I realized too late that I forgot to put some more background people in the library (it's not empty you know). I remember thinking, "You've got a couple days before you have to enter text, so draw some random people in there in that time." That time went by faster than I thought, and background characters completely slipped my mind.

I can come up with an excuse to why you never see the librarian at the desk. She's at the computer at the far end, but panel two only goes as far as the computer, so she's not seen. Panel six, Anthony's clearly covering her up. You guys believe me, right? (laugh)
