Sometimes Castiel would just sit by Dean's bed and watch over him while he rested. There wasn't a particular reason for it. Mostly it was just to pass the time. The angel enjoyed studying Dean's face. Each freckle and blemish that he has counted almost a hundred times over. Castiel loved when – very rarely- Dean would just smile in his sleep. It means for a short while the hunter was at peace. The angel was always in constant awe by how much Dean surprised him. Castiel was amazed by; despite surviving impossible odds and losing nearly everyone he loved Dean could still smile at all.
"An impossible man." Castiel whispered almost inaudibly. When the angel rebelled he had no real plan and in essence terrified. Despite this, even if he had the option to go back and do it again; he wouldn't. He wouldn't give up the days with Dean or the emotions he started to feel because of it; such overwhelming emotions all of which are still so alien to him. Each day he discovered some joy in life he never knew existed. Castiel doesn't remember exactly when but all of a sudden every emotion he felt connected him to Dean in some way. Whether it was friendship, worry, jealously or even love. Love is the emotion the angel can't seem to grasp. It was so strange, and complicated. Love seems like such a small word to explain such an enormous thing. Castiel sometimes felt unworthy of such an emotion so he never truly dwelled on it and most certainly never act on it. The only time he shows his love for the hunter is when he takes a few hours each night to count the freckles and blemished on Dean's face.
