"I once asked him who he wanted standing next to him when all his dreams came true," she says. Brooke obviously has no clue where this conversation is going, but Peyton needs to say this. She needs to hear herself say what her heart won't let her contemplate.
"He said you, Brooke." This seems to surprise her. She's not sure why it surprises Brooke, but it does. It hurts her to think about that day and the way Lucas was so entirely sure that Brooke was who he wanted to be with. It hurt when all she could think of was how much she loved him.
"Why are you telling me this?" Brooke inquires. Why is she telling her this? Why couldn't she just shut up for once and let things be? She settles for the truth. Because I love him. Because he loves you. Because I don't want to fight anymore. Because we used to tell each other everything.
"I would have given anything to hear him say me," Peyton states. Maybe if Brooke understands what she has in Lucas, love, happiness, everything Peyton wishes she had, she won't hurt him anymore. She wants Lucas to be happy, even if it's not with her, even if it's someone else that makes him that way.
