I agree with this, admittedly as someone who thinks the character is written very badly. The problem for me is that in a world like this one, most people would be off their rockers by now - wildly inconsistent, irrational etc (with the fact that nobody will have their meds anymore being only a small part of it). Yet narrative - actual story - needs to be consistent and organized and coherent; it can only pretend to be chaotic or it loses the audience, who need the comfort of narrative organization.
Agreed, but I don't really see that happening here. Even if Lori is acting a bit strange and conflicted, it's just one character. I don't really see her behavior affecting the story as a WHOLE in any way.
