I've run into a couple myself.

[ Damn, damn, damn. He hadn't even paused to consider that this wasn't the real thing. That complicates matters, doesn't it? At the very least, this would be one less thing to hold against the real thing - though Rex won't mind holding it against him anyway. He's unreasonable like that. ]

Either way, you may get something useful out of him so all of this wasn't for nothing. I can hold him, but come quickly. Let yourself in. I won't be letting him out of my sight.
