29. Stop

Dean frowned when Cas stormed into the bunker with a pissed look on his face. Something was wrong with his angel.

"Cas?" he said. "What's up?"

Cas didn't answer. Instead, he stalked out of the library and towards the small training area at the back of the bunker. Dean followed him and found him furiously attacking one of the stuffed dummies they'd set up a while back. Dean was surprised; Cas was never usually this mad!

"Cas?" Dean stepped up to Cas and gently grabbed his wrists to stop him from raging. Cas struggled, so Dean let go of his wrists and instead hugged him tightly. God forbid he turn into a sappy romantic but Cas needed the comfort, so Dean was going to provide it! Cas struggled to free himself for a moment but then just slumped in Dean's arms. Dean patted him on the back and pulled away.

"What's up, Cas?" he said. Cas' mouth constricted for a moment before he sighed.

"I encountered two of my ex-brothers," he said.

"What? Angels?" Dean said immediately. "What'd they want?"

"It was a chance encounter," Cas said bitterly. "They found my situation…amusing. They found it funny that I would give up my grace for one human, especially one who has 'screwed everything up enough as it is'."

Dean wasn't surprised that the angels thought that but it still stung deeply that they would say that. He may have messed things up before but he'd always tried to fix it!

"Do not get me wrong, Dean," Cas said. "I don't and will never regret giving up my grace for you. I just –" He sighed deeply. "I was not prepared for the encounter."

Dean put a hand on Cas' shoulder.

"Who cares what those dickwads think?" he said firmly. "I know they were your brothers but family doesn't enjoy each other's pain. Sam and I've said some pretty crappy things to each other before but we never laughed at each other like that."

Cas stared at him for a few moments before nodding. However, his anger was far from gone and after kicking the dummy behind him, he turned and grabbed Dean before kissing him roughly. Dean staggered back, surprised by the intensity and ferocity of Cas' kiss, and he actually winced when Cas' fingers curled in his hair and yanked.

"Cas!" he tried to say but he couldn't talk through Cas' mouth. He could only stumble back as Cas attacked him fiercely again and again with kisses that had moved beyond passionate and into painful. When Dean's back touched the wall, he tried again to tell Cas to stop and even pushed against him but Cas didn't seem to be paying any attention. It was only Dean's head accidentally slamming into the wall and his muffled cry of pain that made Cas pull away, his eyes shining with shock and regret.

"I hurt you," he said quietly. Dean blinked rapidly through the pain, squinting at Cas through the tears in his eyes that had appeared with the sharp throbbing in his head. Cas reached out to cup his face but Dean, still reeling from the shock, roughly swatted Cas' arm away before almost running to the door. He had to get out of there!

"Dean!" Cas called. Dean ignored him as he hurried down the hall towards their room. He slammed the door shut behind him, locked it and fell onto the bed moments before Cas began to knock on the door. But he ignored him.

"Dean! I'm sorry!" Cas said. Dean didn't reply. Instead, he stared blankly at the wall in front of him. He wasn't crying – he really only ever cried in the most serious situations – but he couldn't stop the hurt welling up in him. Why hadn't Cas stopped when he'd asked? Cas had promised that he'd never hurt him but he just had!

Dean drifted into an uneasy sleep, the empty spot in the bed next to him practically burning.
