Anna never saw Cas as trouble. In anyone else, his constant need to avoid conflict would have driven her crazy. Crazier. Whatever. But it was a relief to see that in Castiel. It made her feel more secure about his well being. If he wasn't throwing himself into terrible situations, she wouldn't have to worry that he was going to get hurt. And it didn't keep him from staying where she could keep an eye on him, so it wasn't a problem.
"You weren't trouble. And we're out now. We just have to stay under the radar. As long as they don't find me again, it'll be okay." They could be safe. If she was out in the world, she wouldn't have to worry about being locked in a room with a demon trying to kill her or worse. And if Cas was here with her, she wouldn't have to worry about them getting to him.
Anna got up and moved toward the phone, flipping through the little "welcome to our motel" book. She was starving. Hungry for something they never served in the nuthouse. "You want some Chinese? I'm hungry."
