Why i Think Peyton is Lucas's Comet
A Comet comes and goes and so does Peyton

Lucas and Peyton got together and were about to hook up but when he started to talk about serious she LEFT .

Then she realised he was right so she CAME back but he was with brooke , but instead of leaving she decided to get with him anyway and after commiting a series of mistake behind her best friends back she decideds she doesnt want to hurt her anymore so she LEAVES.

As Soon as Brooke and Lucas Broke up she CAME back but that didnt last long when brooke found out the truth so they decided to stay apart and hehe left....
