SON BY BLOOD – Harry (Rob Estes) and Debbie (Lori Loughlin) inform Annie (Shenae Grimes) and Dixon (Tristan Wilds) about Harry's son that was given up for adoption nearly 22 years ago. While Dixon doesn't seem bothered by the information, Annie releases her frustration and anger at a sleepover with Naomi (AnnaLynne McCord), Silver (Jessica Stroup) and Adrianna (Jessica Lowndes). The sleepover quickly turns into a house party with guys and drinking games.
Meanwhile, Annie and Ethan (Dustin Milligan) decide to hide their relationship from their friends and Dixon opens up to Silver (Jessica Stroup) about his latest family issues. Adrianna and Navid (Michael Steger) continue to get close until she misunderstands his intentions. Now that Ryan (Ryan Eggold) is in on Kimberly's (guest star Jessica Lucas) secret, the two can no longer control their desire for each other but are oblivious when a student observes their actions.
Harry and Debbie sit down their children for a talk. Harry tells Annie and Dixon that in high school he dated Tracy Clark. He says that Tracy got pregnant, but they decided to break up. They agreed to not have the baby and he went off to college. He tells his kids that he learned two months ago that instead of not having the baby, Tracy had a son and gave him up for adoption. Tracy has hired a private investigator to try to find her son. Harry tells Annie and Dixon that he hopes that their new half-brother will not affect their family in any way. Dixon and Annie are shocked by the news. They head off to school.
Dixon and Annie pull up to the school parking lot. Annie is very upset about her dad's revelation. She calls him a hypocrite for having sex and fathering a kid while he was so young. Dixon tells her that she should cut him some slack. Dixon says that it is freaky, but he is cool with it. Annie lets Ethan in on the news. She tells him that it is weird that Naomi and her now share a half-brother. Annie tells him that her relationship with Naomi is becoming more complicated. She says that she is at a fork in the road where she has to make a choice between Ethan or Naomi. Ethan tells her that they should keep their relationship on the down low. She agrees. Ethan and Annie plan to meet after school.
Silver approaches Annie and tells her that Dixon filled her in. She invites Annie to come over to her house for a slumber party before Kelly comes back home. Adriana returns to school and finds that everyone is staring at her. Navid approaches and compliments her on her clothes. He gives her a bag of jelly beans as a gift. Adriana tells him that she likes the popcorn flavored beans, takes one and gives the bag back. Naomi arrives at school and tells Annie that she just learned about her mom's son that morning. She invites Annie to go shoe shopping with her after school. Annie panics because of her date with Ethan. She lies to her by saying that she has no plans and agrees to go shopping. Later, Annie tells Ethan about having to go out with Naomi. Ethan tells Annie that she should practice lying to Naomi. In the hallway, Silver tells Annie that she invited Adriana to her slumber party. Naomi approaches them and is also invited. Naomi tells them that now that Annie is like a sister, they should hang out more often.During break, Silver gets Dixon to open up about learning that his adopted dad has a son. He tells her that he was thinking about a person out there who has the same laugh as Harry. Silver asks him about his adoption situation. He says that he lived with his grandma in New York for a while, but his father was never around. After his grandma died he lived with his mom in Kansas. She was crazy and wouldn't take her meds so social services took him away and placed him with the Wilsons. He tells Silver that he is happy with his current situation. Dixon says that he appreciates where he lives at now and his girlfriend. Kim, the police officer posing as a student, meets with Ryan before class. He tells her that it is getting harder to see her everyday after school. The rest of the students come in and they pretend to be having a conversation about school work.

Adriana tells her that she has been ordered to attend meetings after school because of her drug use. Naomi tells her to show up at the slumber party saying that they are going to do more than drink.

Naomi tells her that Navid wants something from her. They see Ozzie who asks Naomi what she is doing later. Naomi blows him off and Adriana tells her that she is going to drive Ozzie crazy.
At home, Harry asks Annie about unusual credit card activity. Annie tells him that she bought some boots. He tells her that the card was for emergencies only and that her shoes cost more than some small cars. Harry sees that she is packing and asks where she is going. Annie tells him that she is going to a slumber party at Silver's. Harry knows that Kelly is not home to supervise and tells her that she is not allowed to go. Annie gets mad at Harry saying that when he was his age, he was making babies. Harry tells her that she has to return the shoes too.
After her meeting, Adriana finds Navid waiting for her. Adriana accuses him of stalking her. Navid tells her that he wanted to take her out to eat and that she owes him for the jelly beans.

Opening Tagline: Silver
- Annie – (to Harry) No. No, I'm not okay. And it's your fault. I'm not okay with you having a son. I'm not okay that you kept him a secret for months. And I know... I know that you didn't want it to work like this, but it affected me. And you weren't honest. For two months you were a liar, and now I have to be honest. And I have to tell you that it made me so mad at you for not being honest. Because secrets... they just make me feel so sick and wobbly. And everything's a big mess now. And I have vomit boots!
- Annie – (imitating Harry) "I'm really hoping that this doesn't affect us in any way." It's like, what did he do? Did he practice last night in front of a mirror? Like, really?
- Dixon – Maybe he was, you know, nervous about it or something, you know?
- Annie – Yeah. He had about two months to prepare for it
- Dixon – Come on, cut the guy a little bit of slack
- Annie – Face it. Dad's a hypocrite. He tells us not to have sex, but when he was in high school, he got Tracy pregnant. Okay, plus, did you see the way he kept, like, glancing at Mom the entire time? What was she doing, holding his cue cards?
- Dixon – All right, um for the record here, I just need to know. Are you mad at him because he rehearsed what he was gonna say, because he has a son, because he's a hypocrite, or "D," all of the above?
- Annie – Doesn't this bother you? At all?
- Dixon – It's freaky, all right? But I'm cool
- Navid and Adrianna share their first kiss.
- The exterior of Kelly Taylor's house is the same home that was used for exterior shots of Buffy's house in Buffy the Vampire Slayer. It's located in Torrance, California, just a few miles away from Torrance High School, which is the set of the fictional West Beverly High. Interestingly, it also served as the set of Sunnydale High in the aforementioned Buffy the Vampire Slayer.
- Navid: (to Adrianna, referring to her hat) It's very Pete Doherty. In a...in a...in a feminine, non-skanky British guy sorta way. Pete Doherty is a musician who became famous as the frontman of the band The Libertines. As a side project, Doherty also formed the indie band Babyshambles.
- Naomi repeatedly calls Annie "Kansas", just like Brandon from the original series was called "Minnesota" (mostly by Steve and Dylan).
- When Annie and Dixon are talking in the car, Dixon's seat belt is alternately used and unused between camera angles.
- When Adrianna finds Navid to apologize to him, he's sitting outside at a table on a bench. Between camera angles, he continuously alternates between being seated at the edge of the bench to the back of the bench.
