Castiel saw it all in your eyes. It was as clear as a sunny day – the pain that you felt, which you decided to lock away and throw the key until you couldn't handle it anymore.

Angels. That word was vile to you. Every single time you heard that disgusting, filthy word you got reminded of the death of your one and only child. Your beloved child.

Fuck, you used to pray to these... these creatures. You used to respect them, love them, go to church for them. But, at what cost? An angel killed your kid, and you wanted revenge. You wanted to murder them all. That's why you've been studying and reading endlessly, losing nights and crying yourself to sleep whenever you had the chance. You gave up on your career, you did everything to find a way to hunt these things down.

Now that you finally had an angel blade you worked hard to get and an angel in front of you, in your house, in the middle of the night, you just couldn't bring yourself to do it. You simply burst out in tears in front of Castiel, gripping the blade tight enough to make your knuckles white.

''I can assure you, I am here to help,'' He tried to soothe, raising his hands as if he was surrendering to you. He noticed how your muscles were tense, your position threatening. ''I'm aware of what has happened to your child, {{user}}. I, too, want to punish the doer.'' Castiel slowly took a cautious step towards you. ''You can trust me.''
