Every The Vampire Diaries and The Originals Easter Egg in Legacies Season 1

Legacies may have accrued a whole new generation of viewers who've invested in Hope (Danielle Rose Russell), Landon (Aria Shahghasemi), and the Saltzman twins' stories this year, but there are still a bunch of us who got grandfathered in thanks to our never-ending obsession with The Vampire Diariesand The Originals.

Luckily for us, while Legacies is more than able to stand on its own two feet, the show still took time in Season 1 to pay homage to the two series that came before it, and the beloved characters that are no longer on our screens every week. Over the course of the season, TV Guide has kept an eagle eye on the lookout for Easter eggs from The Vampire Diaries and The Originals, which we've compiled in a pretty impressively sized list below.

Without further ado, please enjoy this rundown of every reference to The Vampire Diaries and The Originals, big or small, in Legacies Season 1.

1. The Stefan Salvatore (Paul Wesley) Memorial Library (Episode 1). The Salvatore library may have once been a place for Stefan and Damon (Ian Somerhalder) to drink bourbon and make bad choices, but now that the boarding house has been transformed into a school, the library is a popular hangout for students. It's also been renamed The Stefan Salvatore Memorial Library in honor of him sacrificing his life in The Vampire Diaries series finale to save the town of Mystic Falls from Katherine Pierce (Nina Dobrev) and her evil hellfire. The school even built a special case that holds Stefan's journals, his daylight ring, and even the necklace he gave Elena (Nina Dobrev).

2. Teachers summoning hellfire (Episode 1). Speaking of Hellfire, Josie (Kaylee Bryant) mentions in her tour of the school that their chemistry of magic professor accidentally incinerated himself with the stuff. Hellfire played a huge role in The Vampire Diaries series finale, as it was summoned by Katherine Pierce (who'd been cooling her heels in Hell since Stefan murdered her) to destroy Mystic Falls once and for all.

3. "It's not a competition." (Episode 1). In the pilot, M.G. (Quincy Fouse) and Josie have a little talk about Lizzie (Jenny Boyd) staking her claim on Rafael even though he's already clicked with Josie. Josie refuses to feel hurt about her twin beating her to the punch though, telling M.G., "It's not a competition," which is actually a callback to a line from Bonnie Bennett (Kat Graham) in The Vampire Diaries pilot in reference to Elena beating Caroline (Candice King) to the Stefan Salvatore punch.

4. Vervain in the water supply (Episode 1). Also in the premiere was the ever-popular "sheriff slipping vervain into the town water supply" move, which was a habit the former Mystic Falls secret council formed as a means of warding off vampires. This time around, the sheriff happens to be Matt Donovan, who appears to frequently slip vervain into the gas station coffee. Let's just hope he does it to ward off strange vamps instead of the kids at the Salvatore School.

5. The werewolf curse (Episode 1). While explaining the supernatural world to Landon, Alaric (Matthew Davis) makes reference to the werewolf bloodline curse passed down from parent to child, which is triggered when someone with the gene murders a human. While the curse was never fully explored on The Vampire Diaries, The Originals explained its origins as a curse cast by The Hollow in her dying moments on her tribe in retribution for killing her.

6. "Not now, Dana!" (Episode 2). Lizzie's rival at Mystic Falls High, Dana Lilien, is actually a nod to a minor character on The Vampire Diaries, as is Lizzie's line, "Not now, Dana!" at their flag football game. A chipper girl named Dana periodically appeared as a student and fellow-cheerleader on The Vampire Diaries, but she became a bit of an inside joke with the fans after one of her exchanges with Matt ("Not now, Dana!"). She inevitably met her end at Stefan's hand (well, fangs) on Senior Prank Night in Season 3, but, "Not now, Dana!" will live on forever.

7. Bonnie's magical assistance (Episode 5). As always, when our heroes are in a pickle, they call up Bonnie to provide a magical fix it. In this case, Dorian called Bonnie to help him track down and summon a vampire named Oliver who used to be the one true love of a Dryad who'd been thrown into Malivore. This Easter egg was mostly just a name drop, but it confirmed that Bonnie is still alive and still practicing magic.

8. Klaus' time in New Orleans (Episode 7). The Necromancer mentioned in his walk through Hope's subconscious that he spent a great deal of time in New Orleans before the 1920s since Klaus was always good for his business, killing people all the time. That was a subtle nod to the Klaus' murder spree on The Originals which subsequently forced him and Rebekah (Claire Holt) to flee to Chicago in the 1920s when Mikael showed up to hunt them down.

9. Ripper vampires (Episode 7). After discovering some students feeding on townies, Dorian explains what a Ripper is to Kaleb (Chris Lee), defining it as a vampire who is driven by obsession and the gratification of their own desires, even if that means feeding to the last drop and ripping the bodies apart. He says this in reference to Stefan murdering his own family when he went on Ripper bender with Klaus in 2010 (set between Season 2 and 3 of The Vampire Diaries) and even implies that M.G. is susceptible to becoming one.

10. Damon and Elena's babies (Episode 10). When Lizzie wished for an alternate reality where Hope never came to the Salvatore School, we saw Josie mention Damon and Elena's kids while explaining why the school is so hard up for money. Apparently, the Salvatores had been very generous to the school, but they had their own kids to take care of, confirming that at least in this alternate timeline, Delena had babies! In yet another alternate reality, Josie made mention of Stephanie Salvatore, who is almost definitely Damon and Elena's daughter.

11. Klaus and Caroline as "Enemies of the State" (Episode 10). In Lizzie's wish world where Hope was never born, Klaus turned off his humanity and started a war, outing supernaturals to the world. We saw his face on wanted posters, and a newspaper clipping had drawings of him and Caroline, declaring them enemies of the state. Some super industrious fans even zoomed in on the newspaper and discovered that Caroline was referred to as "his wife, Caroline Mikaelson," revealing that in this world, they were married, giving a pretty major nod to the Klaroline romance that never quite got its time in the sun on The Vampire Diaries or The Originals.

12. Kai Parker footnote (Episode 10). When Alaric was researching The Merge, we saw his notes in the margins of the book, The History of the Gemini Coven. Kai Parker's name was scribbled in the margins next to the paragraph explaining The Merge and how the ritual pits twins against one another in a bid to rule the coven. Kai, the last leader of the Gemini coven and the twins' uncle, was the big bad of The Vampire Diaries Season 6, and he was locked away in a prison world (twice) to keep him from wreaking havoc on the world.

13. The painting Hope made with Klaus (Episode 12). While trying to determine who really set the fire that ruined Spring Break three years ago, Hope told Lizzie that the fire destroyed the only painting she ever created with her dad. Considering this fire predated The Originals final season, we can only assume she meant the watercolor painting she made with Klaus the day she first met him in The Originals Season 4.

14. The Crescent Pack (Episode 13). When M.G. went missing on spring break, Hope opted to use a "family recipe" from her mother's wolf pack, the Crescent Pack, that would allow Rafael to access his wolf mind while still in human form. In addition to their ability to turn at will, the Crescent Pack were once under a curse placed on them by Marcel which meant they were only human during the full moon and had to be in wolf form the rest of the month, which would have made this kind of recipe invaluable to them.

15. Caroline's ballgown (Episode 14). To help Hope's bid for the Miss Mystic Falls title, Lizzie lent her a gown that used to belong to her mother Caroline, but both girls only later found out that the dress was actually a gift from Klaus Mikaelson. On The Vampire Diaries, when Klaus was first trying to woo Caroline, he sent her this ballgown along with an invitation to his family's ball with a request to save him a dance.

16. Freya explains The Merge (Episode 15). When Lizzie clued Hope in on The Merge mystery, Hope called her Aunt Freya (Riley Voelkel) to ask if she knew what the ritual was and how it pertained to the Gemini Coven. Freya explained the truth -- that Gemini twins have to overtake each other in a ritual when they turn 22 that kills one of them in the process. It's no wonder Freya had the answer given the Mikaelsons' familiarity with siphoner witches.

17. The reverse Kyanite ring (Episode 15). After the Crescent Pack elixir muddled Raf's mind, Hope gave him a ring that let him shift into a wolf permanently instead of just on the full moon. She told him it's like a "reverse kyanite ring," which is used to stop wolves from shifting on the full moon. Said rings were developed in Season 1 of The Originals when Klaus was trying to win over the werewolves of New Orleans.

18. "There's always a loophole." (Episode 16). The episode title of the Legacies Season 1 finale was one major homage to the mythology of both The Vampire Diaries and The Originals, which was based on the theory that nature always finds a balance. No supernatural being could ever be truly immortal because nature would create a loophole that provided a way to kill it in order to maintain balance; for the Original vampires that loophole was the white oak wood that could kill them, and for Malivore, it was Hope's existence as a tribrid of the three species that created it.

19. Wickery Bridge (Episode 16). In the season finale, Alaric got stuck behind a roadblock because the Triad blew up Wickery Bridge. Wickery Bridge was a staple of The Vampire Diaries as it was the site of the car crash that claimed the lives of Elena's parents and the crash where she later died and became a vampire. It also happened to be entirely made of white oak, the only wood that can kill an Original vampire, which is why Rebekah burned it to ash in Season 3.

20. The Travelers (Episode 16). The Triad used a creepy blood fountain to nullify the school's magic in the finale, which Alaric revealed to be a creation of a coven of witches called the Travelers. These witches were the big bad of The Vampire Diaries Season 5. A curse had been placed on their line centuries ago that prevented them from ever settling in one place, making them nomads. They specialized in body-jumping, doppelganger magic, and the previously-mentioned magic nullification.

21. The Ascendant (Episode 16). Alaric wasn't just keeping his daughters' Gemini heritage a secret from them, he was also hiding a mystical trinket called the Ascendant in his bookshelf. On The Vampire Diaries, the Ascendant was a magical device that allowed witches to harness a celestial event to create a portal to another world -- in this case, the Ascendant Josie found was one she and her sister created as children so it could be used by Bonnie Bennett to imprison Kai Parker in a prison world in the final season of The Vampire Diaries.

Legacies will be streaming on Netflix starting Friday, April 5.
