"I don't get it Cas, I mean…Meg?" The eldest Winchester frowned into his burger.
"I thought you trusted her Dean." The Angel frowned, "Or would you have let anyone deal with me as long as it wasn't you?"
"That's not fair and you know it," Dean put the burger down, suddenly loosing his appetite.
"You're not being fair to her." the angel looked away, why were humans so…complicated?
"Cas…come on, she's a demon!"
Castiel looked his friend straight in the face, "So were you."
This was more than shocking. Castiel watched as Dean folded all his emotions into his face, hiding them behind his neatly kept mouth, eyes, and nose which never showed a spot of stain. Once this would have hurt the Angel's feelings but he was past that now. The Winchesters seemed to think he was completely to human feelings, but rather it was the why he couldn't understand. Why did humans always get so emotional? Like right now, Dean looked betrayed, hurt, angry, sad. But he always was a few of these. His face was like a work of art sometimes. Equal parts of pain and happiness. Other times, this time, it was horribly unbalanced. A tempest raging beneath that hardened surface.
"What the hell does that mean?"
"What I said Dean." The Angel somewhat regretted bringing up the subject, but it's not like Dean ever pulled any punches. "When you broke, thirty years into your sentence, that was the first step. For ten years the light of your soul became black smoke. It was difficult but when I raised you, I also managed to purify you."
Dean stumbled backwards. There was a moment of silence. Dean was folding up his face again. Finally he asked in a hoarse voice, "When were you planning on telling me this?"
"Honestly?" The Angel looked him over, "Never. but you have to understand that Meg can change."
"No! They can't, Cas!"
"Why are you shouting?"
"Because she's a monster!" The oldest Winchester leaned against the table. He looked very defeated. How many times, how many ways would he have to lose his best friend? "Damn it, Cas, this is just like Ruby all over again."
"I know it may seem like a betrayal, Dean," Castiel took a step towards the hunter, "But you have to have faith."
"Faith? Really?" Dean glared at him, "In what? Meg?"
"In me." The Angel held his gaze evenly, "Please just trust me."
"The last time you said that you swallowed all of purgatory and became God."
"Well you refused that time."
"Why do you love her?"
"Because she isn't that different from you."
Those words should have hurt. They sent chills down Dean's spine every time he heard them spoken, but not this time. "Alright…But she's on probation."
"Thank you, Dean."
"Why do I feel like I'm gunna regret this?"
