Yep, that's where he figured it was going. Peter's Look became pained, as well as exasperated.

"I can't do that. We don't know what it is- it could trip something and blow up as soon as I touch it. You'd come back and I wouldn't. Or maybe neither of us would. And I don't have your aptitude. How am I even supposed to find it? What if I hit your kill spot?"

Ah...whoops. Peter stopped and looked around. His voice had raised to the point that he was starting to attract attention. He sighed heavily and stepped closer to Sylar. His voice lowered, but it was no less intense.

"Sylar, the only time- the only time- I ever tried to kill someone, I did it like that." His brother and then his mother. "We have to find another way. ...you said people had seen this place? We should go take a look for ourselves."

Because that was less dangerous, surely.
