If you think Luke and Lorelai were destined from the start, you aren't exactly right. The Gilmore Girls creative team, Amy Sherman-Palladino and Daniel Palladino, told Entertainment Weekly that Luke was originally a female character named Daisy.
The network "came to me and said we need another guy, so I literally just took a character and changed the name, didn’t even change any of the dialogue because I’m that lazy," Sheman-Palladino said.
Lorelai and Luke weren't supposed to be together—they just had undeniable chemistry. “It was the episode where they were in the market and Lorelai’s spying on Dean," she said. "Luke was there and they had this scene that didn’t mean anything.”
With Lauren Graham and Scott Patterson ~feeling each other~, it's not surprising they ended up together. "It was just something about the two of those characters together that they kept going back to and then it kept growing," she said.
Patterson also knew the chemistry was there. “You just never know about that kind of thing," he said. "You can get the two most talented people in the world together on screen, and for some reason, it just doesn’t work. I knew it from the moment we met, and I knew it was going to work on screen. We just had a rhythm.”
We're happy it ended up the way it did.
