The word "xsa" is Drow. As in, the language of the dark elves (also called Drow, if you didn't know that) in Dungeons and Dragons. The fact that Petra chose to use it and not just outright say the word "damn" opens up some odd possibilities. Coupled with what she says in panel 2, it's an odd combination.

Oh, and Petra is totally working while talking, hence her holding the posters. In retrospect, I should have had a shot of her stocking the shelves. Instead, I opted to stick with Julia all 4 panels just to do the poster in the background.

Anyhow, tomorrow will be a little flashbacky/expositiony sort of thing, so this means I can deviate a notable amount from my normal drawing methods. We'll see how that goes...
