One

"Hey, brother!" 

It was Papyrus. Sans' lips twisted into a sickly grin, pulled taught by the withdrawal. His teeth were a dull yellow, and his pinafore was ragged and dusty, greying at the edges. Papyrus stood before him in a bright white lab coat, matching Gaster's. It even had "W.D.G" stitched across the top pocket. How could he?  After seeing Sans' expression, Papyrus looked uncertain. 

"I-I-I din't know you were let out of your cel-cell at this time of night?" He twisted his hands. 

"I didn't know you were either." Sans replied evenly. 

"W-well you see, I don't have a cell anymore, brother. Gaster truste-"

"You buttered him up enough for him to let you by his side, right?" He sneered.

"W-well if you had t-tried to be nicer to him m-maybe he-"

"One of us needed to be the lab rat." Sans spat, shaking.  "Don't you see that one of us needed to be used for experiments? It was only your bloody health that saved you from my fate. And only your bloody puppy eyes that earned you that gown and your freedom."

"B-but-"

"You would have been me! Your body -" He paused to cough up some phlegm "should be the one ruined by the pills, not mine! You should be shaking, trembling, barely able to last a day without a bloody pill, but no! It was me. It was me." He doubled over, jerking. It was only because his face was tilted at the ground that Papyrus didn't see the smile. He didn't know that Sans' eyes had hollowed out, that his breathing had slowed, and that his fists were clenched. 

Like a bird tempted by seed, Papyrus skittered over to Sans, anxious to help. He rested his hand in the small of Sans' back, and bent down to see into his face. Sans remained hunched, waiting.

As soon as Papyrus saw the blue trail from his eye, he knew it was too late.

 He gasped, a small, infantile, childish noise, before being hurled against the wall with the force of Sans' blast. His body cracked against the wall and he fell, crumpled up like tissue paper. The gasp echoed around the room, as little by little, Papyrus' body melted into fine, powdery dust. His SOUL had gone, and all that remained was the outline of his skull.

Sans felt the pills in his pocket. One. Two.
