If you haven't seen the movie, stop reading unless you want us to spoil the movie for you.
Okay, if you've seen the movie, how do you think it ends?
I figure she wakes up, but she's tied to the bed with restraints, as seen in an earlier shot and as no one knows where she is, unless a neighbour hears something, she starves to death.
Bleak but I don't think she's just waking up, having a shower and grabbing a coffee.
What a stupid question.
It ends just like all other movies with credits.
If she couldn't get out of the restraints in the apartment, I think she'd probably scream until one of her neighbours called the cops and/or the superintendent. It wouldn't end in her death in the apartment.
Although, finding a completely restrained woman in an apartment next to a corpse (would it even have a scratch on it?) would be a crazy mystery that the cops wouldn't let go.
Frankly, I think there's a super-interesting sequel possibility of the investigation around Jack's death while Alice tries to bring down Victory. Plus, we get one of the most interesting details right at the end: Bunny *wants* to be there (is her husband the one who's restrained, or are they both their voluntarily?) and Alice trying to knock down Victory would be diametrically opposed to Bunny's desires.
