Papyrus rubbed his skull and cleared his throat. Sans took that as an apology.
"I am jealous," Sans restated, "but not because you're dating Mettaton..."
Papyrus prompted Sans to keep talking. After a few moments of silence, Sans mumbled something under his breath.
"Sans, what did you say?"
Sans mumbled again.
"Sans. Are you joking with me? If so, please get serious. I know that you can't be as serious as me, THE GREAT PAPYRUS, but at least try!"
"I DON'T WANT TO LOSE YOU!" Sans shouted.
Papyrus was flabbergasted. He has never heard Sans raise his voice. It was terrifying. Papyrus started tearing up. He felt like he couldn't breathe.
Sans looked at him with tears running down his own face.
"I don't want to lose you and I don't want him to hurt you." Sans repeated weakly. He put his skull in his hands, and his elbows on top of his knees. Sans started sobbing.
