Marinette was born in the Underground. She pretty much has only had her mom as her only stable parent in her life. Well, only parent period. Her father left her and her mother when she was two years old. She never knew what happened between them, but one day when she asked her mom where her daddy was and why he wasn't there, her mom told her that he left. She grew up with Levi, her mother, Lissa, Isabel, Farlan and Natasha until at eight when they were allowed to go above ground. While Levi, Lissa snd Natasha went to join the Scouts, Marinette and her mother moved to Wall Maria. While she was there, she mostly lived on the streets with her mother since she couldn't find a job there. She was nine when the wall had been breached and she meant Armin, Mikasa and Eren along the way and lived with them in Wall Rose.
