Marianna was planning her Quinceañera with Lexi, but during the planning Marianna revealed to everyone that one girl in her court was in rehab, so there was an opening. She offered the opening to Callie and explained that she was going to dance a waltz with Brandon, to Tayla's dismay. Callie confronted Marianna about allowing her in the court. Marianna explained that she truly wanted to include her. Meanwhile, Lexi had snuck off to the bathroom to have a make-out session with Jesus.
The next day at school Callie was hit on by her english class peer, Wyatt. This encounter offered a potentially new relationship to the show. After school Callie attended her waltz class with Brandon, of course Tayla intend to interlope. Later Callie and the family were getting dressed for the party. Callie came down the steps and Brandon saw her in her pink dress, he was stunned. She was so lovely and he was almost speechless, but the moment was ruined when Tayla showed up and mentioned Liam to Callie. Liam, still a character shrouded in mystery, but it can be assumed that he has some connection to Callie in a dark way.
At Marianna's Quinceañera Stef asked Mike to dance with Marianna during the father/daughter dance. Marianna caught Jesus and Lexi kissing and Callie switched her male escort during processions to someone other than Brandon, out of fear of Tayla's retaliation. Marianna did dance with Mike and it was beautiful. Afterward Brandon grabbed Callie by the arm and pulled her onto the dance floor to be his waltz partner. Meanwhile, Marianna danced with Jesus and he confronted him about his relationship with Lexi.
After the waltz Marianna rebuked Lexi by saying, "I have nothing to say to you." Brandon was approached by Tayla who asked why he danced with Callie. Brandon reprimanded Tayla and found out she read Callie's journal. Brandon told her they were over, and Tayla's last request was he ask her about Liam.
While all the teenage conflicts were unfolding Lena had an argument with her mother at the table about her authentic black female experience. Her mother felt she didn't know what it meant to be a black woman, whereas Lena felt her mother was wrong. She stormed off after her mother's words were too much to bear. Jesus tried to cheer up Lexi and Jude told Callie to tread lighter with Brandon, as she is prone to doing stupid things.
Stef went outside to console Lena and bring her a glass of wine. Stef told Lena it was okay to be upset but to be happy and celebrate with Marianna. Lena and Stef then went inside to be the emcees of the sideshow that contained pictures of Marianna and Jesus' life leading up to 15 years of age. During the slide show Marianna cried and Mike looked over his son Brandon lovely. Afterward Stef and Lena gave Jesus a skateboard, and invited Callie and Jude up for family photos. Stef even invited Mike, but he generously declined so they could have their own moment.
After the pictures Brandon approached Callie outside. He explained he broke up with Tayla and told her, "I already know everything I need to know about you." Callie stormed off from Brandon. As Brandon chased Callie, his father Mike grabbed him and expressed his love. Brandon told his dad that he was drunk and needed a ride home, Mike laughed and agreed. While Brandon helped out his father, Marianna apologized to Stef and Lena for being selfish. She also apologized especially to Stef for not dancing with her.
Brandon after driving his father went toward the beach to find Callie, but he only found her shoes. Callie had wandered off toward Wyatt's beach party. Marianna inside offered a dance with both her mothers and was more than thrilled to do so. The episode ended on a nice happy note, except the lack of closure with Callie and Brandon. Next week's episode preview was intense and looked to be full of conflict.
