So Luniverse AJ stays in Manehatten and gets into the Jazz scene. She plays the trumpet at a nightclub
Jackie [as she's more commonly called] is a lot less traditional then her canon counterpart and seems generally more relaxed.
She's still a very honest little Earth pony but is no longer a farmer or even a family mare.
While she visits Ponyville fairly often she's never there longer than a week or so. She is in constant contact with her family though and when Jackie is playing in a more open environment all three farmers come to watch her

Jackie lives in an apartment with Vinyl Scratch, Octavia and their little cocker spaniel Banksy!~
