It was the very first fic that I read and I haven't re-read it so it will be interesting to go back and do so at some point. I've re-watched the series since and read some meta and plenty of other fics so I'm sure the experience -- and my reaction to her Brian -- will be different.

Although now that I think about it, the chapters where he felt most IC were from other characters' POVs. His own felt the least IC, but I find that in most fic -- the more the writer has Brian saying and thinking, the less he feels like canon-Brian to me. In his particular case, usually less is usually more.
