In last night's season finale of The Vampire Diaries, oodles of characters died and crossed over to the Other Side, to be eventually resurrected by Bonnie. (Well, not everyone. R.I.P. Damon?) With all the insanity that went down in those final minutes, it was easy to forget the moment that could have the biggest effect on Season 6: Tyler's realization that he is no longer a hybrid. Does this mean that everyone who came back from the Other Side is now human? We speculate below.

No, Tyler was special because he had a Passenger. Tyler's death and resurrection was a bit different from the other characters who died and came back. Unlike the others, he was first banished from his body by Passenger Julian. Then, Julian was killed, along with Tyler's body. When his body died, Tyler's spirit found its way to the Other Side. Did this distinction — Tyler's body banishment — effect Tyler's return? Also unlike the others, his supernatural body went through the complete reversion when Julian was forced into the magic-less Mystic Falls. We had to watch Tyler's body work backwards through his werewolf turn, death, and vampire transition. Brutal, but also potentially important. Is this why Tyler came back as a human?

Another argument in support of this particular theory is the fact that none of the others seemed to notice a change after their return from supernatural purgatory. We know there was a lot going on, but you'd think one of the others would have made the observation that they were feeling less tangy than usual, no? Perhaps, Tyler is the only one who has reverted to his human — or, at least, werewolf — state?

Yes. they are all human again. On the other hand, this might be a genius re-set for this show that has more-or-less made all of its characters into invincible vampires. If Elena, Stefan, Tyler, and Enzo are all human again, then the show can have them asking some interesting questions about what they want for their futures and how this changes them as characters. Elena, for one, never wanted to turn into a vampire (not to mention it was her transition into vampirism that coincided with her falling in love with Damon).

Let's face it: Stefan has always been a terrible vampire. And Enzo is probably going to be way less murdery as a mere mortal, no? This could also play into the "reclaiming our home" storyline teased on the promo poster for Season 6. As was mused on by Matt in the Season 5 finale, just because the fang gang defeated the Travelers doesn't mean their spell preventing magic in Mystic Falls will end. If this is the case, then TVD is going to need some characters who can actually enter the Mystic Falls town limits. Turning more-or-less half of its cast back into humans could make this potential storyline much easier and more interesting to explore.
