As quoted from a friend who doesn't want to be named "
it was in the datamine since launch, but since it was labelled as unreachable up until patch 5, people thought they had realized it wasn’t a good idea and were in the process of rewriting it, but turns out they decided to go through with it anyway for some reason. "
If you
reject bhaals legacy and power,
while it makes sense in the context of power to see a fresh outrage coming from a drow such as Minthara with her ambition revolving around power and if your approval of her is high enough the break up does not actually happen, supposedly if it falls (mine was 99 and did not move down not even by 1) down below 40 you get the option to persuade her into staying in relationship with you later on, but on the flipside of this writing it also feels just inconsistent as this is the only sure way for the dark urge to reach the epiloque with Minthara, I was under the impression that the dialogue would be slightly reworded to reflect the narration changes in respect of epiloque.
If this was planned and written with epiloque in mind, why not just keep it unreachable to a point where its ready for a proper release along with the consequences or is this just a way of testing the waters to see how playerbase reacts to it?
I actually enjoyed and loved seeing MInthara get heated up here but at the same time it felt a little inconsistent that seconds after so, she whispers in a soft tone "come to me" as we indulge in yet another passionate kissing scene,
maybe in a future update she will temporarily become independed and retreats back to camp sulking over the loss of power and we can reconsile with her? and if you already in a romantic relationship you can just pass the dice check on it.

Highlighted in red is what I feel would be the next best logical step to do, the same manner of treatment like Karlach received upon death of Gortah, retreating back to camp.. what's your thoughts on this?
(edit) I see this as an opportunity to have more dialogue content for Minthara with a possible romance scene played when reconsiling with MInthara, where this time around we would be doing the leading in an extensive manner to pamper her up with, this would fill in the gap for lack of a romantic scene for MInthara in Act 3 after all...
