Wonderful, fascinating story, and such an interesting discussion! One thing that I don't believe has been emphasized here is that she pretty much says outright that she's brand new at being a preacher, and she's not terribly comfortable in the role. When she accidentally witnessed the ritual funeral, she immediately snapped back into warrior mode and had to actively talk herself down. So, every time she did something that a more traditional preacher/priest/pastor probably wouldn't or should do, I just attributed it to that.
One of my favorite parts came when she realized that she could be doing charity work. (Coercing food out of the restaurant was one of those "good intentions... interesting methods" moments). I love that to us it makes perfect sense that a preacher would do charity work, but to the Teddies this was very much outside their understanding of her purpose. I was hoping for the story to go more strongly down that path, but it was still lovely to see this thread of the story.
