Season 2 Edit
Over the summer after Season 1 he begins a romance with Marissa Cooper. Marissa and DJ kept their trysts secret to prevent Marissa's mother Julie Cooper from finding out and firing D.J. When Ryan returns to Newport and asks Marissa if she was seeing anyone, Marissa lies to him and says she's single. However, Ryan discovers the truth when he finds Marissa and D.J. kissing. D.J. is angry with Marissa when he finds out about her lie, saying he felt like a back-up she only came to when Ryan was not around. Marissa apologizes and the two reconcile shortly afterward, with Marissa revealing their relationship to her mother by announcing that as he was her boyfriend, D.J. should appear with them in family portrait photographs to be taken with Caleb Nichol. As expected, this enrages Julie, who felt D.J. was socially beneath her daughter. Arranging a secret meeting with him, Julie gives D.J. a check for $5,000 to leave Marissa. D.J. does so, but first gives the check to Marissa, suggesting she goes on a spending spree. He then leaves her, saying he had no regrets about their relationship, but he feels Marissa was with him less because she liked him, and more because she hated Julie.
