Lynn has written that the original inspiration for Connie was an art teacher of hers. She didn't adore her--she ridiculed her by mimicking her and drawing caricatures of her. I was going to have Connie allude to Elly filling a notebook with mean doodles of the art teacher, but canned that in favor of the 'Allo-girl reveal. But here's the between-the-lines/panels bit: Elly is lying in panel two. :)
This strip is meant to pick up from the "Mith Campbell! Michael Patterthon's bothering me" strip that originally came right after the "egg breath" strip. I realize that this makes it highly likely that Lynn will insert some new-runs in between.
Edit: Yay, I'm actually in sync with the reprints.
