I liked insight into the Petrelli clan, and Linderman. Linderman actually seems like a decent guy. I know Arthur has to have stolen that telepathic command trick from someone as his primary power is power absorption/stealing-permanent. I'm also curious why the Haitian (he so needs a name, and if I'm told it's Barn LeCroix I'll eat my hat!) is so loyal to Angela.
I can totally see how Elle felt sorry for Sylar and HRG is back as the loyal Company man we recall so well. I can also postulate that after that Assignment, Elle likely got both benched and disciplined (which accounts for ths character's absence until season 2) and also why she's so driven in both Seasons 2 and 3 to catch Sylar... she feels responsible for helping create him as a monster.
I'm wondering why Arthur just killed Utusu. Surely he could steal his power. I'm thinking it's a good thing Ando has no power as he would be a target also.
