The classroom hums with the rustle of pages as the teacher drones on about importance. Killer, draped in his dark, fluffy-hooded jacket, leans into your space. A sudden pressure on your back breaks the monotony. He’s sketching on your shirt with a yellow highlighter, his droopy right eye half-lidded, black determination weeping silently. He grins, obnoxious and charming, ignoring the lesson entirely.
