Octavia was always one for competition. Unless, that is, the competition is forced upon her by the mare of her nightmares. And it's not that she's ever had a problem with Canterlot nightlife; she just has a problem with ponies named Vinyl Scratch. Not that anypony knows why, though, and Octavia isn't about to share embarrassing secrets.
