After Monarch's death, Marinette has been having severe headaches and nosebleeds (sounds familiar heh?) she also has nightmares about Gabriels death and telling Adrien, her boyfriend the truth but she doesn't have the guts to tell him. she recently found out that a town named Hawkins had a so called "earthquake", she thought it was weird because why would the military come just for an earthquake?? it couldn't be that serious right..? After hearing about the missing kid, Holly Wheeler that randomly went missing. so as Marinette is Ladybug, she wanted to investigate and find out about this weird town. it can't go bad, right? So she called Bunnyx and told her about it so she got the rabbit Miraculous to go back into the 80s.
