Wilco looks at you. "So... you want some vengence or justice against the real criminals here? That could possibly be arranged, the police like me, I help them a lot, especially with tracking potions." He finishes the potion and labels it, storing it for later. "Sure, the government hates me, but that doesn't mean I can't help the people out. Makes being lonely less boring."
He smiles, he seems to know a lot more then what he's letting on. Some digging could be in order, but he seems friendly enough that you could ask him what his secret is.
