This fic takes place at the beginning of the episode in Season 1, "Christopher Returns". It's another way to get Luke and Lorelai together.
"I do not believe that your mother and Luke are in a relationship. I don't believe that they are dating, whatever," Chris said. "Prove it. Kiss. If you're really in a relationship your kiss will be real. And not like that short kiss you had over at the counter. A real kiss. I want you to prove it. Because, Lorelai, I want you. I want you to want me, too. But if you're with someone, then I don't want to wreck it. So kiss."
Lorelai, Luke, and Rory just stared at Christopher. "Are you going to do it or not? Because if not, then, Luke," Chris turned toward Luke, "I'm going to take her, whether she likes it or not." Lorelai's eyes opened wide in fear.
Luke put the food he was holding down on the table. He took Lorelai's hand and stood her up. He walked her to the middle of the diner. She looked into his eyes and saw something that had never been there before, or something that she had never seen.
Luke put his hands on both of Lorelai's cheeks, and brought her up to his lips, though leaning down a bit himself. Lorelai could not believe how great a kisser he was. His lips were so soft; he was just—perfect.
Oh . . .my . . .god. Luke is an amazing kisser. And, oh god, I want this, too. I want this more than anything. I want to be with Luke.
Lorelai started to kiss him back. She could almost feel the relief coming out of Luke that she wanted this as much as he did. And the town was right. They did want to be together; they were perfect for each other.
Christopher watched their kiss, and his heart broke. It was there—the kiss was filled with love and passion. Lorelai was going to get the whole package, but it wasn't with Chris. It was with Luke. Luke was basically Rory's dad. Chris had never been there; it was always Luke.
Lorelai and Luke finally broke away from each other. Luke leaned his forehead against Lorelai's and smiled at her. She returned the smile, and as soon as she did the entire diner burst into applause. Everyone was in there—Sookie, Jackson, Ms. Patty, Babette, Morey, Taylor, Andrew, Gypsy, Kirk, everyone. And anyone who was not inside applauding was doing it outside of the diner. Everyone was smiling and shouting things like, "Finally!" and "See we knew it!" Lorelai's hands were around Luke's neck, and she was playing with his hair.
Suddenly, Luke took of his hat and put it backward on Lorelai's head. Her face broke out into a huge grin, and she kissed him again. Once again the diner burst into applause.
Chris stood up and whispered into Rory's ear, who was clapping harder than anyone else, "I'll meet you at home, kid." Rory ignored her father, and jumped up to congratulate her mom and Luke. She was ecstatic that her "real" parents had finally gotten together. And she didn't care that Chris hadn't believed them.
