Just saw the last episode. That was some good . (SPOILER)The part with Ms. Petrelli and the new company that was epic and Sister Ice's Cold Snap. It's too bad that she died. I was pissed at that, right after she just showed her full potential.
BTW I thought I rememberd from a couple of seasons ago. Isn't Matt Nathan and Peter's brother? I thought I remembered him referring to Ms. Petrelli as his mother.
