If the girl is around 10 or 11, that probably means that he met/knew her mother around the time that Rachel left? Is my math right? (Its hard to know in Gilmore land.) I doubt they'll even think of that or have it play into it at all, but that would be interesting.

Poor Luke, he's going to be kicking himself if this is really his kid. Yeah, so, I'm a little excited now. Thanks guys.
