Yay! Comics fic! I swear the fanfic that'll come out of this storyline is the main reason why I'm not flipping out over Buffy's pregnancy (though I did have a good flip out at about 3AM).

I'm liking how Koh is gaining a personality of his own - we don't have much to go on, but what you do with it makes sense. I love your choice of having Willow's brain narrate the story - have it from Willow's perspective - because it answers so many questions people have that the comics just aren't long enough to answer.
