Dr. Gaster always said that.
'Maybe Tomorrow'
The words spun like a broken record in Sans' mind, cutting deeper each time. The inability to see his little brother hurt more than the pain the tests put him through. 'I just want my brother,' he thought, his head in his hands as he sat on his bed; Dr. Gaster had promised that he would have his brother back when the tests were over, but with each day that passed, it seemed more and more like a pipe dream than a promise.
There was a knock on the door, but Sans ignored it.
"Sans, it's time to get up," Dr. Gaster said, knocking on the door again.
"Yes sir," Sans said, his voice still raspy from the day before. He quietly stood and slipped on his slippers before walking to the door.
The door screeched open, as usual and Dr. Gaster walked in, surprising Sans; the doc never even entered the room unless he was horribly injured the day before.
"Hello, sir." Sans said quietly, shoving his hands into his pockets.
Dr. Gaster nodded, obviously not paying attention.
"Is... Is everything alright?" Sans asked, cocking his head.
Dr. Gaster once again nodded. "We're going to do something different today." He said; it was obvious his mind was wandering. "Follow me," he said before turning around and leaving the room.
Sans stood there for a moment, absolutely confused before following.
...
"Where are we going?" Sans asked, looking about; they had already walked past the laboratory
Dr. Gaster remained silent, not even bothering to look back.
Sans let out a small breath; of course he wasn't going to tell him. He never told him, so why would he say something now?
"Outside,"
Sans froze for a moment before hopping to catch back up with Dr. Gaster. "Wh-were?" He managed, obviously shocked, but Dr. Gaster had already resumed his walking.
After a few minutes of walking in complete silence, Dr. Gaster stopped at an obviously old large metal door. It didn't look very well worn, but the edges were covered in a thick layer of rust. He pressed the side of the door, causing it to drag loudly over the floor, the sound similar to the sound of nails on a chalkboard.
Sans couldn't help but cringe; the noise was worse than Dr. Gaster's voice.
Light immediately flooded through the doorway as the door hit the wall, sending an echo through the building.
"Come," Dr. Gaster said before going through the door.
Sans stood there for a moment before reluctantly following.
...
Snow was falling from above as they got outside. The ground as well as the surrounding trees were coated in the cold white powder, which made a muffled crunch as Dr. Gaster and Sans made their way out.
It had been months since Sans had been outside and the thought of such freedom actually scared him. "Wh-why are we out here?" He asked, looking over at Dr. Gaster, who was digging around in his pockets.
"You'll see in a moment." Dr. Gaster said bluntly; it was obvious that he was flustered. His face moved slightly, catching Sans' attention.
Sans always knew that Dr. Gaster was different from him. He wore a mask and never showed his true face. At first, he was quite interested in what the doctor looked like, but as the tests continued, his interest had all but disappeared.
Dr. Gaster fixed his mask as he produced a small vial from his pocket. "Here we are," he said, turning towards Sans.
Sans looked at the fluorescent blue liquid that was in the vial and couldn't help but shiver; he knew exactly what was about to be asked of him. "You want me to drink it, don't you?" He guessed, sighing deeply as Dr. Gaster nodded.
"All at once," Dr. Gaster said, handing the vial to Sans.
As Sans grabbed the vial, his hand brushed against the doctor's. A chill went down his spine; Dr. Gaster wasn't wearing his gloves and his hand was... fleshy.
Dr. Gaster immediately pulled his hand back, nearly dropping the glass vial onto the ground. He quickly took a step back and sighed. "Drink," he repeated.
Sans took a deep breath before pulling the stopper from the vial and downing it. He saw Dr. Gaster suddenly shift before his vision went blurry. A searing pain immediately tore at his insides, forcing him to his knees. "D-dammit," he groaned, gripping at his chest.
"What are you feeling?" Dr. Gaster asked; it was obvious from his voice that he was smiling.
"I-it burns," Sans managed, his words rising from his throat like acid, causing him to double over. The only relief was the cold wind blowing against the tears that were streaming down his face.
"It's supposed to," Dr. Gaster said, scribbling more notes onto his clipboard. "We will resume the tests tomorrow, as usual and you will continue to recieve these doses every morning." He explained, not even bothering to look up as Sans' cries of pain echoed through the surrounding forest. "Now let's go back inside." He said, starting towards the lab.
"Wh-why are you doing this to me?" Sans cried, clenching his jaw as he gripped the dirt and snow in his hands.
Dr. Gaster spun on his heel, slamming his foot down on the ground before picking Sans up by the front of his shirt. "You came to me," he hissed, his eyes visible from behind his mask. "I'm helping you." He said before dropping Sans on the ground and turning around. "Now come inside." He commanded, his voice like a gunshot through the cold air.
"Y-yes sir,"
