Maybe he was interrupted? Oh whatever. I won't even pretend that Mohinder isn't Sylar's BFF 'cause he totally called Mohinder when he was freaking out about exploding.

(And the powers Sylar has? We've seen him steal all of them, actually. He took the telekinesis from the nerdy guy from CSI and the ice powers were taken from someone at the crime scene where we met Matt--the corpsicle with its brain removed was Molly Walker's dad.)
