Here's the Day Four Whumptober prompt which was "No, stop!" This one is a variation to the scene in 11x3 "The Bad Seed"

Also, if anyone has any suggestions for the prompts "Poisoned" "Kidnapped" "fever" or "Stranded" like, characters or situations, let me know :) Those are the last ones I need to play catch-up on.

4. "No, stop!"

All Castiel felt was rage. It boiled inside of him like a fire he wouldn't put out. Anger, fury, hate, and worst of all the pure and animalistic need to kill.

The man gave a shocked yelp as Castiel charged him and tried to run. But Castiel kept going, grabbing the man by the back of his coat and picking him off of his feet to swing him into a pile of crates nearby that toppled and half buried the man. He groaned, weakly shoving at the crates in an attempt to get away, and Castiel began to throw them off of the man, his prey. He growled as he unearthed the cowering figure.

"Cas!" the man cried before Castiel was dragging him up again and throwing him against a wall. "Cas, don't!" The man's hands tried to clutch at Castiel's arms as if to keep him away. He growled again, and punched the man in the face until he stopped talking, then shook him until he let go before throwing him back against the wall.

The man groaned and slumped to the ground where Castiel began to kick him. He caught him in the stomach and ribs, before the man curled up with pained grunts, one hand held up to fend him off. Castiel snarled and grabbed the hand by the wrist, twisting it until it snapped.

The man howled and started to drag himself away, but Castiel couldn't have that. The rage inside of him called for more blood. He didn't understand why this man was so hard to kill.

He kicked out at his prey again and the man rolled a few feet, landing sprawled on his back, groaning but motionless. Something glinted inside of his coat and caught Castiel's eye.

Castiel growled again low in his throat, stalking toward his fallen prey. He bent and retrieved a long blade from the man's coat. His fingers tried to stop Castiel from taking it, but his prey was now too weak.

"Cas…don't, please." The man's eyes were barely open, his face beat bloody. The sight of the blood made adrenaline pump through Castiel's veins and he growled again, clutching the blade in his hand and staring between it and his fallen prey. He needed more blood.

"Come on, man," his prey spoke again. "This isn't you, it's a spell! Fight it, Cas!"

The man would not shut up and Castiel didn't want to hear him talk anymore. He only wanted blood. He growled again and kicked the man fully onto his back before crouching over him, raising the blade.

"No, stop!" the man pleaded. "Please. Cas, it's me, it's Dean. We're family."

Family.

Some jarred in the very back of Castiel's mind. This man's face, and another. Dean. His mind supplied, and Sam.

His family.

The bloodlust fell away, the pounding in his ears ceased and Castiel gasped, coming fully back to himself. He threw the blade away from him as it clattered across the floor and then scrambled off of Dean.

"Dean?" he gasped, fully taking in the man, his best friend, lying on the ground. His face was covered in blood and he was cradling one arm to his chest. "Dean." Castiel breathed, reaching up to clutch a hand in his hair, horrified at the fact that he had done this.

"Cas? You there?" the hunter asked cautiously, eyes wary.

Castiel took a shuddering breath and reached out to touch Dean's shoulder. He flinched slightly at first, but relaxed as he watched Cas' eyes. "Oh good, it is you."

"Dean I am…I am so sorry," Castiel said.

Dean propped himself up into a sitting position and reached out to grip Castiel's shoulder with his good hand. "You dug yourself out of it, that's all that matters."

"But I hurt you! I did…I did all of this!" he gestured to Dean, horror fighting against the spell that still wanted to take its hold.

"It was the spell," Dean insisted. "You can't blame yourself. Now come on, we have Rowena with us, and she'll get you cured."

Castiel shook his head, feeling the spell start to encroach upon him again. He staggered to his feet. "No, Dean, just go. I can't…I can't stop it."

"Yes, you can," Dean said firmly, biting back a grunt as he also staggered to his feet and approached Castiel. The angel held up a hand to warn him back, but Dean just stepped forward and grabbed his wrist, holding onto him tightly. "We're family. Remember that."

Castiel took a shuddering breath. One side of his face was bloody and already swollen, injuries caused by Castiel's own hands, but Dean was still trying to get him to fight this. The heat surged through him and he growled, clenching his teeth, but he shook himself firmly and forced it back.

"Got it?" Dean asked.

"Yes," Castiel replied.

Running footsteps could be heard and Sam and Rowena appeared. Sam had a gun to her and looked shocked to see the state Dean was in.

Dean turned to the witch. "Fix him. Now."

She rolled her eyes but started chanting the spell. Castiel felt it take hold of him, felt the spell being ripped from him. He cried out, collapsing onto his knees as Dean called to him. He felt a hand on his arm, grounding him, and then finally it was over. He lay there panting, and now two voices spoke, worriedly, above him.

"Cas?" someone shook his shoulder; another hand slipped under his cheek and raised his head from the concrete floor.

"Come on, man."

He blinked and saw two pairs of worried eyes staring back at him, one from a bloody face and one not.

"Hey," Dean said as he and Sam helped him to sit up. It was an effort Castiel didn't think he was ready for, but their hands didn't leave him, keeping him upright.

"You okay?" Sam asked worriedly.

Castiel looked between them, memories of everything he had done since the spell had taken hold washing over him, before they culminated in the vicious beating he had given Dean, the evidence of which was still on his face.

Castiel's own face crumpled. "Dean, I'm…I'm so sorry," he whispered.

Dean suddenly drew him into a hug and Sam's large hand settled on the back of his neck. Castiel gave a huff of surprise before he let out a pent up breath and relaxed into their hold.

"It doesn't matter now," Dean said. "You're good. Now what do you say we go home?"

Castiel nodded. Yes he would like that very much.
