Heroes comment I forgot yesterday
So, when Claire "dies" and there's something keeping her that way (branch in the head, etc) she stays dead until that factor is removed and her body can heal. When Peter gets thrown off the roof and gets a metal pipe through the heart, he pulls himself off the metal pipe and heals. No "stays dead until obstacle is removed."
Plothole, bad writing, or does he just get the special, "improved," version of the power because he's Peter, and therefore, Special?.
Also, Tall, Cynical Boy ended up not taking halfthe week off after all, so I have the next two discs.
