Some disturbing imagery in Chapter 5--Percy, both past and present, is VERY ambitious, and her present self ends up defeating her past self, it is implied, by eating her and forcibly integrating her into her present self, which psychologically transforms her. Seeing as the past self is threatening to put Leeds in slavery to resurrect her career, and Percy's entire character arc is about reconciling her past, gifted, wizard self with her present, "broken," superintendent self, fighting herself every step of the way, this seems thematically appropriate. The whole message is how about that socially-approved, gifted self, however superficially desirable, is not a nice person and no longer who she wants to be. Percy is basically a fallen mean girl having to put her life back together.

At the start of the comic entire, Percy and Leeds don't get along. A theme of the comic is that beings like Leeds are not supposed to exist, and the ethics of familiars (that is, creating beings purely to serve) are mentioned. Also, Percy has a strained relationship with her father, and a racist ex-boyfriend who is alluded to and finally appears in Chapter 7, which is in progress at time of this writing.
