Hey, I just had an ideea. What if the haitian tried to erase Adam's memory and Adam kinda faked that he lost it... remember the scene with Peter were Adam told him he could recover his memory with his skills (Adam's skills that is). How could Adam know that he can recover memories if he hasn't experienced that himself? That would explain Bob's inocence of putting Peter next to Adam. He must have thought Adam had no recollection of the past. That is one way to put it.
I just love Heroes. It's hard to tell why but I do. Of course I hate some characters. I do hate new Mohinder. He seems so stupid lately, but I do think there is a purpose. I hate Sylar too, but not for himself. I just don't see a good reason behind his actions. I don't think that people are genuinely evil, unless they are deranged, and he doesn't fit either.. he acts evil but doesn't seem loony enough (that didn't come out right). He just wants other people's power/skills. The kid... (after some reflection) He doesn't seem to have a purpose. He gathers the skills for what? He didn't explode, he didn't spread the virus.. It's too petty. At beginning Adam seemed to have that purpose, the love of a woman. But how would that twist him into a mass murderer? And it's Hiro's fault in a way, because he couldn't let go of his childhood fantasies, believing in legends stuff.
But I understand the purpose of the show .. conveying emotions and stuff .. and I'm all for it. I guess that's why I'm so into it.
Its possible they tried the Haitian on Adam, and he learnt he can overcome his "jedi mind tricks"
