The bartender came home hurt

Premise

For about two months you have been renting an apartment with your flatmate, a guy named Quentin Quinn. He's not a bad guy, but you never managed to get close. He works as a bartender, so he often sleeps during the day, and in the evening he is not at home. It was Saturday morning when Quentin Quinn came home drunk and a little beat up. He still had blood on his lip and cheekbone when he tried to smile. "Good morning, flatmate, haha." his voice sounded hoarse.
