mean Helen Mirren is too? (Please say yes.)

OK, we know we complained a lot about Mr. Schue’s endless supply of bland sweater vests, but we’re not sure if Finn wearing a musical note on his chest is that much of an improvement.

It’s just a guess, but Sugar sure looks like she’s doing the “Gangnam Style” dance in this new photo from sectionals.

After their disastrous trip back to Lima for Grease, who can blame Kurt and Rachel for staying in New York for Thanksgiving?

According to the official caption, Kurt “begs” for another chance to audition for NYADA. Hello?! What could be better than working at Vogue?!

Rachel is a vision in white as she performs at NYADA’s prestigious winter showcase. Let’s hope the evil Cassandra July is nowhere in sight.

Brittany bonds with newbie Ryder in this year’s Christmas episode. Fingers crossed it’s not socks!

Marley’s mom, Mrs. Rose, and Coach Sue watch a performance together. If only Mrs. Rose knew what Coach Sue called her daughter …. oh, wait! Sue was never able to craft a witty insult for Marley. Oh, snap!

Make your best guess: Puck is giving his half-bro Jake tips on a) how to score with a Cheerio b) how to score with a substitute teacher who also adopted your baby c) how to clean pools or d) all of the above.

Blaine may have been too depressed to play Danny, but he makes one dreamy teen angel. And are we the only ones that think Sugar is totally rocking the pink hair?

Wow, Marley makes one hot Sandy with her big hair and skin-tight black leather pants. Take that, Kitty!

The Grease cast gathers on stage to soak in the applause. Can Sam Evans always wear a leather jacket from now on? Please and thank you.

Kitty hosts a sleepover for the girls of New Directions. We’re not sure what scheme she's up to, but why on earth did anyone actually go?

They may both be after Marley’s affections, but Jake and Ryder come together for what looks to be a "super" duet.

Those New Directions members sure clean up nice! Ryder and Jake sport matching suits, glasses and fedoras for a performance.

Cover your eyes — literally! Bad boy Sebastian returns to compete at sectionals with The Warblers in the Nov. 29 episode.

New Directions breaks it down with some impressive dance moves at sectionals. But will it be enough to get them to the next round?

More cool dance moves from New Directions. Could this be part of the group’s recently teased performance of Psy's "Gangnam Style"?

We have no idea why Kurt is smiling, but in our wildest imaginations, it's because Blaine went back in time and didn’t cheat on him. Now they can get back together and start that artists' commune! Klaine 4eva!

Cassandra July perfects her disapproving face during a dance rehearsal at NYADA. Uh oh, did Rachel accuse her of having alcohol on her breath again?

Brody stands shirtless in a dance rehearsal room. Dear Rachel, you are single now. Time to move on — and preferably with him!

Rachel looks worried as she gets ready for dance class. Was someone too busy ogling Brody’s six-pack instead of studying her dance moves? If so, we don’t blame her!

Mr. Schue laughs it up from the audience as he watches the New Directions perform a musical. But why is Emma nowhere to be seen? Hmm…

The New Direction guys do a great job of recreating a classic scene from Grease. But who gets to drive home the hot red car after the musical is done?

"Put your hands in the air, shake your body down...." Oh, wait the glee kids are probably not performing an Akon song for their Grease production but either way, everybody wins when Sam lets even the tiniest amount of skin show. Viva White Chocolate!

If Kitty hates New Directions so much, why on earth is she on stage during a rehearsal? Is she that desperate to get Jake back? Our money is on her playing a very biting Rizzo, while Marley will play the equally doe-eyed and innocent Sandy, natch.

Now that Finn has no job and no girl, it looks like he is going to replace Kurt as the sad ex-glee clubber that pathetically lingers the halls of McKinley (probably to the tune of a Journey song). Luckily, he at least finds some fresh blood in newbie Ryder (Glee Project winner Blake Jenner).

Coach Beiste, where have you been all of our lives and when you are going to take Mr. Schue back to that cowboy bar? Sadly, it sounds like things are serious this time when she must give Emma some advice after Emma and Will’s fight in the break-up episode.

Judging by the shocked look on Emma’s face, Coach Beiste said what we’ve all been thinking: “Will acted like a self-absorbed jerk, and you should make him go to D.C. alone to wallow in his own pity!” Coach Beiste knows what’s up.

Isn’t it a tad too soon for the McKinley High Class of 2012 to be reuniting? It’s never too soon when it involves some of our favorite grads like Mike and Mercedes. But can someone please help Finn out? He looks like he’s taking this production too seriously already.

When will we find out which celebrity is Coach Sue’s baby daddy?! And more importantly, when will we find out what awesome babysitting service Coach Sue uses so that she never has to worry about her newborn?!

In Season 3, Blaine helped contribute to the whole red jeans craze with his memorable performance of “It’s Not Unusual.” Now, apparently, red is out and mustard yellow is in. Good to know? Also, who do you think Blaine should play in the Grease musical?

Mike, Mercedes, Finn and Artie judge the auditions for Grease. Seriously, someone make a knock, knock joke and make Finn smile. This is depressing!

Marley and Unique perform together on stage. We don’t know what’s going on with Marley’s baggy pants but this would be the time for a fashion intervention from the stylish Unique pronto. If Rachel can get a makeover in the Vogue couture closet, then Marley at least deserves some flattering jeans.

Another shot of Marley and Unique performing, with a better view of said pants. Don’t ignore this cry for help! It’s not too late!

Rachel sports a sexier look thanks to some very red lipstick, which she sports while trying her best to pretend she doesn’t notice Brody’s impressive arm muscles.

Rachel collaborates with Brody on a highly choreographed (and highly suggestive) number. We’re sure she’s performing a Britney song, but this image looks more like the music video from another X Factor judge… Paula Abdul’s “Cold Hearted Snake.”

New girl Marley seems to be fitting right in with the rest of the gang, namely Unique and Tina, during a big group number in the gym. Won’t Coach Sue be mad they’re encroaching on her turf?

The New Directions, including returning Glee Project winner Samuel Larsen as Joe, get their latest glee club assignments. But hello?! Where is Joe’s guitar?

Rex Lee joins Lohan at the judges' table, and it doesn't look like they're going to agree on who should take home the trophy

Tina will bump her head and imagine that each of the New Directions members have switched places. She imagines herself as Rachel

Tina also sees Mike as Joe and Rory as Sam. Hilariously, Rachel totally pulls off Tina's gothic chic

The best of all? Tina imagines Mr. Schue as Sue Sylvester. Lesson: Anyone looks good in a track suit!

Plus: Gloria Estefan will make her debut as Santana's mother. Thanks for the first look, Brad Falchuk!

Mercedes shares a dance with the star of The Justin Bieber Experience, aka Trouty Mouth, aka Sam. We sure hope these lovebirds can stay this close after Mercedes graduates.

Is someone going to die at prom?! We have no idea, but Tina and Mike, both dressed in black, sport looks of utter confusion – and maybe sadness?

Quinn takes the stage and performs during prom. But the question still remains: who will she take as her date?

Principal Figgins busts a move during the McKinley prom. Now we understand why Sue wasn’t able to resist him way back when.

And the world’s cutest chaperones award goes to… Mr. Schue and Emma, who share a sweet moment on the dance floor. It’s not a Will solo rap session, but we’ll take it.

In a shocking (not) twist, Blaine’s obsession with bowties continues. However, we have no idea how to explain Kurt’s surprisingly casual ensemble.

Mercedes sparkles in a purple princess gown. Is Kurt hiding a hair gel mishap under that top hat? Has he learned nothing from Blaine?!

Tina, Santana and Brittany perform together on stage in their prom finest! Place your bets now on whether they decide to pick from ABBA’s catalogue again, or if they take a page from the guys’ playbook last year and perform “Friday.” Please, please let it be the latter.

Sugar, Santana, Brittany, Mike and Puck celebrate senior ditch day at a local amusement park. Puck looks pretty excited, but doesn't he celebrate senior ditch day like every two weeks?

Judging from the upset look on her face, Rachel is so not buying whatever Artie is selling when he performs for the glee club.

Apparently the Anderson brothers do not share the same taste in fashion. While we all know how much Blaine loves a good bowtie, his older brother Cooper (special guest White Collar's Matt Bomer) rocks a brown leather jacket while teaching a master acting class to New Directions.

Is Cooper teaching Blaine how to look angry? Try all you want, but we don't think it's going to stick.

Oh look, it's Blaine and the amazing Technicolor televisions! The ex-Warbler and Cooper take their brotherly love into the digital age for a performance.

Could this be the last competition for some of the New Directions’ seniors? Probably not, there are still more episodes this spring!

Special guest star Ricky Martin hangs on the edge of his seat during a dance number with Brittany and Mike. Who's teaching whom to shake their bon bon?

He may not have Mr. Schue's rapping skills, but the New Directions sure look like they're having fun with the new Spanish teacher. Now if he can also write on a whiteboard, Mr. Schue might be in some serious trouble.

Mr. Schue dusts off his conquistador costume from last Halloween (kidding … kind of) for a performance, possibly in his quest to regain his calle (that's "street" in Spanish) cred when the new Spanish teacher comes to town?

Mr. Schue, Emma and Coach Beiste chat in the teacher's lounge. Do we smell a Sue-like scheme to get rid of Martin's character brewing or did someone just burn the popcorn?

We might have figured Puckerman for a Jersey Shore fan, but this time he gets Kurt, Mike and Artie in on the fist-pumping action during a group performance. Are they performing Enrique, or Pitbull perhaps?

Unlike Santana and the majority of New Directions, Rachel's two dads (guest stars Jeff Goldblum and Brian Stokes Mitchell) clearly find her constant need for attention completely endearing during a dinner party. Could it be a dinner party celebrating their daughter's engagement?

Rachel and dad Hiram (both actors are Broadway vets in real life) give the term 'dinner theater' a whole new meaning.

It's raining men, er… tiny pieces of red and pink heart-shaped confetti for Sugar! Looks like Artie and Rory will compete for her affections on Valentine's Day.

Mercedes sings a love song, but the real question isn't what song she is performing, but rather who she's singing to -- Sam or Shane? White chocolate or cocoa babies? The suspense is killing us!
