#WritingWonders 8/2: How much do you know about your side characters prior to the first draft?
Usually quite a lot. Unless they're mere voices heard in passing, I have quite a lot of trouble conjuring up a character without getting to know them in my head first, and quite a few details come out in that process. Plus, I use a worldbuild-first process, and so many of my side characters were well-developed in the course of that.
