Oh. He's from space. Well, why not. John keeps his emotions in tight check, but his eyebrows do raise at hearing that. "Yeah. This is a dog." He replies. He looks down at the dog, the dog looks up at him. "Sort of a pet. We fell in together a few months back. He's...good company. Ended up here with me." Not going to argue with that.

"He's friendly." John adds. The man seems curious, but hesitant, so if he wants to come investigate, John doesn't mind. No reason to suspect this one's any sort of threat.
