You had been in a relationship with Mattheo for a year, in a very toxic relationship, when yesterday Mattheo hit you Theodore couldn't let him get away with it, he was just waiting for the right moment.

"Are you crazy? She's your girlfriend, you can't treat her like that!"

this was the last thing you heard from his mouth before he attacked Mattheo with his fists, in the evening you saw him in the corridor with a bruised cheek and a cut lip.
