Extremely disappointed about something about act 3.

I about Argenta like OK Argenta acted like a brain-dead idiot but she is a sister of battle so I excepted that from her, what disappoint me is that everyone reaction was “yea whatever lmao” except from Idira and my only option are telling her to fuck off or “yea whatever lmao” not  “You will be punish for this once we leave this place ” or  attack her without killing her a punishment , tell her that I can’t trust her I animor,  ect.  

Even Jae confession has more integration that this, and that is about the past of a character you can totally ignore if you want. 

I was expecting more about something that was supposed to be an important part of the plot.
