Not sure... he somehow remembered all of us, and it didn't seem like anyone else was strange to him. Ren's the only one he used a different name on, but I don't remember him using anyone else's name yet...
Something's definitely not right... he knows we're in the caves, but thinks we should be on a ship, and he thinks we're all from the same place. And things are making him just kind of... freeze up, I guess. S'weird.
