Scootaloo somehow managed to get an interview with the Ponyville most well known musicians for the Cutie Mark Crusaders. The musicians were Octavia and Vinyl Scratch, during the interview Octavia was skeptical about of her best friend, she didn't have much to say and she was acting odd around them, and then she realized that she doesn't know much about her herself.

Finding out Vinyl's Jarring, embarrassing and interesting secret in the process, along with a filly named Sweetie Belle.
