#completely impossible

I've seen people complain that Veilguard changes Solas' motivations. And that's sort of true, but really it doesn't so much change them as just try really hard not to look at them. All of the things we were shown in previous games about the ongoing and serious harm done by the Veil still remain completely true, it's just that Rook is never allowed to ask or think about any of this stuff. Which is frustrating because it significantly weakens Rook's character: they end up coming off as determinedly ignorant and uncurious.

Take the information we're given about why taking down the Veil is bad - which seems entirely limited to Varric's claim that it would 'drown the world in demons.' Rook is constantly parroting this line, treating Varric as the ultimate authority on the matter. But this claim makes very little sense, because it surely cannot be the case that Solas wants to create a world filled with nothing but demons. From Inquisition we know he's greatly distressed every time a spirit becomes a demon, so that can't possibly be the outcome that he's expecting.

Of course, Solas could be wrong; he's certainly been wrong about many things before and he's not thinking very clearly. But even so, why on earth would we take Varric's word over Solas' here? Solas is an ancient and knowledgeable mage, the only person around who lived before the Veil, and he literally made the Veil. Whereas Varric is not a mage, has never studied magic or spirits, and is canonically frightened of the Fade and spirits: in the Lighthouse he mentions several times that he finds this 'Fade shit' weird. How could he possibly be in a position to know better than Solas about what would happen if the Veil came down?

Maybe I as a player can just accept that because Varric is The Narrator he must be right about all this. But Rook doesn't know that Varric is The Narrator. So it just feels like Rook is either incredibly ignorant or so devoted to Varric that their ability to think for themself has completely shut down. It's such an odd, anti-intellectual, anti-expert framing: don't do research or talk to anyone who has knowledge on the matter, just accept unquestioningly what your friend says.

Equally frustrating is the absence of any critical thinking about Solas' reasons for doing what he's doing. The only thing Varric and Harding tell Rook about this is that Solas is doing it because the ancient world was beautiful, but what does that mean? And is it really plausible that Solas is doing all this just because of aesthetics?

Rook hears Solas say 'The Veil is a wound on the world,' and never once thinks to ask - what did he mean by that? A wound is something that causes harm, that causes pain. What is the Veil harming? What pain is it responsible for? (From previous games we know the answer, of course. It's harming spirits, mages, and perhaps elves. But Rook never bothers to ask Solas, or to ask anyone else, or even to try to think about for themself about it.).

There's a moment right at the very end, where Solas is finally permitted to mention that he's doing this partly for the spirits. But in a perfect encapsulation of their whole dynamic, Rook immediately interrupts him. Doesn't even let him finish his sentence. Rook is so completely confident that they know best for the spirits and that this person who literally was once a spirit couldn't possibly have any insight into the matter.
