However, it should be noted that everyone (save Peter) in that bomb scene was as we saw them very early on: Claire was dressed as a cheerleader, Matt was a traffic cop, Mohinder was a cabby, etc. So Peter's dream / flashforward might not be an accurate representation of what's to come
Maybe it was going to be an English man, I could be wrong about the new cast member's gender.
Im with Jen with thinking that Nicky took control after Jessica hurt her son and turned herself in. I really love this show.
