^ Ah, yes. Quite. Since he was in his cabin I thought for a moment he came from Gitmo, too.
Tex shares his cabin with Lt. Greene so naturally, since Greene takes care of the dog, it calls that cabin home as well.
And yeah, where has the dog been all season? Is the Nathan James so short-staffed they're training the dog to work other areas of the ship? Or do all the crew discuss their personal problems with the dog, like Tex was doing? Is the dog the ship's counselor? Hell, now I'm picturing the TNG bridge, with Chandler in Picard's chair, Slattery in Riker's, and the dog in Deanna Troi's chair.
