The Cave
"You're empty Castiel." Dean's words echoed in his ears. "There's nothing there! You're a hammer, that's all." The words sounded twisted, wrong. Not like Dean at all but that was his delusion, his penance for what he'd done. His free will was slowly choking him, the noose tighter with every action he did.
Dean was worried. He had been angry, he'd said things he hadn't meant. Cas had just left though, no retaliation, just acceptance. "Please, Castiel. I'm sorry, we need to talk, I want to apologise to your face, not to this emptiness! Come on Cas!"
Castiel heard his prayers but that did not mean he would answer them, let alone go to him. Pleading whispers filtered through the angry shouts surrounding him like a fog. "I'm sorry Cas, please. I- I just hope you're okay." Castiel blinked, startled. Dean cared? Why? Castiel was nothing but a weapon to him and Heaven. What use did a broken weapon have to anyone? But broken things could be fixed, maybe this was the way to fix him.
Dean sighed and opened his eyes, no luck, Castiel was nowhere to be seen. He covered his face with one hand. He didn't hear the flutter of wings behind him but he heard the deep voice saying his name. He jumped up from the bed he had been sitting on. "Cas! Where were you? I wa- We were getting worried!"
"I'm sorry Dean." Cas ignored the taunts sounding around him. "I had to be somewhere."
Dean hung his head. "Away from me." He whispered but Castiel heard anyway. "Cas, about what I said, I'm sorry, I was drunk and angry and- and-" He spoke frantically but stuttered to a stop as Castiel stepped closer.
"It is fine Dean, it is forgiven, Now let us "Forgive and forget."" Dean smiled at Castiel's use of air quotes and the voices faded to a low whisper behind him, shadows dispersed by Dean's sincere apology and the light of his smile.
