What He Saw
It happened in mere seconds but Dean saw everything.
His gut clenched seeing Sam flinch away as he took out the demon-killing knife from his jacket. Sam had only moved one foot and caught his breath – barely twitching a muscle – but he saw it.
When Sam looked down to the knife, he saw fear reigning Sam's eyes. 'My brother called me just to kill me…'
There was no urge to fight as Sam looked at him in the eyes, just total submission. He saw that too and damn! He hated it.
He saw Sam thinks he was going to kill him.
He saw the lack of trust Sam had on him.
He saw that his little brother was afraid of him.
But who was he to question that? He was the one coming up with the 'not able to trust you anymore' thing. He was the one who made himself less human by closing the door to his heart from the most – maybe the only – important person in his life.
Throughout his entire life, Sam was his destiny. He would sacrifice everything for him -everything and anything - including his life for his love towards Sam.
But now he saw Sam's willingness to be sacrificed by him for the greater good of the world – a world that was never fair to them. Sam looked so small and so naïve – so much like the baby Dean used to nurture - thinking unselfishly that his death would mend things.
And for the first time after what he felt like eternity, he yearned to protect him, to be Sam's big brother again. So he took the first step.
He weighted the knife, balanced it in his palm and twisted it around – shoving the hilt to Sam while holding the blade firmly towards him. He hoped Sam gets the message – he was going to protect him from any danger, even if that means he had to put his life on the line.
When Sam grasped the hilt and carefully maneuvered it out of his hand, he saw it.
They were definitely heading down the right road and for the first time after so long, he felt like a big brother again.
