"In fairness, the openers are not in-universe cannon (discord is shown living in Flutter's home, despite three's a crowd implying he lives somewhere else) and the mirror universe converts dragons into dogs and dogs into humans, turning alter egos into serperate enities (like the shadow bolts, an alternate form of nightmare moon) does not seem far off in my opinion, i would like to see a main series where they are both in the same shot in the same scene and is clearly seperate characters in-universe."

based on a personal headcannon of mine, with the above comment being a argument of why it's still the case and possibly canon. My oc, Artsy Canvas will serve as the narrator, as he did for my early proto-fics

Disclaimer: (insert standard licensing disclaimer here)…and Constructive criticism is the best criticism, all other criticisms are, above all, pointless of fixing the issues and thus will be considered useless and will be deleted, the only reason i bothered writing this is that they are not any other fanfics where Photo Finish is a stage name for Rainbow Dash, but recommendations with this headcanon as a plot element are welcome, as long as you put the link in the comment.

Will be rewriting this as a separate fic.
