There's no Major League Baseball playoff game on tonight; nor is there even a new episode of House.

Therefore, viewers have no excuse not to tune in to "I and Love and You," a new hour of One Tree Hill that producer Mark Schwahn refers to as an emotional turning point for the show.

The installment will delve deeply into Clay's background, as fans will meet a woman named Sara.

Also, the Nathan love-child storyline will remain a focus when Renee is featured on Dan's talk show. Star James Lafferty even directs the episode.

Check out Schwahn's preview of the "I and Love and You" below:
