Cas wanted desperately to touch him. The flesh and blood was still his beautiful Dean, but what lied beneath was something different entirely. It was dark and twisted. It was horrific, almost.
"Dean, I… I thought you were dead. Metatron told me…"
"Well he was right. Dammit Cas, I'm not me anymore, I'm a monster. Don't you think I can see that? I'm this twisted, ugly monster. I'm the same damn monster that killed my mother. No, I'm worse, I'm a goddamn Knight."
Cas swallowed hard. Never did he think a demon could be beautiful, but despite it all, he was. He was this beautiful terrifying being, wrought with pain and suffering and grace.
"Dean… no…" he choked, trying to find words to comfort the man he would raze heaven and hell for. The man who he had made his entire life.
"Cas, I can see you. The real you. You're this beautiful glorious thing, and I'm just a monster. A horrible, deformed monster." Dean sobbed, hands reaching for his face, fingers ready to claw out his eyes.
Cas reached for him, grabbing his hands and pulling him closer, into a warm, tender embrace. He rested his chin on Dean's head and let him sob into his neck. The smell of sulfur and heat was intoxicating.
"Dean, please look at me." He said gently pushing him away, still clutching his hands. Dean's black eyes met his as Cas caressed his face.
"Dean… You're still beautiful in my eyes."
