Pretty sure that those in the room will not be aware, for narrative reasons.
The protagonist has ascended a godsdamned cliff of character development in the past couple chapters that would change her relationships with every fucking other character. That's generally not done in the middle of a story like this. (I can't think of any examples where it's done well, but I could be missing things.)
So we should expect that if anyone knows what happened, circumstances will conspire to prevent the protagonist from learning or taking seriously the full scope of her alternate timeline experiences.
EDIT: Also, you should all already know this. You're reading an EarthScorpion story. He means to write well and he pretty much does so. I guess maybe some of you don't know what good writing looks like yet. That's fine. Everybody starts somewhere.
On the contrary--most good stories have exactly this kind of cliff happen, as a marker to indicate that things have changed, and to ratchet up the tension.
Essentially, there are two different methods to drive a story forward: the story can be driven by the situation, with the characters struggling to make do as best they can as things get progressively worse, or the story can be driven by the characters, with the tension coming mainly from their efforts to fix the problems they run into, and to correct for their own mistakes. Typically, fantasy stories tend to favor the second approach, since it usually tends to mesh better with the reasons why people read fantasy in the first place. The problem is declared--in rough outline--early in the story, and then as the story progresses, details are revealed, and the characters find a way to adapt, to improvise, and to overcome. Character development in such stories is sometimes gradual, but in most cases, it will tend to be cuspal--that is, you'll see a lot of character development at once, and then things will even out as the characters try to re-balance themselves with the new character, while at the same time still addressing the basic problem. Then, if that is not enough, there will be more character development, often by an additional character, which will further change the situation. Particularly long stories, or even series of stories, can have this process repeat itself five, six, or more times before things begin to come together for a solution. When that final solution happens, however, it will not happen because the situation has changed, or, necessarily, because the characters have finally gained the resources and the connections to fix the problem. Rather, it will be solved because the characters themselves have changed--they have grown, matured, and adapted, so that they are no longer the people they once were, and so that they can look at the problem from a different angle, and see how things have changed. If you need an example, you need look no farther than
The Hobbit, where Bilbo undergoes two major "cliffs" of character development, which remain with him for the course of the story. Both of these periods of character development are sharp, they are both sudden, and they both provide a dramatic alteration of his character...and they both have a direct, and vast, impact on what happens over the course of the story.
As for Louise, this would mark not the first, but the second, or possibly even the third major character growth. The first came when she first assumed the role of Overlady, when she realized just what had happened to her kingdom, and what was going to happen. This period saw a number of pivotal changes for Louise, including the discovery that she
could do magic, that she was not just the Zero, and that ultimately being a hero isn't about showing them all, but simply about doing the right thing, regardless of everybody else's opinion of you. We have been seeing hints of what she was like without the Evil power throughout the story, but it is only when the evil magic is either exhausted, or simply withdrawn, that we can finally see the true Louise, the one that has been hiding beneath the quite understandable mask of anger, rage, and, often, envy. Louise without the magic is different, yes, but both her rage at the Viscount, and Marzipan, both testify to the deep, abiding connection to her family that she still had--even to Eleanor, with whom she did NOT get along when she was a child. Given that it was already heavily implied that her temper was the result of latent Evil in her bloodline, it should come as no surprise that, with the Evil removed, so, too, is the temper.
The shift will not remain--not completely, at least. Louise will have to take up the Gauntlet again, and that will mean that she is infused with Evil energies once more. This will, as we have seen, affect her personality, and likely make it very difficult for her to act on the feelings that she now has no choice but to acknowledge. The primary effect, I would expect, would be on Eleanor, who will finally be able to lance that aching bitterness that has tormented her for so many years, and possibly on Magda, although I rather doubt that.
I can understand why it would be fairly easy to miss these signs. Moreover, I will not be surprised to find out that I am wrong, and that EarthScorpion does have something different planned for character development. But the indications leading up to this have been there throughout the story. This is not a cliff, nor is it a tomato surprise. It is something that was broadcast for at least twenty chapters prior.
