One Tree Hill made viewers smile last night, airing a penultimate episode that was surprisingly light and happy.

But why do we have a feeling that the tears will be flowing next Wednesday evening?

Probably because One Tree Hill will sign off after nine seasons following an episode aptly, simply titled... "One Tree Hill." The official CW description teases a "final chapter" that will mark the 10th anniversary of Tric and bring with it "old faces and new possibilities for the Tree Hill family."

Prepare to cry. A lot. And watch the first trailer for this finale now:
