David Bridgewater

In the fourth season premiere, the aftermath of the post-wedding car accident unfolds. While Haley is deeply affected by Nathan's attempt to rescue his uncle Cooper and Rachel Gattina from the underwater wreck, Brooke confronts Lucas with her true feelings, and Peyton makes a startling discovery. Also, pressured by the thought that someone knows he killed his brother, Dan assaults Deb.

As the lives of Nathan, Rachel and Cooper remain turbulent following the car accident, Brooke celebrates her 18th birthday, but finds it diminished by her struggles with Peyton. Elsewhere, Lucas and Karen come to terms with her pregnancy and that of someone else close to Lucas, and Haley becomes aware of Deb's past addictions.
