NOTE: There is no ship here. I have nothing against Tom Dupain. I just randomly thought about this and couldn't get it out of my head. Now it's a fic. I blame my husband. Been binge-ing the show. Also, this was not what I had planned for the next post. 



Marinette was having a boring day. Paris was fine which was actually good. She was going to be able to go to the fabric store after school. No akumas and she actually studied for her language test.

Nothing could go wrong.


Suddenly, the window crashed open into the class and a man was sprawled out in front of her teacher's desk.

Marinette stood up and was ready to get the nurse when she saw exactly who was on the floor.

"Dad!" she cried, running out of her seat.

Marinette kneeled down next to him.

"Do you need your eyes checked?" asked Kim, "That's not Mr. Dupain."

"This is my dad; my biological father!" she shouted.

The room went quiet.


"What the fuck, Dad?" Marinette yelled, "What did you do this time?"

"Hey, Starling. Blame your grandmother for sending me on a wild goose chase. Speaking of goose, got any Grey?" he asked.

It was hard not to notice the similarities once he sat up. They had the same blueish-black hair and bright blue eyes.

"I'm not twenty-one yet and with the way you and grandma down a bottle, I don't think I want to." Marinette answered, "You're all cut up and bruised."

He quickly pulled out a gun from his suit pocket and faced the window.

"Is it Barry or Katia?" she asked.

"Nope." he answered.

"Good." Marinette said, forcing him down on the ground, taking the gun and shooting the intruders with zero hesitation.


"Mahp. Mahp. Mahp." he said, poking a finger in his ear, "Dammit, Marinette; my tinnitus!"

"That's what you get for firing these without earplugs!" she shouted, turning to look at him, smacking his lips still, "You good now?"

"Yeah." he answered, smiling at her.

"How's your tinnitus?" Marinette asked.

"Better most days. The ringing never ends. Is someone's phone going off?" he questioned.

Marinette sighed and put the safety back on the gun, handing it back over to her father.

"No, Dad. No one's phone is going off. Where are you not injured? Any bullet holes?" she asked, heading to her seat and packing her bag.

"No holes." he said, standing up, proudly showing off he was bullet free.

"Good." Marinette smiled, before pulling his arm into a fireman hold, "Let's go. I'm taking you to Maman where we can patch you up and get you a new suit. You look like shit."

"Woodhouse-" he tried to fire back.

"Is still in Venice with the Pope?" she questioned.

"Yeah." he grumbled, as they exited the room.


The room sat in silence trying to comprehend what happened.

Since when was Tom Dupain not Marinette's father? Who was that guy? Why was he being chased and since when did Marinette know how to fire a gun?
