Dean couldnt believe his eyes. Not far in front of him, his dear Castiel layed on the floor, in a pool of his dark red blood. He went into shock quickly, not wanting to believe what he saw, refusing the fact that his angel was dying right in front of him, and there was nothing he could do.
Castiel watched in horror as the room began to grow dark. It had happened so fast, he didnt even think. The moment he saw the gun pointed at Dean, his Dean, he was overcome by adrenaline. Before he could even begin to think, his body had already carried him in front of the Winchester, stopping the 4 bullets that had been fired.
Dean fell to his knees beside Castiel, tears already threatening to spill down his face. He slowly shook his head, as if trying to expel a dream, a nightmare. He lowerd his head onto Castiel's chest, whispering a stream of 'no's', and clutching onto the only thing he couldnt bare to lose.
Castiel drew weary. He knew he wouldnt be able to hold on much longer. He pulled Dean into a hug, ignoring the pain of his body's protests. He met the teary, olive eyes with his own, and offered a weak, yet somehow reasurring smile. Castiel opened his mouth intending to speak, but all he could force out was a mangled cough. Castiel settled instead for leaning forward, and pressing his lips lightly to Dean's, hoping Dean would understand what he wished to tell him.
Dean did understand. And when Castiel pulled away, Dean burried his face in the angel's neck. He let out a quiet sob, and whispered, 'I love you too, Cas.'
Castiel smiled as he let out his final breath.
