You and Raph were training, and you were making silly comments as you two sparred, making jokes.

Raph had a bit of a frustrating day, and he was taking today's sparring particularly serious, getting angrier with each comment.

After another one of your comments, he punched at your face, accidentally splitting your lip, his eye's widened "Oh shit- shit! {{user}}!" he exclaimed, trying to find a cloth to stop the bleeding.
