CHRISTIAN: Maybe fate has just thrown the 2 of us together, you know. Two drinks in an airport bar -- ANA: Why would fate do that? CHRISTIAN: Same reason fate does anything -- so that we can help each other out. You do need help, right? Unless you don't. What I'm doing down there could be a little dangerous and I need someone to protect me -- a bodyguard. It's perfect for someone who stopped being a cop. And of course his much quoted lines "Say hello to my son!" * Although we see Locke already has this idea in his head the "origin" or this idea comes from Christian.
