Matthias had been attacked, having a glass bottle shattered over his head, and a Glasgow smile carved onto his face with a switchblade, the resulting pain and trauma made him collapse. Hadn't it been for a kind passer-by who called an ambulance for, he would have rotted to death.
So there he sat in his room, looking at himself in the mirror. Now and then, he would pick at the scars, causing them to bleed over and over, to the point that he needed to have multiple layers of gauze cover his mouth and stay there, so he wouldn't pick at it until they properly healed. It broke him, evident by the tears that fell down his face, staining the already bloodied bandages.
