Scout looked the man up and down in silence for nearly a full minute. So he was supposed to just go at the lone man, hm? There had to be some kind of catch. And it wasn't as if Scout actually wanted to kill anyone. That would be one hell of thing to live with. Unaware of the other man's thoughts - about Boo, about him - he quirked an eyebrow, and with his arms still crossed, he asked:
"First tell me: what's your power?"
Though man might have known Boo, Scout had no idea who the person in front of him was, besides an obvious psycho. He smirked.
