"You can't ever see one. That's the point. If you see it, it ain't a hidebehind no more."
"So, what, being seen kills them?"
"Naw. By definition, if you seen somethin' weird, you ain't seen a hidebehind. That's logic. Might kill 'em, I s'pose."
"What about mirrors? Three-hundred-sixty-degree cameras? Satellites?"
"Yer gettin' fancy now. If I was a hidebehind, I'd be pissed off right now."
"You're not, though. I can see you."
"Don't mean there ain't one behind me. Or you. Hell, they could be all around us, we'd never know."
"Yeah, I'm wishin' I hadn't said it, too."
