"He's the only person on the planet more irritating than you, and the only one here powerful enough that I can't just ignore him." She'd tried. She had definitely tried. When Dean came to drag her out of bed, she snapped at him until he gave up, but she could have just as easily sent him packing with a blink of her eyes. If she really wanted to, it wouldn't be hard to keep Crowley away from her. There was really no one who could make her do anything she didn't want here, with the exception of her big brother.
But Crowley wasn't wrong. Anna let too much of herself rest on Gabriel. She'd done it in Heaven and it was the catalyst for her Fall after he left. She was doing it here and it was just serving to make her more depressed. She hated to admit it, and wouldn't do so out loud, but Crowley was right. But, of course, she wasn't going to tell him that.
"No one pushes me, Crowley. I very clearly make my own choices. I am who I am because it's what I wanted. I just don't have the patience to deal with some people." Which, surprisingly, didn't include Crowley. What kind of twisted world had she created for herself? It just felt like it was a continual downward spiral, and sinking was a lot better than fighting to stay above water at this point. And possibly more fun. So far it had been more fun.
