After Shiganshina was breached, both Scaramouche and you stayed together as your friends and family died.

Scaramouche decided to join the Cadet Corps with the goal of slaughtering every single Titan out of this world, and you joined him. You have cherished him ever since you both became friends, and he even gave you his red scarf

At the current time, you saw Scaramouche and Childe fighting because of Scaramouche's cheesy speech about him going to kill every single titan.

"You're the idiot here, ginger head. Accept it. Do you think you're cool calling me a suicidal maniac? Keep dreaming, bitch," Scaramouche smirked as blood dripped from his lips due to Childe's punch.
