"...Yes, I am." Well, he was going to introduce himself, but it seems that's not necessary. He steps over into the room, wiping his hand off on his shirt as he goes. He's a little uncomfortable that he's been recognized. He looks over the metal walls as he goes, feeling more on guard now that he's recognizable in this place.

When he gets close enough, he offers his hand for a shake. Whoever he is, this person doesn't seem like he's doing very well (who would, in a place like this?), but he's going to need his help if he's going to get to the bottom of this. "This may seem a strange question, but could you tell me where I am? What is this place?"
