The Mikkaelson family has all been trapped in a magical fascilime of their house. It’s full of memories because Klaus goes the extra mile with a super super super angsty voice over
And it is the whole family because Kol beams in (naked. Alas he doesn’t stay that way) and so does Rebekkah. They’re quickly joined by Freya and Marcel so it’s a whole angsty reunion
This could be one hell of a reality show.
They know a witch is messing with them and originally think it’s Vincent since he’s the only witch who has been around their home long enough to be able to recreate it this way. Except Marcel reveals it’s actually Hope who did this - and she dumped him in there as well when he tried to stop her. Her plan is to put all her family into comas and then pull out the magical darkness that keeps them separate
Flashback: remember the last season with a weird Native American demon girl who was trying to possess Hope for all the evil power. They solved this problem by splitting the Darkness between the whole Mikkaelson family so they could all go their separate ways.
Well last week Hope was determined to make “Always and Forever” (family drama, always and forever”) real again. Despite it being such a very very very bad idea. So she’s taking all that darkness back, which is a really really really really, oh dear gods, really bad idea. The whole of the last season was about stopping this bad idea.
Kol also realises that Hope had help -because one of the rooms in the dream house didn’t actually exist for the last 100 years so Hope couldn’t have seen it. He accuses Freya because he remembers once taking her to that room (wait, wasn’t Freya a prisoner of their evil aunt and the rest basically forgot she existed until about 3 years ago?)
Anyway turns out Freya is helping Hope because she promised and also because she doesn’t think the whole “you lot need to stay apart” thing is ever actually going to happen. Ever. Because they’re all just so completely co-dependent that they’re absolutely incapable of staying apart even if they will literally kill every first born in the city. And finally, since Hope has just lost her mother she can’t possibly lose her dad as well with this enforced magical separation and become an orphan and possibly super emotional and likely to burn the city down because she’s just that powerful and the Mikkaelsons just don’t deal with grief or, well, emotions, in a sane and mature fashion. Ever.
Freya also savagely points out she knows what’s best for Hope, not Klaus, despite his angry demands that his father-ness gives him the power, because he hasn’t been around due to a) curse and b) that time Hope saw him murder people and he decided it was best to freeze her out of his life because he’s just too much of depraved monster angst angst cry angst murder angst cry murder.
Freya leaves him to that and zaps out
So, back to the mystical prison: there’s a door for them to leave but all of them have to find a key to open it. Each of those keys is hidden somewhere significant to Hope and the respective dad, uncle or aunt and will allow lots and lots and lots and lots and oh my gods lots of angst from the most over-emotional family in the world.
