Lucas "Luke" Danes is the owner of Luke's Diner on Gilmore Girls. Luke starts off as friends with Lorelai but it's obvious he's in love with her and is just unable to express it due to outside circumstances such as Max.
During the season four finale, Lorelai and Luke kiss and they end up dating during much of season five until Christopher comes back intot he picture and marries Lorelai.
During season six, a 12 year old girl, April, arrives at his diner and turns out to be his daughter. During th series finale, it's implied that Luke ends up with Lorelai.
Luke: Me? Raising a kid? I don't even like kids. They're always sticky like they've got jam on their hands. Even if there's no jam in the house, somehow, they've always got jam on their hands! I'm not the right guy to deal with that. I have no patience for jam hands!
Lorelai: First of all, Jess is 17 so I think he's probably pass the jam hands stage by now. Second of all, you can do this. If you want to you are totally capable.
Luke: Coffee, and fries (looks at Rory as she's sipping her coffee). I can't stand it. This is so unhealthy. Rory, please. Put down that cup of coffee. You do not want to grow up to be like your mom.
Rory: Sorry, too late.
