(someone wanted this and i was inspired, i like this ship !)
It is a secret for nobody, Killer was in love with his boss Nightmare. And since Nightmare knew, he lived, well, a living nightmare. The Master did not appreciate the feelings Killer had for him, so he hardened the spell over Killer's soul. Since then Killer suffered. He thought about never telling Nightmare because he knew that would happen but guess he cannot fool a guardian of feelings. He had time to regret the love he had for him. He had time to cried out his remorse, and so his Pain. That hurt so much to love someone that tortured you when they knew because it is like a taboo subject.
Regularly, Killer is seen throwing up red glowing magic because how much his soul hurt. Everything hurt so much he could not stop crying. He barely succeeds his missions because he always wants to scream in pain and ravage anything in order to calm himself. He just wanted to die, to end it all, yet Nightmare still arrived to prevent him from killing himself. The Suffering is his punishment for loving him. Killer never knew why he was so dogged in this, he never planned to say to Nightmare his feelings, he never planned to have more than this boss-henchman relationship...
The others wanted to help but, how can they? They cannot ease the spell, ease the pain, ease Nightmare's actions on him. Nightmare is always having fun with the spell, feeding off Killer's negativity and pain every time he can. That is so much fun to see him fighting from screaming in pain in front of everyone, crying more of his goopy tears.
Killer stopped eating, stopped sleeping. Stopped living. It hurts so much to do anything. He is now a full Negative battery working 24/7, lying on a bed. Nightmare was killing him slowly and painfully. That sicken everyone, who despaired to help Killer. Nightmare is happy to have that idea because he never had this amount of negativity since he has them. He had stricken the good one.
Dream, who was aware of Killer's situation during a fight, tried to talk with his twin. It only results a hard punishment for Killer because Nightmare thought he had spilled the bean. But Killer did not, and Nightmare cannot accept he was wrong, so he kept his mind on Killer's betrayal... It resulted with the gang misbehavior since. They could not help Killer, so they disobey to Nightmare... they will have nightmares if it is a solution to ease killer a bit and distract Nightmare the more they could.
Someone, not a Bad Sans but can be considered as one, wanted to act. Hate, because it is about him we are talking about, was planning to kidnap Killer. Nightmare was killing Killer. Hate wants him alive and cannot let him at the castle. He had a plan; he wants to use Killer to destroy Nightmare. Since he cannot use Love, well, must try Hate. If he saves Killer, heal him and grows Killer's Hate toward Nightmare, he can have a great ally. He grins.
Kidnapping Killer was even easier than expected... He was not prepared for what he saw... what Killer was looking like... It was the first time he saw someone mentally broken as far as Killer.
Killer is in a bad state. When he came in Killer's room at night, he saw him laying down on his bed, above the covers, a coffee besides him, all messily patched up by Horror and Dust. He is so exhausted he did not move when Hate came in. He did not move when Hate sat beside him on the verge of the bed. Hate stares at his body, looking at every broken bone, on the ribs, femurs, fibulas, head, sockets... his dull lifeless empty sockets staring at the ceiling, his pales bones, his tears marks on his cheeks as the tears won't stop falling on the bed. He looks so broken, so fragile now, so done with his life. He caresses a bit his skull, very lightly.
"Look at what he has done to you..." Hate murmured.
No reactions. Not even a little. Like he was a lifeless puppet. Oh, he could not let Killer here for another day. He so near the Death to let him here now. That makes him frown before he covers him in a cover. He takes Killer in his arms bridal style lightly to not arm him more. Holy sh... he is so light. How long since his last meal?? While he is thinking, Killer made a movement... his hand had slowly and painfully grabbed Hate's vest. He knew it was not Nightmare, but he also knew this someone was bringing him away since he cannot do it himself. Hope grew in Hate's mind; Killer is still conscious... he still thinks, and he can recognize if he is or not Nightmare. Killer closed his eyes.
