Commentary:
Well I guess that makes two pages in a row where a character makes an exclamatory remark not exactly meant for everyone to hear just as a character leaves the scene. Lubo said something Otto might not want to hear out loud in the previous page.
This page did not require that many actual backgrounds, but sometimes those pages just happen. And we take those opportunities!
