Dark, darker, yet darker...
Darkest.
It was the darkest darkness Wingdings Gaster had ever know.
He floated in it, cold and alone. Like how he'd been just after the war but this time there was no warm light of a teenage fire elemental, there wasn't the comfort of the King and Queen.
He really was alone. He'd lost everything.
He'd been so happy with his sons, why hadn't he just accepted the miracles? Why did he have to want more?
All it was, was dark and quiet.
How long had it been...? A hundred years? A million years? No, it had only been a second? A week? He didn't know.
He wanted his boys.
He was floating in nothingness. He was everywhere and nowhere. He was a million pieces, yet he was whole.
The emptiness was driving him mad.
Black, dark, white, black, dark, white, black... Cold.
Yet even though all it was, was darkness, he saw everything. He saw Asgore find his children. He saw his old family die. He saw Sans trying so hard to take care of Papyrus. He saw his sons as adults; Sans a sentry, Papyrus a Royal Guard in training. He saw himself surrounded by his niblings as he read to them. He saw Papyrus's first day of school, he saw himself as a child running around with his siblings, he saw Sans's twenty first birthday where he got shit-faced at Grillby's, he saw sixteen year old Sans working three jobs to keep Papyrus living happily. He saw his sons' births. He saw himself at school as bullies surrounded him and began calling him names. He saw the battlefield, he saw himself waking up in the makeshift hospital after the war. He saw his sons living happily, he saw them living in misery.
He saw his boys' whole lives, he saw his own past but it was out of order and hard to keep track of, so confusing, Gaster gave up trying to make sense of it all.
Things began repeating, he kept seeing the same things over and over again.
He saw a golden flower. He saw that flower kill but who he killed Gaster couldn't tell; it was surrounded in darkness. He saw the flower make friends, he saw it kill... There was something about it that reminded him of Prince Asriel but Asriel was not a killer, it was weird. He didn't like it. He wanted it to stop doing whatever it was it was doing. He wanted it to stop resetting the world. He wanted it all to stop, he wanted to stop seeing the same things over and over, he wanted to die. He couldn't.
The void weakened ever so slightly...
"After all, it's rude to talk about someone who's listening."
Gaster flinched at the sound; that was one of his Followers, one who fell with him...
If they were here they could help each other, they could escape, right? He needed to find them.
He wanted to go to the source of the sound but it was impossible, the laws of physics didn't apply here. There were others trapped with him but they'd never see each other.
He saw the human.
They stopped the flower. They freed everyone.
Gaster felt so relived, his sons got to the surface. They got to see it, they were all free and there was peace between monsters and humans. Gaster felt all his regrets lift away, his sons could be happy, everything was okay and if they were happy, he was happy, it didn't matter if he was trapped in here, his sons were happy.
The human reset...
"W-WELL, THAT'S NOT WHAT I EXPECTED... BUT... ST... STILL! I BELIEVE IN YOU! YOU CAN DO A LITTLE BETTER! EVEN IF YOU DON'T THINK SO! I... I PROMISE... "
The human killed Papyrus...
Gaster screamed, he let out attacks at nothing, he could not kill the human for what they had done, he couldn't make them pay but he wanted to, oh how he wanted to. He wanted them to suffer for killing his child. He could not for he was trapped.
He mourned, he was in so much pain, he lost everything, his child couldn't die... Not sweat little Papyrus... He'd never hurt anyone in his life, he didn't deserve it. He could not believe what was happening, all was lost. He'd failed as a scientist, that was painful but not as painful as how he'd failed as a father. It was his fault his sweat Papyrus died, he should have protected him.
Gaster's rage and pain was uncontrollable, he felt it would've consumed his soul if he still had one that was whole. He wanted out, he'd make that human pay. They killed his child, he'd lost more, he was even more alone.
"... ... ... so... guess that's it, huh? ... just... don't say i didn't warn you. welp. i'm going to grillby's. papyrus, do you want anything?"
Gaster cried out, this couldn't be happening, it couldn't, not his babies, not his boys. This was exactly what he wanted to stop. It was all his fault, if he only listened to his sons and stopped. His sons died because of him. He really was a terrible person. He could have stopped this...
He was angry, so angry. He wanted his sons back, he needed them, they were all he had. He was once again the last of his kind and the pain was so much worse this time; he'd lost his own children.
The human reset once again.
Again and again, pacifist, neutral, genocide. They wouldn't stop resetting, even the pacifist was too painful; knowing it would all reset again anyway and his boys' happiness would be short lived. Their happiness would be stripped away for nothing more than a human child's whim all because they were bored. They played with people's lives as if they were toys.
Gaster could do nothing to stop it. Nothing.
He saw everything again and again, everything the human did, everything the flower did, everything that happened before the human, never anything after.
It was an anomaly, it was forever.
Wingdings Gaster stood in The Void, screaming and crying and with a blaster firing... He wanted out.
