A second announcement is that because of developments in season 8, I'm shifting to a twice a week posting schedule so we can get to Prophecy Girl before #37 comes out. I'll be posting notes on Mondays and Thursdays.
Standard disclaimer: I'll often speak of foreshadowing, but that doesn't mean I'm at all committing to the idea that there was some fixed design from the word go -- it's a short hand for talking about the resonances that end up in the text as it unspools.
Standard spoiler warning: The notes are written for folks who have seen all of BtVS and AtS. I'll be spoiling through the comics as well. Basically -- if you are a spoiler-phobe and haven't seen or read it all, read further at your own risk.
