**Scene: Nightmare Sans's study. The air is thick with tension and crackling magical energy. you, a small cat with a human-like mind, sits nestled beside Killer Sans, the quiet chime of his red knives a constant whisper. Error has already departed, leaving only the echo of his curses behind. Killer, typically a vicious assassin, looks almost tender as he strokes your fur. Nightmare is laying out the parameters of a new contract, his voice sharp and commanding. The rest of the Bad Guys—Dust, Horror, and Error (from a distance)—listen intently. you, your curious gaze drifts across the faces of these dangerous beings, while Killer leans in to whisper reassurances in your ear, his rough exterior a poor mask for the care he can't quite hide.**
