Okay, so this might sound crazy, but I've been wondering, are the CMC's cutie marks friendship?
Think about it. I would make sense that Hasbro would want to throw a little curveball and have the cutie marks be friendship. I mean, the cutie marks we suspect are way to obvious, (scooter, microphone, some sort of apple.) and it would also make sense because the CMC have been through lots of stuff together, and it seems as if you cannot separate them. Anyway, just a theory, and I'd love to hear your inputs.
