I think we are aware that some people find Mizora attractive and want to have sex with her. But the fact that you have not one but two lines basically saying:

Maryzora: Do you want to have sex?
Tav: 2 options to say yes, one with doubt and one for sure. Just one very, very polite rejection.
Maryzora: Long description that can be sum up as "But I'm Maryzora, everyone should desire me because of reasons!, just say yes, I would make it easy!"
Tav: Only allowed to say yes or "absolutely not".

Compare that with rejecting Halsin "If I wanted to rut with half a ton of dumb muscle, I'd seduce a deep rothe".

So why are we expected to be nice to someone that we don't want at camp? Why can't we spit on her when she says to wink? Why can't we tell her that, actually, even if we were unsatisfied, what she offers has the appeal of fucking a caustic slime?" or when she insist that "you'll regret it", to tell he that she is delusional and pathetic. That still leaves the option to have sex with her to the ones who want to take it. And would allow for the people who want to support Wyll or simply don't find her attractive to say so. Assuming that everyone MUST feel some attraction to her is denying player agency.

It is already bad that they force on you deals that don't make sense without letting you say "I don't have to make a new deal with you. Period". Ot that "an infernal heart is still a heart and doesn't change your nature". But instead, you are pushed to say a nursery rhyme? really? Sorry, but that doesn't make her clever, just dumb down our character by taking away options. A real infernal trial where you have to prove that in fact, Maryzora broke the deal would have been way more dramatic and rewarding to the player. Hell, they could have had the sex with Maryzora as a reward if you chose to enslave her as a result of her breach of contract.

I'm aware that changing that is not possible at this time, but insulting Maryzora should be easier and possible. As simple as some written lines more. And you can keep the exact same voiced answers by just adding one final line from Tav at the end "You are delusional and stupid, Maryzora".
