There, they found the "mystery" wasn't about malice, but stage fright. They discovered Kevin and Leo hidden away; Kevin had "borrowed" the diary to add a secret rap verse he was too nervous to show Barbie, and the guitar had been moved by the stage crew (wearing blue paint) for a surprise tuning service. However, the neon green pick belonged to Raquelle, who had tried to hide the diary to stall the show, only for Kevin to accidentally "save" it first.
Using Tia’s tech skills, they tracked a faint GPS signal from Barbie’s "lucky" keychain attached to the guitar case. The signal led them not to Raquelle’s house, but back to the school basement.
The halls of Golden High were buzzing. The annual "Spring Jam" was only two days away, and Barbie’s band, , was set to headline. Everything was perfect until the morning Barbie opened her locker to find her lucky diary missing—and her signature electric guitar gone with it.
