I thought the nurse might have been planning to try and do him in, try being the operative word else wouldn't have been much of a series otherwise unless they found a new baddie, or something twisted like Katie, the babysitter, trying to copy him in some way.
She would undoubtedly help him if he did escape although the police would be on to her like a flash if he did I imagine. She is on bail too isn't she?
Seems more now like she is leaning towards helping him, although who knows what twists are in store.
I also can't make my mind up about whether the memory loss is faked or not.
Only 6 episodes so we are half way through already.
