He's one of the few characters in the game that actually has an interesting personality. He's not just some drone that spews out pointless, meaningless dialogue. Almost every line he has gives you insight into the kind of character he is, instead of just boring generic dialogue like you get from most characters. "I've got to get out of this Tower and back out there." "Alright, I'll be right here...like it or not." "Hey... *whispers* take me with you!"
