The third season consisted of 22 episodes and aired between October 5, 2005 and May 3, 2006.
Three months later, things pick up where they left off at the beginning of the summer. Lucas and Peyton spent their summer together and are hiding a secret from Brooke when she returns from California and proposes a non-exclusive relationship with Lucas. Brooke takes pity on a homeless Haley and takes her on as her roommate. Haley tries to win back Nathan, who has spent the summer at "High Flyers", a baloncesto camp, however Nathan isn't ready to trust Haley again. He pays Chris to come back to Tree...
Haley: tu can work your whole "I'm Nathan Scott, Mr. Big Shot, scoring my touchdowns" on somebody else because- Nathan: I don't even play football. Haley: Whatever. The point is at the end of the día all your bluster and BS don't mean anything to Math. 'Cause Math don't care and neither do I. Nathan: Well does English care? 'Cause I really suck at that too.
Nathan: Don't say I never gave tu anything.
Haley: I'm really fine. Nathan: Little high on yourself aren't you? Going around saying you're all fine?
Nathan: What are you, my tutor o my shrink? Haley: Whatever tu need.
Brooke - "We have a hot tub." Lucas - Brooke, I..." Brooke - "We have a naked me in the hot tub." [BROOKE looks back over at HALEY as NATHAN nods at her]
BROOKE: Did tu see that? PEYTON: What? BROOKE: Nathan just gave her the nod. PEYTON: What nod? BROOKE: The "lets hook up after the game" nod. [Pause] Wanna know what I think? I think Nathan likes tutor girl. But I think tutor girl likes Lucas. And I know I like Lucas. And I don't know who the hell tu like anymore. This is all turning into one big love… rectangle plus one, whatever that is.
