Hah, thanks so much. I agree about not seeing enough of Liz. I think I was a little overeager to get going with a storyline, so I didn't build her up enough. Also, in the big scheme of the comic, Liz isn't very important, but nobody else has any way of knowing that, so you're totally right.
Also, thanks for confirming what I was afraid of about Cory and Newton... I need to get on that pronto.
