As I thought, amazing episode. I didn't say this in the last comments but I was think that Micah was Rebel and well I was right, meaning Micah (Noah Grey-Cabey) has a chance of being part of the main characters list again, well since >.< the morons took him out for season three. At the end of the episode Tracey sacrifices herself to save Micah by freezing a whole parking garage including herself. Though you may think she's dead, shattered into a bunch of pieces, she isn't. She says that she has gotten a 'Cold Snap' (Name of episode) meaning she has gained full control over her powers, besides while on the floor in pieces of ice she winks at HRG telling him that she is okay. Also Angela Petrelli almost getting caught is saved by her son, no not Nathan, the other one Peter.
Matt Parkmen's son has the power to bring life to anything, and he ends up bringing part of Hiro's powers back (only the time stopping part). Oh... ya.... and Daphnie died they couldn't stop the infection from the bullet, thats sucks.
