Well I think that they're still lying to Nick about things, I do think something is really wrong with him, but I think that they want to use him for some other purpose. This is why they won't let Nick leave, or let him talk to Lauren. I still think it's not even a real hospital.
I also think Dani is lying that they slept together because she probably wants to keep him there. Lol this story is great, can't wait for more.
