The Gravity Falls we all love, spiced with some miraculous mess. (Formerly named as "Pilot"). It's the same story plot through out the entire series, but with the miraculous charms and Kwamis. Plus maybe a little of Dipper and Pacifica romance along the way.
Dipper and Pacifica were astonish that their other selves are superheroes.
Soos "Dudes that awesome!"
Wendy "Really cool!"
Mabel "How come Dipper and Pacifica are superheroes and not me?"
Shinshinjane "Either no one likes you, or you haven't been worthy to have a miraculous or a Kwami."
