No lie, I've been slowly writing a fanfic about this very idea since the end of season 2. It's going to be about a pony named Jack and his adventures that coincide with the Mane 6. Pretty much, it would play out like Cutie Mark Chronicles, where he had a connection to the Mane 6, but through both (maybe all three, considering how long it's taking me) seasons. For instance, he would be in Manehatten during the summer sun celebration (equivalent to times square during new years) when NMM escapes, or in Fillydelphia during the parasprite invasion. All and all, a really big, all encompassing adventure.
