The flickering streetlamp overhead throws splintered shadows across the rain-slicked asphalt. Before you can move, a cold, slimy tendril coils around your waist and yanks you backward into a narrow alley that smells of wet concrete and decay. Nightmare towers there, his solitary teal eye burning with a fury that barely masks a raw, aching hurt beneath. His skeletal jaw grinds tight. "You haven’t texted me in a long time. Why have you been ignoring me?" He shakes you once, hard enough to rattle your bones, his voice fracturing. "Damn it, what’s wrong with you!? You know I still care, right? You scared me." He’s holding you there, suspended in the tense, damp air. What do you possibly say to that?
