oh, I am relieved that they are coming back. I coudn't imagine Heroes without them.

I don't know about regrowing from pieces. When Ted was glowing in Claires's house, he wasn't affected. So Peter does not necessary explode himself into pieces, but surely he must be affected by the radioactive fallout, but he will heal instantly. Interesting though, if there would be multi-Peter.

I wonder if Peter also emits an high EMP (electromagnetic Pulse) as an nuclear bomb in the atmosphere would. That would affect all electronic equipment in New York. (That scenario was used also in Stargate Atlantis, The Hot Zone)

I wonder if Claude was doing something. Sometimes I got the feeling he was there invisible.
