What to expect from characters in S4?

I expect a great flash back episode from Millie and Angela

Good idea. They are saying Millie's daughter is important and that they will do stuff on it and they'll also do stuff on the forming of the Company.

I just hope Hiro lives.

oh you read the spolier i know

There must be some way of healing him... The writers won't use Claire's blood again and they didn't for Nathan, but surely the characters must've thought of that? So how can the writers make them forget this?
