I'm assuming after chapter 3, Mr Bennet is an early Sylar and has eaten some of claire's brain. (if that's how he obtains others' powers). She regenerates and no harm is done to his daughter.
i think sylar is the future version of claire's creepy father. HRG (aka mr bennet) already met Chandra Suresh and is aware of the map and his research. And he possibly already has a copy of Chandra Suresh's book. So he presently knows where to find some of heroes. And might have killed Chandra Suresh
His first encounter with another hero is Nikki and Hiro. Why? Hiro already can see the future with the help of his comic book, is currently on his way to las vegas where nikki lives. It is shown that Sylar has Nikki's doppelganger powers because his apartment was magically cleaned like Nikki's garage. So if Sylar is the future version of Mr Bennet, than Mr Bennet will seek out Nikki. He will encounter Hiro because it is his destiny to save nikki from mr lindenburg. Mr Bennet will probably eat her brain and her son's brain (Micah might have telekinesis, which i'll explain later). Hiro tries to rescue her but is unsuccessful. Hiro can't hurt Mr Bennet (now sylar) because of his indestructability, and Sylar's Doppelganger kills Hiro just like Nikki's doppelganger killed mr lindenburg's henchmen. He probably finds her husband and kills him too. DL has phasing powers
Sylar can now teleport and travel threw time (maybe phase). He goes back in space and time to get help from Chandra Suresh. Suresh discovers his powers and tries to not help Sylar, whom ends up murdering him (as maybe revealed in the tape recording). Sylar wants to find more heroes so he trashes the apartment and was unsuccessful and teleports to his home in india to find more answers. He finds what he's looking for, turns around and Mohinder vanished with his research. He goes back to new york and meets mohinder in the cab. He doesnt kill him cuz he wants mohinder to finish the map. Mohinder eventually does complete the map.
Sylar travels to the future and makes a copy of the map. He also witnessed armageddon and goes back in time possibly to fix it. Sylar's mistakes may also trigger armageddon. while in the future he visits Isaac's studio and takes his brains (because sylar now has the comic book), he also sees his paintings of nathan and peter. He finds them and takes their brain. He also sees paintings of all the other heroes (officer matt parkman). He cant stay in the future cuz it's gonna end. So he goes back in time.
He finds a connection to the little girl through the paintings and comic book (possibly claires biological sister, since it could take weeks to find claires birthparents, sylar uses time travel to shorten the wait). She is a major role in the plot, but i just can't figure it out. He tries to find her and is unsuccessful. Matt finds her via telepathy and is sent to the fbi for safe keeping.
Now if Mr Bennet was an fbi agent, he probably goes the fbi place to find her. His occupation is currently unknown. This is a possible link to his occupation, there are many.
Remember sylar has peter's temporary power mimicry. It is also revealed that he has telekinetic powers because of how he killed the girl's parents (look at the mother's death, and isaac's too). So we might know Micah's secret powers, if he has any (sylar had to get telekinesis from someone?). As he is shot from officer Parkman's gun he temporarely mimics Parkmand telepathy. He is unharmed from the bullets and teleports, flies, or phases out of the scene.
Sylar meets Parkman again at the bar. Parkman cannot read one persons mind. This is possibly a new character. This one might be the antoganist that destroys the world. Sylar knows he has to defeat this new guy.
I assume "the new guy" has extreme powers like Jean Grey/pheonix from xmen.
And i could be totally wrong, but i made a feasable plot line.
