The second Anna saw that smirk on Crowley's face, she wanted to turn around and disappear. She wanted to turn around and go right back to her bed. She didn't have it in her to put up with his crap right now. She didn't ever want to deal with him, but especially not lately. Still, she knew that if she headed back to her room this soon her big brother would drag her out by her hair. And it was probably better to deal with Crowley than to risk dealing with Cas or Dean or Jo.
"Your depth of concern is flattering, Crowley. I hope you don't think we're on a level playing field just because I'm a renegade." Anna crossed her hands over her chest, She wanted to be irritated with him, but he wasn't being nasty. It was actually lighthearted teasing. She wasn't sure if she was shocked or irritated by it. At the moment she was going with nonchalance.
