One Tree Hill Clip from "Deep Ocean Vast Sea"

Did Nathan cheat?

That's the question One Tree Hill fans are left to ponder, as we head into next week's episode of the show, titled "Deep Ocean Vast Sea."

According to James Lafferty: "This is a story line that presents a real hurdle, a mountain for [Nathan and Haley] to climb and they have to get through it together. Together they have to carry the whole family unit through the situation, and there's an immense amount of trust. At no point did I actually think it would break them up."

The clip below doesn't deal with this situation, but it is a scene from Monday night's episode:

During the installment:

• Haley ponders taking Nathan’s scandal into her own hands, as his endorsement deals are in trouble; 
• Julian gives Alex another shot;
• Millicent wonders if she can be a model;
• Clay tells Quinn a big secret.

We'll update our site with the latest One Tree Hill music, quotes, photos and more after the episode ends. We hope you enjoy it.
