Company Man - S1-E17

(Volume Two: Generations) Four Months Later... - S2-E1
Visible crew/equipment: S02E01 "Four Months Later". As the samurai warriors are about to engage the attack, a close-up shot of Hiro turning around reveals the white screen reflected in his glasses.
Visible crew/equipment: When Claire runs away from Bob after he calls her "Ms. Bennet", you can see Bob's shadow and another person's shadow on the ground. Since no one else was standing next to them, it has to be a crew member, most likely a camera man based on the odd shape of the shadow.
Visible crew/equipment: When Mohinder, Sylar, Maya and Molly are at Isaac's old flat (now Mohinder's lab), as Mohinder and Sylar walk down the stairs, you can see the moving camera crane reflected in the glass behind them.
Visible crew/equipment: When Daphne meets Linderman at pine hurst she walks to greet him and you can see a crew member behind a tree on the right side of the screen. (00:42:05)
Chosen answer: It's not been made 100% clear. It was originally assumed that he actually consumed part of the brain, but this has turned out not to be the case. Sylar has been shown all along to have an instinctive knowledge of how things work and how to fix them - this is his actual original power and the ability that made him an exceptional watchmaker and repairer. It appears that he uses a similar process when acquiring new powers - he exposes the brain of the target, allowing him to examine it and determine how their power functions. He can then apply that knowledge to his own brain, allowing him to replicate the ability in question.
