The author could get away with anything if you use "characters evolve" as an excuse. I mean what if SH stated acting and talking like Karlach for no reason? Oh I guess she's just evolved lol Make it make sense dude.
It's a discussion that always leads to the worst take you've ever seen once it goes on long enough. Yes, authors *should* invest in consistency and moderated suspension of disbelief. It's their greatest asset. At the same time, you will always find someone who thinks character x couldn't possibly do y because they hate it personally. Always. Without fail. Sometimes the transition is that horrible and it makes no sense. Sometimes it was Tuesday as usual. What should be criticized is the transition and everything that made it unbelievable.

He could similarly take Karlach, fumble why Wyll chooses to believe her, and have people declare "OOC". Was it OOC? Or just the hypothetical set up? That's the issue with potentials. Everyone, and I really mean everyone minus two people ever in this thread, agree the transitions are botched. Completely, utterly, somewhere. We've also covered the ground "personal attacks against the author are not productive", "complaints that the author did this because he hates me personally" is not conductive, and "let's not accuse real people of fetishes". There is nothing controversial about disliking every other thing about Halsin. What people choose to be actively bothered by is their choice.
