Aye. Having nookie will do that sometimes. He hooked up with some chippie early on and had a kid, though he didn't know it for a long while.
Did he ever find his girlfriend?
Yes, but he realized that he was in love with 355 an issue later.
What the hell is he in prison for?
He tried to kill himself, so his daughter, who in the last ish is now President of France, had him locked away and put in a straight jacket to protect him from himself.
