Sylar snaps his head in the direction of the cell phone, not pained--it's not loud enough--but taken by surprise, this time in a much less pleasant way. He grits his teeth, flicking his fingers at the phone with enough force to stop it ringing as it hits the wall.

And, hopefully, too much of an inconvenience to try and get to, to use against him again.

Turning his attentions back to where she was, he frowns when he notes she's moved, before cocking his head to one side, listening. His ears may still be buzzing from the ring tone, but he can still make out the sound of her breathing. And silently, smirking, he heads in that direction, a hand held out in front of him, just in case she gets the bright idea to try and jump him.
