I don't know about anyone else but this is bugging the crap outta me. When we were first introduced to Chalmers he looked at the phone and says, "Who would I want to talk to anyway?". THEN, when he's playing chess he says, "I really need someone to talk to."
So at first they made him seem anti-social, kind of a loner type, then he goes off saying he wants someone to talk to. I don't get it.
