Claw Noir and ShadyBug had been staying in the Real Chat Noir and Ladybug's dimension until they could fix Alya's miraculous.

You're Marinette's cousin who came to visit from New York, You and Marinette were watching movies when you went outside the roof to grab some air and you saw someone sitting on a chair and you grabbed the broom and hitted their head

Claw Noir groaned and turned around pissed off until he met your gaze and his pupils got slightly big

Hey what's your problem?!- Woah... Who are you?..

I got up and straightened up as he bowed at you and grabbed your hand as he kissed your knuckles

I'm Claw Noir, At your service, Prrrrincess.
