That's quite a lot of assumptions that are not backed up by anything in the source material. It's one thing to guess what a character might be thinking, but making up whole never before seen abilities on the basis of "well, he's strong so..."? Are you really that deperate to win an online argument? Look, I'm not getting involved in a "power level" doscussion, so let's stick to cold, hard logic: assuming you yourself had all that power and control you attribute to Bruno, would you risk launching a hail of sharp icicles at you youngest son, when you could have just grabbed him by the scruff of the neck and pulled him out like a spoiled child? Just because "I'm good enough not to hurt him too bad"? If the anwser is "yes", would you still expect to be treated like a sane parent? Because that's far from sane, man. As for Palle himself, if you insist that he was certain Falma could not take it, then the only possible explanation is that he wanted to murder him. Is this what you're trying to say? Well then, while that would be an interesting story hook, it doesn't really seem to go anywhere. Or is it that in your mind Palle is also able to somehow cull the murderous power of "tidal wave attacks" right before they obliterate his brother? I'm getting confused here...
Is it that hard for you to imagine that what Palle, a
student (your emphasis) can do (in this case, lethal spells), a grown up can do "better"? Is Bruno not an adult? Is he not
the head of the family? But fine, let's ignore the power scale/level arguments.
Bruno was distraught over two things: that his son just suddenly claimed to be able to cure the queen of an incurable disease (potentially dragging their entire family to the gallows/guillotine should he fail), and (soon after that) the suspicion that his son is not his son anymore. In a world where evil spirits exist (confirmed via head priest) and can in fact possess people, I think it is still reasonable that he would want to disable a possibly possessed Falma without risking getting too close.
As for Palle, no, "wanting to murder Falma" is
very abundantly clearly not the only explanation for his behavior, and I'm sorry if you can't see that. There are plenty of IRL cases where teachers and instructors have harmed a student because they underestimated their strength or misjudged the physical condition of the student, or something similar. Palle is
arguably doing something like that, except 1. he's not even a proper instructor, and 2. he's overcompensating and pushing
way too hard because of the progression of his disease is making him hyperfocus and fixate on "preparing" his siblings for when he's gone. It's sad and unfortunate that he's dying, and wanting to train/prepare his siblings is well-intended, but the way he's going about it is abusive and borderline homicidal.
Did you read what I said? A modern scientist's mindset is not at all what you'd find at anytime before at least the XIX century on Earth. Unless you assume that the story is set in a renaissance period specific culture to just be fluff, and their society full of anachronisms, then it doesn't make sense to expect that from their scholars. Read up on how eager the "academic" society was to consider radically new ideas in the past. Also, what the hell do you mean "strangers with an agenda"? That sounds like some conspiracy theory BS. The facts were that people were either dogmatically opposed to the ideas in question (like heliocentrism) or just thought themselves beyond reproach by some "greenhorns" on account of their authority. That's pretty much it.
And yet the queen, Bruno, the scholars, the pharmacists, heck, even the clergy are accepting all of the new information, tools and techniques Falma is providing without anything near the level of dogmatic rejection your fixation on IRL scientific history would suggest. In fact the only individual actually displaying that level of rejection that we can see so far would be Palle. (The pharmacy guild rejected Falma more over economic rivalry than academic disagreement. The church initially rejected Falma due to the same suspicions as Bruno -- evil spirits. Bruno rejected because "he's gonna get us all killed" and "what have you done with my son". No dogmatic/academic rejections so far IIRC, except for Palle.)
Do tell - what would you consider "non-RL logic" in the context of this story? The little bit about Bruno's supposed abilities? Because you're adamant about me missing the point however, you either don't actually read what I say or your idea of logic is otherworldly by itself. It's not me who expects old timey quacks to have the critical thinking skills of a contemporary person with a science background, remember? So stop insisting like it's me that introduces anachronisms here.
First, I never even said anything about anachronisms, you're the only person here using that word. But since you brought it up:
this whole story is a giant anachronism, only being "plausible" because it's an isekai to a world with magic, gods and spirits -- something your insistence on RL scientific history is not accounting for.
Second, when talking about otherworldly story, use otherworldly logic. Is that too hard to understand?
I already said that if they resort to the "god" explanation, then it's the same as telling him everything, since it only raises more questions that have to be addressed. I'm not saying that it's bad to tell him, they probably should. However, for whatever reason, they're unwilling right now and trying to power through on confidence alone - which would only ring more alarm bells in any rational person's mind.
No, it probably won't raise too many questions -- specifically, it might raise more questions for you, the reader, but not the people in the story. Gods descending into mortals is a known event in this world; Falma is not the first Chosen/Avatar/Incarnation, and (I suspect) the head priest would be more than happy to explain things to Palle. Heck, even Bruno, once it was confirmed that Falma is the avatar of the God of Medicine, took that fact in stride. But a lot of people, myself included, suspects that the author is likely forgoing the much more simple routes to milk this unnecessary drama. And so the story goes that Falma is unwilling to expose his avatarship status, especially to his brother, and we wind up with this bonkers arc.
Finally, I'm probably not going to respond any further; arguing with people about a fictional character in a fictional world is far too draining for my own good. Have a good day, and take care.
