Peter Petrelli's scar III

So Peter has a scar across his face, looks like a katana slash, inflicted by a left handed person. Hiro has the katana, and he is right handed. Sylar on the other hand is left handed(??)



Could it be the case that Sylar steals Candice's (the shapeshifter) ability and morphes into Hiro's semblance so that Peter lets his guard down and BAM! ambush??
