I'd kinda like to keep her change the same. Also, I don't mind you fiddling around with chronology for effect, in general, but Zoe's change is part of the setup of a few early storylines; in particular, if she's not changed, and she and Jon aren't out camping, how do they meet Maxwell coming back?
I guess my line of thought on it is that, yes, she's not a particularly crucial character, but I don't know that she has to be; like Jon's parents, she's just kind of in the background most of the time, but part of the setting of Jon's home and family...
