So much for a happy ending.
Sans grumbled, leaning against the mesh wall. Since the barrier had been destroyed, everything seemed to have gone downhill. Everyone had been excited about escaping the Underground, and with Frisk acting as ambassador they surely would have been accepted into the society, even if it took some time. All was well as they left their lifelong prison, enjoying the fresh air.
At least, until they came.
Sans didn't know what they were, but they hadn't been human. Frisk had said something strange about them being from the stars, before they attacked. They were fast, strong, and smart. Then they were herding the crowd like cattle at the cave mouth. Many had tried to fight, but these creatures were not the children they seemed to be. They were outnumbered by the monsters, but when the monsters retaliated with magic, they returned the fight with their own.
It was something no one had seen coming. Creatures as strong as humans, but with magical properties like the monsters. There was no way they could fight them.
But instead of killing them all, they did something much stranger.
They had shot the cowering monsters down with strange weapons. Instead of reducing the creatures to dust, however, it had shrunk them down.
Even now, Sans couldn't understand how they had done it, or what that gun was.
Sans, with Frisk in one arm, Papyrus in the other, had trembled as the creatures began to collect the startled monsters and shoving them in boxes.
'Frisk, now may be a good time to reset!' Sans choked out, dragging the child closer when one of the creatures came nearer.
'I-I'm trying!' Frisk squeaked, face scrunched with concentration, then dread, 'Sans, I… I can't reset!'
The creature had paused when it had seen the child. Smirking, it reached out and pulled the child from the tiny skeleton, tossing the kid in the air a couple of times.
'no! don't you dare!' Sans had screamed at the creature as Frisk squealed.
'Hey Gears! There was a kid in all that!' It yelled out to a figure on what Sans recognized as a motorcycle from Papyrus's books. Red eyes looking on with boredom, he growled.
'And? What about it?' The figure seemed very irritated, leaning against the bike with crossed arms.
'What should we do with it?' The figure shrugged.
'What do I care? Give it to Jetstone,' He growled, looking away, 'Now hurry up and get the last ones!'
Before Sans could rush to help the human he had grown so fond of, he heard Papyrus cry out. Before he could do anything else, he felt uncaring hands grab him and stuff him into a box with strangers. It wasn't long before the boxes were all sent away, and Sans found himself locked in cages with other monsters.
'G'night folks!' Came the cheery voice of the store owner, 'Pleasant dreams.' Its dark eyes seemed to seek out Sans's eye sockets, a cruel grin crossing its lips as it locked up the store. Like I'd have pleasant dreams!
Fingering the band of metal around his neck, Sans wished he could voice the torrent of curses in his head. He wished he could summon a Gaster Blaster to shred the mesh of his cage. But, the collars – that is what the creatures had referred to them as – had made speech and magic nearly impossible.
Smirking sadly, he pulled up his hood, hand protectively wrapping around the sleeping form beside him. Through all the mess, at least he was still with his little bro.
