The show is my all time Fav.In episode i am sylar Sylar and his struggle to cope with his newly acquired shape-shifting ability. The episode exploited a much more vulnerable and lost side to Sylar.
personally, Sylar's the main reason I still watched the show instead of droppin out in that god-awful season 3 and i'm glad he's back to bein evil ol sylar again.I'm really itchin to see this Nylar biz in season 4 but i don't think it'll last and i actually have an in-universe xplaination why
Sylar had Regenration
Memory erasing leaves scars or whatever
Heal those scars and you get your memory back
He Heals the scars and BAM sylar's back
even though that will mean Nate will really be dead
