This is not the only time her tendency to both dither and to draw an incorrect conclusion have made a mess of things. After all, given how she's too stupid to know when she's lost, it shouldn't shock us to learn that she'd regard a victory as a humiliation. The best example of that is when she decided to give Kortney yet another chance despite the crazy, made-up story her obviously jealous Martian creature daughter was telling about how someone who flattered her was a bad person. The dumbass regarded Moira's act of saving her from her own gullibility and need for praise as a humiliation so great, she couldn't work anymore.
Since it's clear that Liz is just as smart, just as brave and just as able to make good decisions as her mother, it's sort of obvious that she's also standing there waffling about what to do about easily soluble problems.
