1. Sylar is able to get powers from the people he kills...how does he get those power...I know he cuts the top of the head off..but from there how do those powers get to him, because Peter can just absorb them WITHOUT killing..by just being close to the other people.... So if Sylar absorbs powers like Peter why does he have to expose the Brain?
2. Peter can absorb powers by just being next to somebody... so when he was fighting Sylar both at the High School and in Mohinder's apartment Why did he not absorb Sylar's powers when Sylar was under the impression that he could absorb Peter's by slicing off his scalp?
1. Sylar does not absorb powers like Peter. Sylar's base power is Intuitive Aptitude, or the ability to see how things work, so he sees how the powers should work in himself. It has not been revealed yet how Sylar gets the powers once he cuts the brain open. It was theorized a while back that he ate the brains, but I don't believe it.
2. Peter more then likely did absorb all of Sylars powers he had during their two encounters, he just hasn't displayed any of them yet. Well, except Ted's Radioactivity.
