The death in the season finale has to be HRG. I love the guy, but he's been aimless since the beginning of vol.4. 1st season he rocked, 2nd he was cool and dark. Vol.3- not so much, he could have just shot sylar in the back of the head and been done with him. his character serves no point other than to be used as a tool by Angela or Claire. It sucks to say this, but he's got to die. How else will Claire grow if her protective father is always holding her hand. His death will force her to become a stronger character. Claire should be the one to kill Sylar or at least hurt him badly. and Season 4 could focus on her role as a company agent who is morally gray, just like her daddy.
Sylar: Dammit!!!
Danko: What?
Sylar: My hands shapeshifted into a towel again!!!
Danko: That happen often?
Sylar: Yeah. Yesterday my penis was a shoe horn for an hour!!!
Danko: oh....
Sylar: What?
Danko: please stop sharing things with me.
