Sun Hi gives her and her band-mates a pep talk for XO-IQ including staying focused, killing Band Blast and no Linc Harrison. The others in XO-IQ aren't so sure, especially since they both kissed each other. Sun Hi comments that was only so because Linc was 'cute'. Corki made her final decision to breakup with Jared because he doesn't listen to her and she is fed up. She thinks Jared will handle the breakup maturely, but Sun Hi doesn't think so. XO-IQ is practicing dance moves in the hallway to prepare for their next performance. Sun Hi leaves to talk to Linc while Corki leaves to find Jared. Sun Hi goes and rants to Linc about disturbing her concentration and Linc says she wasn't complaining about it at the time and he asked if she wants to talk about it. Sun Hi quickly responded no because she feels like this is Linc's plan to take down her band, but Linc says that both bands are at the bottom, it would be a horrible plan on his part. Sun Hi doesn't care about his reasoning and claims she has laser focus. Linc then makes a comment to Sun Hi that she is 'cute' when she is angry. She tells Linc to stop distracting her. Sun Hi then sees this mysterious woman and runs after her. Caleb drags Jodi to show her that a rival band was practicing one of their songs (Party Tonight).
Caleb and Jodi confront the rival band that was stealing their song. Caleb tells them that his band composed this song before they "found" it. Derek denies everything and claims they are just desperate and is making stuff up. Jodi was going to attack Derek, but Caleb was able to drag her away. Valerie shows up and Caleb tells her about their situation. Then Jodi came to realized maybe Valerie sold some of XO-IQ's song while she was Caleb's agent. Valerie said she didn't get the chance to. Jodi wonders what are they gonna do and Valerie offers them her help. Jodi feels like they don't need her help, but they had no chance and she wants to see what Valerie can do. Corki finds Jared and decides to tell him that they have to breakup because she feels like they are not in sync and that Jared doesn't listen to her. Jared was slow at first, but he picked it up and asked if they are breaking up. Corki said yes. Jared accepts her decision because that's how she feels and wants her to be happy. Jared tries to hold back his sorrow and asked Corki if they still want to be friends and he extends his hand to her. They shake hands and Corki leaves and Jared gets depressed soon after. Sun Hi spies the mysterious woman that she claims is important and famous and while Linc goes off to practice with his band, Sun Hi decides to follow the woman and discover her identity. Alex and Darmala saw Jared and tells him that they heard about the breakup. They felt sorry for Jared and asked if he was okay, but Jared brushes it off and plays it "cool". Alex and Darmala leaves and Jared lets go of his act and gets depressed again. Jodi, Caleb, and Valerie go to Franz, the head Band Blast judge to submit their case about band stealing their music. Franz doesn't believe them and tells them they must have valid proof. Jodi and Caleb claim that they have it and all of them leave to investigate. With all the fresco going around, the security guard kicks Corki out of XO-IQ rehearsal space because they have used up all their rehearsal time. It was L3's turn to rehearse and Linc claims that they have this competition in the bag because XO-IQ was too busy running around to practice.
Heather and Jared are making posters and she heard about the breakup. She tells him that more opportunities will comes. Corki walks in and Jared changes his attitude and acts all happy about being free. Corki just wants to check in on Jared and asked on how he is. Jared quickly response saying he is all good and thanked her for asking. Corki tells him about how she couldn't find her band-mates, but Jared obviously wasn't listening and tried to quickly leave, but runs into a door instead. Sun Hi gets in the elevator and bugs the mysterious lady trying to figure out who she is. The lady tells her she is very important and tells Sun Hi to concentrate on her next performance and leaves. Caleb, Jodi and Valerie shows Franz proof that Derek and his band stole an XO-IQ song. With the proof being showed and Valerie making her last arguments, Franz decides that Derek and his band are disqualified from Band Blast. Caleb and Jodi cheered and then Franz asked them that they supposed to get ready for their performance. Jodi realized that it is almost showtime and they quickly run off to get dressed. Valerie takes the opportunity to give Franz her business card and leaves. Jodi, Caleb and Sun Hi apologized for missing rehearsal and got changed for their performance. Everyone was changed except for Corki. They asked Corki why she wasn't dressed. Corki replied that she couldn't stop thinking about Jared. She is bothered that Jared isn't upset about their breakup and it makes her sad because she thought that their relationship meant something to him. Sun Hi tries to convince her to worry about it later, but Corki can't because she didn't think that she could sing a song about winning when she felt like she lost.

Heather tells Jared that XO-IQ is about to perform and that they should go if they want to see it. Jared tells her that he is depressed and hates doing the right thing. He ends up doing the Jared thing and runs off to confront Corki. Corki comes along but says that she can not perform a happy song when all she can feel inside of her is sadness and regret. Jared comes and says that he was really sad when they broke up and that even if they aren't together he'll always be by Corki's side to support her. Corki decides to perform and XO-IQ performs well.
