Devon barely manages not to jump. Apparently he's been found. While that does make him slightly uncomfortable, the tone of voice is enough to tell him this guy doesn't intend to cause him harm. Not yet at least.

"I have no idea what you're saying."

He keep his own voice light and friendly just in case Regis doesn't understand him either. The last thing he wants to do is come off as threatening and start a confrontation by accident.
