I just made a long post in my journal about QAF and Brian and all that, although I didn't say everything I wanted to say. In fact, I think I talked about other stuff so much I got tired out before my main point, and didn't really discuss it very much. But I still figure maybe some of you guys would be interested in reading it.
It's here. Contains discussion of, and thus spoilers for, things up through the end of S3.
