Answer: Keith
Nathan panicked under water, and was sure he saw Keith. He didn't share this information right away, but eventually did tell Luke. Luke told Peyton, and somehow Rachel found out as well. Nathan did tell Haley, but not until a few episodes into the season. Rachel had become too interested in Nathan at this point, and was using all things to her advantage to manipulate him.

Answer: Derek
Peyton finds a letter in one of the albums Ellie left her saying Peyton has a brother. Peyton and Derek share the same biological father but have different mothers.
From Quiz: Tree Hill High Season 4
Answer: Derek
Peyton discovered this when a piece of paper came out of one of Ellie's Led Zeppelin albums. She first told Luke, and I was hoping her brother would be Mouth, but it was Derek. I am not sure what the paper could have said, unless it was a note from her real dad to Ellie, and it talked about his own child. When she finally worked up the courage to call him, whomever she spoke to told her never to call back. Not too longer after this, Derek appeared on her doorstep, or so she thought...
Matt Barr played psycho Derek in seven episodes of season four.

Answer: Lucas
Brooke allowed people to think she was pregnant instead of Haley. She did try to say that she wasn't pregnant, but she didn't protest too hard when people pried even further. Rachel was so convinced it was Brooke, she gave her pamphlets and told the news to some folks. Mouth overheard the girls fighting about it after Rachel's party, and told Brooke he thought she'd make a great mother. Haley, petrified to tell Nathan, told Luke that it was her, not Brooke, who was pregnant. Luke had come to the conclusion a bit earlier that Brooke was pregnant, but Chris Keller was the father.

Answer: Lucas
Nathan told Lucas, at the river court, that he was planning to throw the game to save himself from Daunte. Lucas told Skills that they would have to freeze Nathan out of the game in order to save it. The first half ended in a fight between Nathan and Skills on the court, with the score 36-21 Pontiac. During their half time, Whitey played them the radio announcers broadcast from the game Dan lost the Ravens 18 years prior. He admitted that he hadn't imagined at that time he would only have once chance to erase the feeling that night had left him with. This changed Nathan's perspective and he came out in the second half full of energy. In the final seconds of the game, Nathan passed the ball off to Skills, Skills passed it back to Nathan and Nathan sent it to Lucas on the outside. Lucas hit a buzzer beater three pointer to win by one point. Lucas had forgone taking his HCM medicine for that one night, just to make sure he could compensate for Nathan's bad play. It was a mistake.

Answer: "It's Tricky" by RUN DMC
At the last moment, Skills chickened out and Mouth had to go onstage with Nathan. The song is so catchy, that alone could have won the competition. But, the boys took it off with enthusiasm as well, and Bevin coaxed Skills into the dance for that last minute. Nathan wanted quick cash for a maternity prom dress for Haley to wear. While I find that to be sweet, as pending teen parents that money could have been better spent.

Answer: Brooke
Peyton told Luke that she wasn't going to Prom. Luke said he would come to get her, but if she still said she wasn't going that he would go alone. When Brooke found out that Peyton wasn't coming to the dance, she went to her house looking for her. The crazed man held Brooke and Peyton in Peyton's basement until she changed her tactic. She acted as though she wanted to kill Brooke (for revenge) and that she did want to be with him. He gave her his knife, albeit hesitantly, and she used it on him. He chased her upstairs and Peyton boxed him around her room. When he finally overpowered her again, Brooke came in and hit him with a walking cane. A huge fight ensued and the duo sent psycho Derek down the Sawyer staircase. He was later taken away by ambulance.

Mouth was happy to see his friends arrive to get him out of jail, but he kept saying his reason for being there was "a long story". He finally revealed most of it to one of them, but revealed his reason for arrest to most of them at one time. He told Chris Keller that Rachel had made him feel really special, but that the whole time he really did know they were a lie. It was when she used the same line on another guy, that Mouth knew it was time to go home. He told her that, and she split without saying goodbye. She left him a picture of the two of them that read on the back "I could have loved the boy in that picture". This was a similar statement he'd said to her about her overweight photo.

This is where Brooke finally revealed to Haley that she was the one who stole the test, and not Rachel who'd confessed.
