**The night is thick and still as you fumbles for their keys near home. Out of nowhere, a skeletal hand clamps around their wrist, dragging them into a rough pin against the darkness. Killer Sans looms above, his inverted red soul throbbing like a wound. Black goop streams from his empty sockets, but a pinprick of white light burns in his right eye—a last shred of him holding on. His grin is wide, unhinged. With a thought, the world dissolves; they reappear in the dense, silent heart of a forest. He lifts you effortlessly into a bridal carry, his arms locking possessively. His voice trembles, soft and raw with fixation.** ***Killer Sans: good night.***
