In the first episode of season six, the audience discovers that Peyton was on the receiving end of Lucas's phone call. He waits for her and he see's her through the crowd, making her way towards him with bags packed. The two share a kiss, Peyton glowing with happiness. The two board the plane on their way to Las Vegas.
When they get there, they spend the night in a Vegas hotel room. The next day they go to the wedding chapel, however the tackiness of the place convinces them that this was the wrong decision. Instead, Peyton takes Lucas to the hotel room where he first proposed to her and they do it all over again, this time Peyton says "yes."
When Lucas is sleeping he is awakened by his cellphone, and is informed that Quentin Fields has been shot and killed. With the comfort of his friends and family, Lucas finds the strength to address his players and help them learn to cope with this loss.
With the upcoming release of his new book, Lucas travels to New York to meet with Lindsey. He tells Peyton that he wanted to tell Lindsey in person about their engagement. Once there, he is forced to tell Lindsey about his engagement when, during the meeting, he sees that a date in his book tour coincides with his wedding day. Lindsey is visibly upset and tells Lucas that she was right about he and Peyton all along and that he should have just told her over the phone.
