Swap's Pov
Papy had been acting so happy since yesterday, I wonder if he had gotten himself a partner. But I also felt that something was off, something was wrong with Error and the multiverse.
I suddenly heard the front door slam open with my brother, drunk of his rear end coming inside with some of the other sanses and paps. They began to speak in slured speech to each other. Red said,"*Hic* Gre-great jobz everyboby. Wes finlly killed the menstrus Er-error." They began to laugh at this more as my anger began to grow.
They thought this was a good thing, there needed to be balance. I need to contact Nightmare and his gang, they need to know as well as the charas and frisks. The others need to pay. I used the special mirror that Nightmare used to contact the others. They answered their mirror and told them all to go to Nightmare's castle. It was an emergency.
A few minutes later, everyone had arrived at the castle. Kitten( swapfell chara) asked,"What's wrong uncle swap? Why did you call us all here?"
"Yeah Swap, what is the emergency?", Terror( horrortale pap) asked concerned.
"As you all know, none of us have seen Error in a few days and I now know why. The "good sanses and Papyruses" killed him."
When the others heard this news, all heck broke loose. The charas snd frisks had begun to cry, while the  nightmare gang looked ready to kill all the"good guys". I didn't blame them, Error might have been a destroyer, but he was kind and wise. He would make toys and teach the charas and frisks to defend themselves. He never judged them for their actions. Error always looked out for us and healed us. We were his and he was ours.
Then through the chaos, Nightmare yelled,"Everyone quiet down! We need to think of a plan for revenge!"
Everyone was quiet after that. Normally I wouldn't agree to revenge, but they had gone to far and the balance was destroyed. They had to pay for their actions and I knew that we would all enjoy it.

Nobody's Pov
The "good guys" had returned to their headquarters, Ink's house. They were starting to sober up when the doors burst open revealing the nightmare gang, Swap, and all the frisks and charas. The goods jumped in surprise, they didn't know why Swap was with the "bad guys". Even the peaceful charas and frisks were there, anger clear on their young faces. All of them had their weapons summoned, including Swap and his gaster blaster war hammer.
They rushed towards the goods, eyes and sockets full of rage and sadness. The goods finally summoned their blasters, bones, and weapons as the "bad guys" got within striking range to their bodies. Swap swumg his hammer at Honey, cracking his brother's skull and ribs. Nightmare went straight after Ink and fresh, ready to kill Error's main tormentors. The gang, charas, and frisks went after all the others, beating them within an inch of their lives. Blood and dust from the broken skeletons filled the house, staining the floor red and gray. Finally Dream spoke, his voice hoarse from the pain of his broken body and sadness from Swap attacking him. Dream said,"Why Swap, why would you attack us and your brother with the bad guys? We are your friends. Did they force you?"
Swap answered,"No I attacked you of my own free will and I did it because you killed Error, my best friend."
Reaper responded with,"We had to. He would have kept on killing everything. There was no other choice."
This got Killer's magical blood flowing. His anger finally boiled over and he yelled,"Error had to destroy things, you incompetent children! In order for our multiverse to not overflow and destroy all the Aus, Error destroyed them! You all killed the only one who could keep us safe amd alive! Ink can't destroy while Ais and neither can we! You have doomed us all!"
The goods went silent as they processed this information. They thought how that explained the fact that Error didn't destroy every Au, even if he had the power to do so. They all had just killed the other half of the balance and doomed the whole multiverse to destruction. They had really messed up. What would they do now?

Destiny's Pov
After beating the fear of myself into my husband and making him sleep outside for the next year, I decided to check up on Era's friends. I saw that they had attacked the goods and were telling them of what they had done. Though I was happy about the giids feeling guilt and pain, I knew that they would now try to resurrect Era. I could only hope that they could never find out that she was alive and try to find her. This multiverse didn't deserve her. I just wish that I could save Era's friends, but I knew they would never survive the trip into the void. Oh Era, I hope you have found a new family and friends to help you heal.
