You've been warned!
Here comes...
Is Chris's name actually a serial number? He says it's too long to reasonably spell or pronounce, but doesn't (as far as I can tell) give any other hints.
We can guess that's he's some sort of clone or test-tube baby. His father never seems to particularly care for him, so it's possible he was never given a family name.
I'm not sure there's any other evidence for this, but I can't think why else he keeps mentioning that he isn't going to tell his name.
