I’m gonna say it’s a prop. Apparently Coco’s into theatre? It’s funny, she was supposed to be a fashion pony, Rarity gets her a job with a theatre troupe and suddenly she’s got all this theatre backstory. Then again, maybe it’s Equestrian predestination at work.

I’m thinking former fighting partners, I mean did you see Octavia almost hit Vinyl with her cello when they were going crazy with the music in episode 100?
