« Dean,
I know that you don't remember our very first met. But i do.
I saved you from where darkness is king. You didn't want to be saved. You were thinking that you wasn't worth it, that you were in hell for a good reason : Sam.
You were worth it to my eyes. I'd never seen brightest soul before yours and god knows how many souls i've seen. The Righteous Man.
I printed my mark into your soul, so you would never forget that you were worth it to someone. To me.
You've been raised as a soldier with a missing dad. A common thing we were sharing.
At first, you were distant with me, i even thought you disliked me. I wasn't supposed to feel something. I was a soldier with orders to accomplish... Corrupt orders. But something in you was calling me. Something that i couldn't put a word on it. You were broken but fearless, tortured but courageous in any situations. Behind this hidden weakness, something was wrong with you Dean. You were always doing your best to save people, to save your brother, to save the world... Sadly, not everyone can be saved.
In the end, the only thing you were hating that much was yourself.
« How a man can hate himself that much even though all the good things he has done ?» was the only question which i was trying to answer.
Then the years went by and now i know why Dean. All the people you loved disappeared at the speed of light. You're always blaming yourself that everything is your fault. But it's not. People chose their destiny.
I've done wrong choices which seemed right to me. I betrayed you. I lied to you. But it was for your safety.
It was my destiny.
You had the choice to leave the purgatory without me but you made the same choice as me years before... I was maybe worth it to your eyes.
I didn't want to be saved either. I was there for a good reason : You. I sacrificed myself for you Dean. Like i always did and will always do.
You will always be the righteous man for me. »
Cas.
