Did you watch the video when she kills herself? I think it is pretty clear that she is dead. How did "she" unlock doors? I do not have a satisfactory answer.

The only thing I can think you is the marker animating her, like a zombie,

 

 

Yeah, but there is no mention of zombies in the game...at least, zombies who look entirely alive and whole. Maybe Kendra was unlocking the door but Issac imagined it to be Nicole?
