It wasn't strictly true. Ruby could hide weakness very very well. She made a career out of it. But not from him. Never from him. Azazel had known everything she was, and this, who she was now. She wasn't suprised it disgusted him. It would have disgusted her back then too. But talking about betrayal. The things he was saying she had done. Betrayal, and she couldn't deny any of it. She wouldn't. Not only Sam, but helping fight her own kind. Teaching others how to do the same. How could she have not known that he'd come back, that he'd find all this out. Of course he'd know. She wasn't even suprised when he punched her. "I know it sounds like blasphamy and maybe it is but its true as well. He'll destroy you once you're no longer useful and it doesn't have to be like that. You're better than that. I know I've disappointed you. I know everything I do with Sam disgusts you but I love him. I do. He's...well you know him about as well as you know me, don't you. I should have known you'd hear. I didn't think...All the planning I do for a job from you and I just didn't think this time. I'm sorry, I am. I just want you to see things how I do. See the truth."
And then, so quickly, so easily he switched, changed back to the Azazel she was more used to, the one she'd missed so completely since Dean had ripped him out of her life with one bullet from the Colt. He was being gentle now and she had to admit the truth, "...I missed you too. I know I shouldn't but I missed you and I wish both things were okay, that I could love him and miss you but it doesn't work like that. You can say you'll keep up the lie, but can you tell me you won't see Dean in a few minutes and want to kill him for what he did to you. For a long time thats all I thought about"
His hand was still on her cheek, so affectionate. Fatherly. Wrong now
"...Sam'll be here soon. Let me down. I won't tell them anything."
