In case anyone was interested, came across these fascinating bits of fully-voiced datamined content that further enrich her character and add some necessary consistency;
Minthara actually reacting to her knockout recruitment
Halsin throwing an ultimatum about who stays with the group
The knockout reaction is actually pretty damn great as it adds proper consistency by her acknowledging being bonked on the head. 100% should already be in the game.
The ultimatum from Halsin on the other hand although is super interesting and gives further insight into Minthara as a person, ends up terribly clashing against Halsin's signature wisdom by making him act unreasonably stubborn and outright hypocritical considering he forgives Kagha (even ends up quoting her).
I wish Larian would stop cutting out entire scenes and plots, but revise them and put them back into the game. It makes perfect sense that Halsin would have an issue with Minthara, so just by making him act more reasonable along with an option to persuade him to stay would entirely save the scene and give some necessary development and consistency for both characters.
