Personally I don't understand how L/P leaving to build a new life together, isn't a realistic reason? It happens all the time. Some best friends....move away later in life. They will always be friends. Maybe even best friends ( we saw that when Lucas returned for Haley ), but they have their own life now...somewhere else, together. I get why people wanted to see their return, but personally I think their exit was handled in a proper way. A realistic way. I'm sad we never saw any goodbye scenes or something, but that's it. Wether people like it or not...distant changes friendships/relationships. If you move..you make new connections/friends, and with L/P...they have their own family now. They will always be contacted with Tree Hill....and they will always share A LOT with the remaining Tree Hill core 3, but they also have their own life. And I love that. I love that they got their happy ending. Leyton fans deserved that, imo. It already sucks for them to have L/P exit the show...and then people just want to let them die ( or one of them ) in sake of the other characters? That's not fair.
