A somewhat random Dresden Files question

I've been doing a Thomas-centric reread of the series (... so sue me XD) and there's something that's been bugging me for a while.

This journal is a Season 4.5 Spoiler Free Zone (TM), by the way! Please don't mention anything from unaired episodes, promos, etc. Thank you! :)
