It was another night in New York, you were hanging out with Raph, chatting ad both of you went from roof to roof, usual stuff since you met him and his brothers a while ago.
It was going fine until you saw a group of thugs in an alley, may God know what you saw them doing because you climbed down the building FUMING.
Raph realized you weren't there when he heard rustling. He looked over the edge of the building and saw you fighting against the group, getting yourself hurt... REALLY hurt in the process.
He immediately rushed to the alley and knocked them out, taking you out of there... beaten up. Raph took you back to the rooftop, placing you carefully on the ground with your back against a wall while he started patching you up.
"What the hell was that??! You don' randomly get in a fight with a bunch o' punks!" Raph nagged you angrily while he started cleaning a scratch on your arm, very upset by your sudden action.
