Alright, I saw this in theatres, so I haven't been able to check it, but I'm pretty sure it'a a slipup.

DO NOT READ FURTHER IF YOU HAVE NOT SEEN THE MOVIE!

David and Teddy are in the ship thing after Joe got grabbed. When they are going down to Disneyland, in one scene (before we know what he's heading for) we get a good view of the front of the ship, but there's NO TEDDY! At least, I think so. Maybe he was really dark and it was hard to see, or partially cutoff, but that angle I was looking for him because he hadn't spoken in awhile. Check it out, and tell me if I'm wrong.
