I'm all for Maya and Mohinder (especially Maya) taking vengeance on Sylar, but not necessarily of the killing-off type. Not that I expect Sylar to be on the show forever, but honestly, if/when he gets offed, I'll probably stop watching. He's by far the most interesting character in my book. And I don't really understand the viewpoint that having the same villain for a long time automatically has to be boring. Sure, it would be boring if he just keeps doing the same thing over and over, but I personally would much rather see one villain who grows and develops and changes over time, rather than just a bunch of one-and-done villains who show up, do something evil, and then predictably get offed. That would be a yawner to me.
