Castiel held his arms by his chest as he stared at Dean, who was choking small sobs out. His eyes widen and his voice stuck in his throat. Room around was mess. Table broken, chairs in pile by wall. Castiel was witness of all this. Of Dean's deep sadness. Of his bursting out. And he watched Dean silently, his eyes filled with sorrow.
"Don't look at me with those eyes" Dean suddenly spoke with husky voice and he slowly looked up at Castiel with dark eyes. Anger was still bubbling inside him. But as he met scared eyes for an angel he always loved, his breath hitched a tiny bit. What was he becoming? Scaring ones he loves. Cutting them off. Killing them.
Castiel took step closer and Dean looked away. "Castiel. Never. Never, you hear me - Never ask me to believe into god, you yourself don't believe in" Dean slowly got up and Castiel swallowed lump in his throat. "Dean.." Castiel said quietly, his voice quiet. "It wasn't your fault.." He said softly.
"What? That Sam died?! That Bobby died?! That Charlie died?! That Kevin died?!" Dean said and his hands began to shake. He scoffed and he curled his hands into fists. Castiel walked closer to him and rised his hand.
"Don't" Dean said. "Don't try Castiel" He said and shaked his head, fighting heavy tears. Castiel hesitantly nodded.
"Dean. If you will ever need me.." Castiel said but Dean growled. And with flutter of wings, Castiel was gone.
Dean was mourning, drank untill he drowned in his sorrow.
