last time ended with TOm being put int he box, his wife chained in back of van and driven to institute place by guy who was supposed to be his mate.
Anyway turns out Tom's claustrophobic (which friend guy knew). It went back to when Tom first met Claire (his wife) and when he first turned into Hyde. Stress set it off and he kept seeing someone else's reflection with his and then saw Hyde in mirror.
Thought he was losing it as was writing things he couldn't remember (I am coming) and hearing things that noone else could hear etc.
Also saw the first time he got the flat and the first time he recorded Hyde on video (was really freaky).
Then PI (Meera Syal) and her girlfriend and Tom's nurse turn up outside the institute place. She rings ex-friend guy, and his girlfriend (the secretary he was shagging) and all the other women in the room he had shagged (basically all of them) and got quite complicated as she was talking to him on many different phones at once (to freak him out).She said she knew about WInston Churchhill.
