Something had me thinking - way back in S1 in 5YG, Sylar told Claire that Nathan was not who we thought he was before Sylar killed him. Does anyone think that there are set fates, like Nathan is always meant to be President, he's just taking different paths to get there?
I mean, S1 - Nathan's president because of the bomb and the crisis in NY, S3 - Nathan's pres because of everyone being able to have abilities. Each time he's turns out to be not such a nice person, a villian if you will.
Have to say I like that Nathan is turning into a kinda old school style villan.
