Taming the Demon
Marinette and her new gang go on a trip to Gotham for a break from Lila crap. They meet a certain family there, the Waynes. Later, they go back with their class, Lila lies (No surprise there) and she gets busted by the Waynes and Marinette's gang. Disclaimer: I do not own Miraculous Ladybug/DC or any of the characters...
