The extended promo for next week’s episode of The Vampire Diaries introduces the dilemma that someone killed Enzo’s girlfriend back in the 1960s, and that Enzo wants to kill someone for it. He seems to think Stefan was the murderer in question, but the promo implies that it was really Damon. What the heck happened in the 1960s? Who killed Maggie?

Damon. Let’s face it: when there’s murdering on this show, Damon is usually the one behind it. In the promo for next week’s episode, we see Damon rush into the Mystic Grill just as Enzo is about to rip Stefan’s heart out. “The thing is: Stefan was right. He didn’t kill Enzo’s girl…” Damon begins, and we can’t be the only ones expecting him to finish that sentence with “I did.” Damon is also the only other character who has any feasible reason for interacting with Maggie, given that Enzo had told him about her when they were cellmates at the Augustine Society. Did Damon seek Maggie out after leaving Enzo to presumably die in the Augustine fire as a way of making amends for what he thought was his friend’s death? In finding her, did something go terribly wrong, resulting in Maggie’s death? We really hope this isn’t the case — Damon needs a win right now — but we wouldn’t put it past the emotionally volatile vamp.

Stefan. There has to be a reason Enzo thinks Stefan is responsible for the death of his one true love, right? And it must be at least somewhat convincing to get Enzo to go after his bestie’s brother. It’s not like Enzo has any backup friends to hang with once Enzo kills Stefan and Damon returns his half of their broken-heart friendship necklace (because we all know this exists). Might Stefan have been in another one of his Ripper phases, killing Maggie in one of his bloodlust frenzies? We had thought that Stefan had his urges under control in the 1960s, but we don’t know for sure. Could he have slipped, resulting in Maggie’s death? Or, perhaps, he had legitimate reason to kill her. Maggie did work for the Augustine Society. Enzo seemed to think she didn’t know the extent of the torture, leaving when it was revealed to her, but we’re not so sure, especially given that the Augustine Society obviously survived following the fire. Was Maggie actually the mastermind behind the operation? Was she trying to kidnap Stefan when he killed her?

She’s not dead. The introduction of Maggie as a character has always seemed suspicious to us. From the first time Enzo told her story, we’ve felt like she would play a role in the series that warranted her backstory and even naming. She isn’t important just because Enzo loves her, but because she plays a bigger part in the mythology. We think Maggie might have more power than Enzo ever imagined. We think she might be a Traveler, planted inside of the Augustine Society to find the doppelgangers. We think she is still alive, perhaps as a Passenger. It’s not like TVD hasn’t used this twist before. Damon loved Katherine for years and did everything he could to save her from century-long entombment, only to discover that she had never been entombed at all. She had saved herself, and had been living her life without him. Will the same thing happen to Enzo? Will he discover that he was just a pawn in Maggie’s machinations?

What do you think happened to Maggie? Do you think she died in the 1960s? If so, who killed her? Sound off in the comments below!
