^ you bring up some interesting points bethy...they might need closure. I just think Lucas and Peyton ending up together would make look Lucas like a wimp and a total flipflop...and he doesn't deserve that. Neither does Peyton deserves to be second choice, if he truly loved her, his eyes would've opened when Lindsey left. But he's not taking the easy road right now, so unless something really bad happens to Linds, I hope he stays put this time.
On the writers-block issue: I think it's fairly logical he regains insparation from both Peyton AND Brooke returning to Tree Hill, his father coming out of jail... And I just haven't seen the return of Peyton "giving meaning" to Lucas' life.
