So I like your explanation that GG hasn't thought deeply about this subject. That's especially true if Amy has been on hand to fix some of GG's over- exuberant arrests. But it seems like she should at least be consistent. The "cardboard" feeling comes from having a few abortive starts at a counterargument
without coordinating those arguments. So as i understand it the exchange is something like:
M: If you want something (anything), go get it
V: That sounds villainous
M: Take proactive steps toward your goals, don't be a doormat
V: helping everybody is the way to be a hero
M: Non-powered people can be heroes and still get paid
V: Parahumans who take money are rogues, not heroes
M/A: Healing should cost money / that might cause problems / (economics)
V: That's unfair!
M/A: (more economics)
V: Charging people to be healed even if they don't need it is extortion
I notice a few things having read that again more carefully.
First, she really ate a lot of Amy's time and i cannot
believe Marquis put up with her interruptions. One or two, maybe, but she got as many or more lines than his actual daughter. This is especially true because she is identified first as
Brandish's daughter.
Second, Vicky's mom is a lawyer, and many lawyers are paid to be "on retainer" so the idea of paying someone to be on-call with a specialized service shouldn't be too foreign.
Third, the distrust she has for Marquis is a good motivator for her weirdly naive first reaction to the self-determination speech he starts off with. And maybe since her version of "helping everyone" is something that she wants to do at all times, the thought Amy isn't as happy about it wouldn't occur immediately.
BUT I feel like putting all of those things in her mouth, one after another, is just too on-the-nose. She had just been shot down several times in a row and acknowledges that she's "butting in" when she interrupts Amy. To have her argue about
unfair pricing structures as something to decide what makes someone a hero or not just feels too close to the soap-boxy lectures of character bashing. You may agree or not but I wanted to give you the idea of where the dissonance is coming from for me.
(I enjoy your work mostly and think that you spend far too much time going back and
changing chapters in response to criticism. Take this as poll-data for the next good scene that you write!
