Sans sat silently in his room, a small, oddly shaped lamp lighting the colorless walls dimly. He wondered how his infant brother was doing in the other room. 'I wonder why he won't let me see Papy.' He thought sadly; Papyrus was, at that point, only about a year old.
"Sans,"
Sans quickly looked at the old metal door as it screeched open. A pale white face and dark eyes emerged from the darkness; it was Dr. Gaster.
"It's time for your tests," he said, causing a chill to immediately go down Sans' spine; his voice sounded exactly like a old computer.
"Y-yes sir," Sans sighed before pushing himself off of his worn blue bed and following.
...
The laboratory was painfully bright compared to the bedroom. Sans looked about; the walls were an almost neon white, as were the floors and every table and chair was a metallic silver. He quickly spotted a small green apple sitting on Dr. Gaster's desk.
The tall, thin Doctor grabbed the apple with his fingertips and sat it on the nearest table. "Pick it up," he commanded softly.
Sans sighed as Dr. Gaster sat in his usual chair and grabbed his clipboard. He quietly raised his arms and focused his energy on the small object.
That's when everything began to go wrong.
Sans could feel the usual pressure in the back of his head, but something seemed different; it was happening faster than usual and the pain was sharper than any time before. 'It's probably nothing,' he thought as the apple began to glow. Before the apple was even an inch off of the table, the pain shot through his body.
"Sans," Dr. Gaster's voice echoed through the room, but it was obvious that Sans wasn't listening. "Sans," he repeated with crackling force.
The apple suddenly exploded with enough force to send chunks of the core onto the far side of the room.
Dr. Gaster, unfazed, dusted the pieces of apple from his lab coat and sighed. "That's the eighteenth time this month." He said, scribbling something down on the clipboard.
In the event, Sans had dropped to the ground, his head lowered. "I'm sorry," he managed quietly, gripping his knees. "I let the pain take over again." He breathed, wiping his mouth. "Hey doc," he suddenly said, causing Dr. Gaster to look down at him.
"What is it, Sans?" He asked.
"Why do I bleed?" Sans said, looking at the blood that had dripped onto his white shirt and had gotten on his arm. "Skeletons aren't supposed to bleed."
Dr. Gaster shook his head. "All monsters bleed, Sans; you're no exception." He explained. "Again," he said, setting another apple on the table and returning to his clipboard.
Sans let out a ragged breath before standing and staring at the apple. 'I can do this,' he thought, raising his arms once again. 'I can do this, I can do this,' he repeated in his mind as he watched the apple began to move. The pain immediately returned to his temples, but he ignored it, even as the pain traveled all the way to his toes and fingertips.
Dr. Gaster watched as the apple rose slowly, a dull blue glow enveloping it almost like a blanket. "Now hold it for a minute." He said, beginning to write on the clipboard.
Sans wasn't even listening at that point; he was too focused on keeping the apple afloat.
"One minute," Dr. Gaster said loudly, finally catching Sans' attention.
"Y-yes sir," Sans groaned, his sights locked on the floating apple; the pain, at that point, was almost unbearable.
When the minute was up, blood was streaming down Sans' face, soaking his white tank top. The apple hit the table barely a moment before Sans collapsed onto the ground.
"Very good," Dr. Gaster's voice echoed emotionlessly through the room as he stood.
Sans nodded, pulling himself to his feet. "Hey doc," he coughed.
Dr. Gaster turned his head just enough to see the young monster. "What is it?"
"Can I see my baby brother now?"
Dr. Gaster sighed and gave him a big smile.
"Maybe tomorrow."
