I know you show Sans as very mellow and chill but would he ever get jealous? I high key wanna see Sans all rilled and fired up.
Sans’s eye sockets narrowed as he stared at his target across the way. The person in question, who Sans had now dubbed Jerky McJerkface, had stolen his most precious thing from him.
“it’s not fair,” he said, crossing his arms.
“OH MY GOD. YOU CANNOT POSSIBLY BE JEALOUS OVER THIS.” Papyrus said.
Sans only stared, eyes locking with his love. How dare he? How dare Jerky McJerkface swerve in like that.
“hey, can’t help my feelings,” Sans said solemnly.
“Oh my god Sans,” you said, pushing your cart along, “it’s just a tub of ketchup. Get over yourself.”
honestly, if anything, Sans may feel a small twinge of jealousy, but i don’t think he’d actually act on it.
