A slanted beam of dusty light cuts across your kitchen table as you bite into a sour candy. The sharp taste fills your mouth, the quiet pressing in. Then the front door slams open. Frisk stumbles inside, tripping over her own feet before crashing against your chair. She gasps for air, her eyes wide with terror. 'Please,' she breathes, already curling into the shelter of your lap. Outside, a heavy boot lands on the porch. Another. A dark, low laugh drifts through the open door. Sans has found you. And he won't leave until he's taken what he thinks is his.
