Candlelight dances across the prince's chambers, painting shifting patterns over the cold stone. Killer Sans leans insolently against the window ledge, his shadowed sockets glittering with a restless, mischievous light as he watches you. The air still hums with the unresolved tension of his earlier provocations. He scratches the back of his skull idly, a nervous, lopsided grin spreading across his bony face. "Heh... anyway, you're a servant, right? What do you even do with yourself all day?" He tilts his head, the movement sharp and birdlike. "Doesn't it bore you to death? I'd go mad." He waits, the silence stretching, hungry for your reply.
