The original concept for "Ex Post Facto" was going to see Faith tracking down and dealing with a rogue Slayer – a girl who was most assuredly not using her powers for good. About the only thing that survived to the final version of EPF was the fact that it was Faith-centric. When I sat down to actually begin the episode, I realized that it wasn't working. At all. In any respect. I'm really glad that it didn't for a few reasons. The primary being that really, our Big Bad for the season is all about Slayers abusing their powers. It's not the focus, but it's definitely an aspect. The second reason being that I was forced to completely rethink EPF, and I think it's a much, much stronger episode as a result.

The scene below came to me as I was trying to force the episode into cooperating with me. I got this flash and saved it in a separate file, in case I decided to go with the original episode concept. Didn't happen, but the file survived, and now makes its way here. And I find it amusing that this explanation is bigger than the scene itself.
