dont hate me for saying this, but i really hating to see peter with sylar's powers and going completely insane, i mean, its like he completely lost touch with reality by getting this ability, which was not as easy to get by the way,unlike the others. usually peter can copy abilities by being near a person with abilities, but in sylar's case, he had to work in order to gain access to it, i think that was pretty interesting. still, i miss hopeful peter from the previous season, this new psycho one is making me angry. we already have one sylar, we really don't need another one. im sure there issomeplot device in the works here, but i just had to get it off my chest

oh peter, where art thou???

As you predicted they came up with a plot device to rid Peter of "the Hunger". My concern is why it hasn't taken control of Arthur yet.
