After revealing his undead status to the Mikaelsons — and murking every last Strix member — Marcel gave Elijah and Kol his one-of-a-kind love bite; as if that wasn’t bad enough, Freya was also poisoned. A desperate Hayley woke a still-hexed Rebekah from her slumber in an attempt to quell Marcel’s rage, but the irreversible damage had already been done.

Freya was able to prolong the gang’s collective existence by daggering them and tethering their lives to Klaus, who went on trial for his many, many, many (just assume this goes on for a few more pages) sins. Given that his jury was literally full of his enemies, it should come as no surprise that he ended up with Papa Tunde’s blade embedded within him by the end of the mistrial.

Season 3 came to a close with Hayley and Hope carting their caravan of bodies out of New Orleans in search of a cure. And now, it’s time for some answers…

TVLINE | I assume Hayley won’t be able to save everyone on her own. Who might she turn to for help?
There were hints in the finale of what Hayley’s next move is going to be. I don’t want to say too much, but I don’t think it’s outside the realm of possibility that Hayley will look to find a way — either by using her own vampire power or by using a witch — to try to communicate with [everyone in the dream world]. She has a giant puzzle to figure out in order to cure everyone, and given that they’re dying from a wolf bite, I think you can guess who she might turn to.

TVLINE | Given the hectic nature of the episode, do you foresee a time jump next season?
It’s almost mandatory that there be some sort of time jump. This is a definitive loss on the part of the Mikaelsons. The prophecy predicted they would fall, and they fell. There’s no easy way out of the situation they’re in. Hayley and Marcel are both going to have to start from scratch as he decides how he’s going to deal all these new vampires in town. There’s going to be a lot of story to tell, but I think we’ve painted ourselves into an unbelievable corner, and it’s going to be great fun to get out of this situation.

TVLINE | Lastly, just out of curiosity: What do you think Hope’s first word(s) will be?
[Laughs] I can’t imagine. One question is: Are we, as an audience, going to get to see those first words? If there’s a time jump, maybe not. But given everything that’s happened, and how the Mikaelson family has been so completely deconstructed, Hope is left with no one but Hayley. I’m sure her first word will be “mama.” It’s the person who’s taking care of her right now, it’s got to be “mama.”
