I mean, I'd say the exact opposite there? Her subconscious self explicitely help Alicia understand how you can twist seemingly insignificant changes into major changes.While to an extent, I get where you're coming from, realistically, Aura simply has hard limits to what she can actually do on Earth. Also, as said before, she doesn't believe that the stuff on Earth is important. There's no magic on Earth and there's no direct connection between the actions on Earth and the actions in Roya. Not to mention that, as established during the prologue, killing Richard on Earth would just ensure that he's the Demon Lord full time in Roya and solves absolutely nothing. The same applies to Luciela. Even if she absolutely proved somehow that Alicia was Luciela, it wouldn't really change much... at least in her mind.
It's also established from the get-go that Aura is... quite frankly... a bit of an arrogant idiot. Her subconscious self exemplifies this clearly when she meets Alicia. For all that she's book-smart, she's not actually all that smart in the people sense. The idea of gradual, seemingly insignificant changes to her mind feeding into major changes which then feed into the complete alteration of her self doesn't occur to her at all. Even though that's really the first thing that she should have thought of.
In general, Aura exhibits a tendency of being really stupid about some things...
As in, she is arrogant enough to think that no matter how major the changes are, it wouldn't matter, because she'll always win, and she is... kind of right?
But said Arrogance should also means she tries to investigate both Alicia and Richard in real life. Anyway, I get why the game apparently didn't do it, just highly disappointed.
As mentioned, all of this is imo kinda more ambiguous, as Aura immediately think there is going to be a trap, and takes it into account, she just values helping to save as many people as possible as fast as possible more than, well, taking care of the trap first.Which is... tbh... fairly consistent with a teenager. They're often dumber than they think they are and this definitely applies to Aura. If she was actually as smart as she thought she was, there would have been plenty of ways for her to foil various parts of Richard's plan from the prologue itself. I mean really... not even suspecting a trap and walking face-first into it was amazingly dumb... Accepting that split-up was also amazingly dumb. If she played things smart during the prologue, odds are that she could have saved at least George, leaving her with one full powered companion even if everything else went the same, which would have changed the equation completely.
If/when you do a corruption playthrough, or just add in corruption as you push towards murderizing Richard in Roya, you'll see that as the mental changes pile up, Aura gets confronted about said changes at certain points, and she completely dismisses the possibility that those changes are in any way related to the Curse. In her mind, the Curse and its changes are only linked to Roya, not Earth, and the idea that Luciela might be spending her time to turn her into a monster on Earth specifically, or where that might lead, just doesn't click.
As for her friends on Earth... I can get why Aura didn't involve Rose, after all, she didn't have anything to really prove her experiences in Roya. However, she DID have something for George, because George tells her something in the prologue that he never did on Earth, and talking to him about it would have been fairly solid proof that something fucked up happened. That said, she didn't want to worry him about it all when he was so busy with his family, and when he was powerless to do anything from Earth while she kept going to Roya every night. It's a reasonable impulse tbh... but obviously stupid given the circumstances.
Both Rose and George imo have very easy ways for Aura to involve them, and she very much knows how important talking to people and influencing them on earth can be to win on Royan too (she does think about it iirc). It just... never goes anywhere apparently.
Re: the brainwashing/curse, I thought people mentioned that there is a part of the curse that means her real self can't actually admit it works, probably a left over from Dolus stuff.
