His dream showed me that no matter what Naley and Keith&Karen would be together, one way or another.
LPrers don't kill me for saying this, it's my opinion, and I could be totaly wrong, but as a BLer I can hope, right?
We also saw LP failing in their relationship, like they couldn't work it out. Yes, it was because Luke was a jerk and they were supposed to portray NP, but we didn't see Lucas falling for Haley but Nathan. I just found it kinda weird that since the "meant to be" couples [NH&KK] found their way, LP hasn't, just gave me BL hope that LP aren't meant to be. Like I said, it was my opinion at the time, too much changed after that season to actually consider it as a reason why LP won't end up together now.
