Finally figured out the one little story thing that was keeping me from going on. Though, of course, there are more little roadblocks along the way that I'm going to have to figure out. At least it's really developing the backstory for some of the characters.
The one I just finished up fixing definitely fleshed out Giles' character and made Vera a little more believable. I'll probably have to write the stuff out in my jisho, just so I don't forget. But since it was so cool how I figured it out, I doubt I'll forget it.
