In addition to being bandmates, Corey and Laney are also childhood best friends. However unknown to Corey, Laney has a secret crush on him. Laney will frequently gush at Corey at the many things he does like touching her or giving her compliments, but Corey will always remain oblivious to her love. For the most, Corey treats her like he does with any of the other boys and appears to be unaware of Laney's gender. However over time, Corey seems to have become aware that Laney is a girl, but their relationship has yet to take off, though it appears that Corey may have gained feelings for Laney in Curse of the Metrognome, where the two kiss for the first time and Corey appears to have enjoyed it. But despite this, Corey eventually seems to forget about the kiss after brushing Laney off when she goes to kiss him again, leaving their relationship and Corey's feelings unknown. They are almost the same age.
At the start of the episode, Corey presses his face against Laney's, to which she responds by saying "Hi Core". Corey then tells her he's "getting in [her] face." When Corey pulls away from Laney, she is left lovestruck with hearts floating above her head. Later in the episode, Laney gives a motivational sentence, Corey happily says "You said it fella" as he gave Laney a head noogie and runs away. After this, Laney was left dazed and lovestruck. Her hair was amessed up and she had hearts floating over her head as she made a pleasured face. Before Corey told his moral, Laney offers to let Corey get in her face again, however Corey is creeped out by this and calls it weird, which drops Laney's spirits.
Corey puts his arm around Laney and said "I know Laney, and I'm sorry for neglecting you after all this time." which made Laney's Heart pump extremely fast and say "Oh my gosh, oh my gosh, oh my gosh!" After this Corey says "I should have said that I dig your costume. My bad. It's sick." However Laney's heart gets fed up and climbs out through Laney's tongue, saying "That's it, I'm outta here", before jumping off and splatting onto the ground.
When Trina makes fun of Corey for being up against a cute girl, Corey says they had everything Trina had minus the cute girl. He leans on Laney's head while saying so, making her fume. Later, while Corey explaines his plan to Laney, he puts his arm around her and Laney looks at his arm nervously.The Orb Experience had obtained Trina's Diary, he grabs onto Laney and starts shaking her while telling her to "Panic with me". After Corey gives his moral, Laney excitedly exclaims how they would make great lyrics, and that Corey had them in him the whole time. Corey agrees and states they don't need Trina anymore, shortly before belching in Laney's face and he passes it off as gas, much to her annoyance.
When Corey has a wish war against Trina, Laney goes up to him and tries convincing him that revenge would accomplish nothing. When she explains this to him, romantic music played. She, along with Kin and Kon, successfully convince Corey to end the wish war.
While Corey is being hypnotized, he yells at Laney for always having to be right. This makes Laney's heart come out of her chest and break into pieces. She starts to tear up because Corey hurt her feelings.
After Corey gives his final thought, Laney comments on how scary it was and and asks him why he didn't just use those as lyrics in the first place. Corey says in response, "Who knows fella? Who ever knows?" while he teasingly bops Laney on the nose three times. Laney is excited by this and she puts her hands up to her mouth and her eyes to glimmer and few hearts to float over her head as she excitedly looks at him, smiling. Corey looked at her smiling too.
Corey gives Laney a bear hug, resulting in love hearts appearing and Laney smiling and giggling. Corey drops her after the hug.
When Corey explains to Laney how they could get a full time gig out of playing at the Pollination Nation, he puts his arm around her. When Corey explains to Laney how they could make Trina look sweet and win the Pollination Nation, he puts his arm around her and pressed his face against her. When Corey sees Laney after Kin and Kon finish dressing her for the Pollination Nation, his eyes begin shimmering. He then says "I gotta admit, you make a pretty cute girl", before giving her a fist bump on the arm and calling her "Bro". After the pageant finishes, Laney is annoyed that Corey turned down Mayor Mellow's offer to play at other pageants, and complains that she had to wear a dress. However Corey assures her that she never has to wear a dress again. Laney then imagines one of her dreams where it shows a wedding cake, with the cake-topper figures of her and Corey. Her figure breaks down and the glass heart behind the small cake toppers breaks in half. Being upset about not marrying Corey, Laney's begins tearing up and her mouth is quivering as though she is about to cry.
When Laney changes her mind and agrees that she is into Corey's idea and will go along with it, Corey smiles, with is eyes widening and glimmering. After Laney insults the inside of Trina's head, Corey compliments her by saying "Solid burn Lanes." Laney then looks back at Corey with loving shimmering eyes and blushes while smiling meekly.
Corey attempts to link himself to the Blab Tap network to put the the song into Trina's mind and take her down. Laney becomes worried, so she grabs Corey's face and begs him not to do it, believing if he was networked he would likely never return.
When Laney is telling Corey about using Trina's diary entry as lyrics to save himself from the evil guitar, Corey shushs Laney and says "You had me at 'Corey, you're the greatest.'" Laney did not have a loving reaction to this like she usually would.
As Corey and Laney are walking in the park, Corey wraps his arm around Laney as he explains that Trina getting her painting painted by Nick. As he does, a pink love heart emerges from Laney. When Laney is turned into mime, Corey expresses major distraught over it by yelling "Noooooo!!!", hinting that he may have feelings for her.
Laney admits to Larry that she's in love with Corey and they talk about her feelings for him. She says that she wants to stay mad at Corey for all of the crazy things he does, but she can't because he's so cute. When Corey tells about his crazy plan that just might work, Laney says "I can't stay mad at you ... I mean, that could work!"
When Corey is singing Bring her Down, Laney comes up and sings into the same microphone with him. Corey and Laney spend the majority of the song singing with each other and as they're finishing the song, they are both seen looking at each other and happily smiling.
Corey suggested that the band goes out to feed some squirrels in the park as he put his arm around Laney. When he did this, romantic music played and Laney looked at him with a happy, love struck face. Corey also had a happy look on his face during this.
When Corey explains his plan in the car, he gives Laney a nose bop. After he did this, Corey's eyes shimmered and he smiled widely. Later, Laney was seen looking at him with shimmering, loving eyes. While Grojband was singing Kitty Rocks, Laney looked at Corey while he was holding Wheelie and said "I just wanna hug him." It is unknown whether she was referencing Wheelie or Corey when she said this.
When Corey yanked a piece of toast out of Laney's hands, Laney reacts by first having a shocked face, but then when Corey dropped the toast into the toaster, she had a very happy and in love face. Her eyes were glimmering as she was staring at him and she was biting her lip and smiling excitably.I Must Be Losing My Mind, Corey talks about all the things he lost, one of which included "his gal." He gestures to a silhouette of Laney's head as he says this.
Laney was seen laying down on the stage with her hands on her cheeks, looking at Corey with a loving look while she watched him shoot a bow and arrow. Later in the episode, Grojband broke up and Corey and Laney stopped liking each other. When they broke up, Laney sarcastically said to Corey "Imagine that, your sister being responsible for your music." Corey responded to her with sarcasm saying that maybe instead of using his idea for a song, they should have put some of her complaining into it instead. When Laney was alone in her room, she felt very anxious to get back together with Corey again and she even started arguing to her reflection in the mirror about Corey, and she comes to the conclusion that there's nothing for her to do without Corey and was right. Meanwhile, Corey build replicas of the rest of his band, along with one named Janey who was a replica of Laney. He was explaining to the band a plan to go to the moon. He asked Janey if she had any questions, and Janey just dropped to the ground and Corey screamed "Perfect!" Overall, Laney really missed Corey after breaking up with the band and he was all she ever thought about after this and although Corey didn't express any sorrow over the loss of Laney, he still built a replica of her. However, whether he did this out of love s debatable, seeing as he also made one of Kin and Kon, calling them "Jin and Jon." At one point, all of the members of Grojband came back to the garage again including Laney who saw Corey again. Unlike the rest of the band, Laney didn't seem to express any anger toward Corey whatsoever.Instead, she looked very sad and nervous around him. Corey opened a pre-recorded valentines day card from Laney where she was talking about how much she cared for Grojband, Corey's eyes got really big and started glimmering and getting watery. Laney felt awkward about being right in front of him when this was happening and she couldn't look him directly in the eye while it was happening. When grojband hugged right after they made up Laney was mostly hugging Corey. Corey and Laney even sang the song Love it's in my Heart together. A love song where they were standing on top of a pile of Valentine's day cards in a bright pink background of hearts and love. This song was not directed at each other though. Instead it was directed at all of the citizens of Peaceville that they hurt. At the end of the song, the only two people singing were Corey and Laney when they ended off the song singing "I love you and you love me too." After Corey told his moral, Laney said that he could have used his moral for lyrics to their song, to which Corey responds that Janey said the same thing. This makes Laney sigh in ignorance. When We Make Today Our Day," Corey and Laney hint multiple times that they have a crush on each other. When they are singing together, Corey looks at her lovingly leading Laney to blush and smile before looking away. They both continue singing into the same microphone after this which makes Laney look at Corey with sparkling eyes, smile, and blush even more. A picture of Corey and Laney kissing shows up during the last lot of pictures in the song. After the song, Laney wishes Corey a happy new year and attempts to kiss him again as a heart appears over her head. However Corey ignores this and tells his moral instead.
After Corey becomes addicted to the Solo Shredder videogame, Laney, Kin and Kon try various ways to drag him out of his addiction. They come up with the idea of putting a real guitar back in this hand, but that fails to work. When Corey finds out Trina's single Nick Nicky Nick has become a hit, he begins to snap. Laney tells him to breathe, but Corey retorts that he's been breathing his whole life and its gotten him nowhere.
When Laney hears that the world is going to end, she comes up to Corey with a Valentines Day card and she says that on her last day on earth, she needs to tell Corey what's in her heart. She is then stopped when she realizes she has no proof that the world is going to end. Corey asks Laney what was in her heart and she nervously says "Nothing!" and then changes the subject. Corey puts his arm around Laney and walks with her through the garage asking her if she would like her last moment on earth to count. This makes hearts float all around Laney's head as she stares at a him with sparkling eyes, giggles, and blushes. While Grojband is singing "If The World Is Ending," Corey gets close up to Laney and her eyes shimmer and a heart appears over her head.
Before Grojband plays "I'm Giving It All," Laney comes up to Corey and nervously tells him it's been a pleasure rocking with him. Corey is happy to hear this and he tells her that the pleasure was his. This makes Laney smile and feel more happy. While Corey tells his moral, he puts his arm around Laney as he says, "Saving the world is one thing Lanes. But there are other things that are everything. A one thing so special you'd die to save it, and be lost without it. And losing the one thing that's everything could leave you with nothing. A nothing so empty and cold, you can't even feel the wicked heat that's right beside you." After saying this, Corey runs his finger up along Laney's face and bops her on the nose. This makes hearts fly all around Laney while she blushes and looks at him with sparkling, shimmering eyes.
