It felt like Taylor was being really unfair to Lisa here. More than her character would normally allow for, I mean. I mean... thinking worse of her for trying to gain sympathy points to increase the odds of escaping slavery and/or death? Because make no mistake about it, that is Lisa's situation in early canon. That reads less like somebody who desperately wants to help people and be a hero, and more like somebody who completely lacks basic human empathy. So does her feeling absolutely no guilt about terrifying and manipulating somebody even after they've already agreed to her terms.
Honestly she comes off closer to a sadistic sociopath in these scenes than she does a hero with strict morals. Not entirely there, of course, but quite robotic and cruel. There's a lot of "I decided to do this, and this happened so I decided to do this other thing, too" and not very much "I didn't like what I was hearing, so I decided to push a little harder." Factual, but without emotion.
Additionally, it doesn't fit with her actions in other parts of the story. I mean, here she is, trying to be a hero, trying to help people. She's already wracking her brain trying to figure out how to get Amy and Vicky to accept her help, just because she saw they have problems she could help with... and here's somebody who is legitimately asking for her help, admittedly after being caught with her hand in the proverbial cookie jar, and her entire mindset is focused on making it as onerous and burdensome as she can for the person asking for her help, with clear intent to betray that person in the end anyway?
