Peter was dead. He'd made sure of it. He'd left the body there, brains open to the air with little pause to mourn the death of his old enemy. He might miss the challenge, and it was a shame to let all of those wonderful abilities go to waste but there had been no safe way to take them on. Not without potentially killing himself.
Sylar had done what needed to be done to ensure his survival. And he would continue to do so. There were others of interest. He wasn't sure if their brains would work the same, but he was eager to find out.
First, however, he needed a new face. Nathan Petrelli had been the perfect choice in fooling Peter. But now that Peter was gone, Nathan didn't mean a whole lot to anyone else.
The Justice League, particularly, was of interest. All of those abilities, for one. For another, if they found out about him they might be likely to try to stop him. Try being the operative word.
After asking around and spending quite a bit of time listening, Sylar had enough information to choose his new face. He chose the face of one who had been here and had disappeared. One who might just gain the trust of those whom he was most interested in. Oh, he was interested in the wizards as well but this face was just another temporary choice. Perhaps he could find out enough to dupe the wizards as well. Eventually, he would find a way to wipe out all of the chosen. And then there would simply be him. Chosen and special and alone, as it was always meant to be.
For now, Sylar had procured a key to Oliver Queen's quarters. He was headed there currently, ready to familiarize himself with the man whose shoes he would be filling for the forseeable future.
