I understand this a lot better, thanks. I still don't necessarily agree cuz people change their minds all the time. It's definitely a problem for Lae'Zel, because as you say what isn't there isn't there and she IS quite fierce about her boundaries. But likewise what is there IS there for Shadowheart, and it's just Halsin's causing most of the problems other than the usual fan quibbling we're all doing wanting the rest of the writing to be more ideal in some way.
People do change their minds all the time. But this is a video game. Random 180 changes to characters should be explained. If she would no longer be interested in mono after she was written to want it in act 2, then that needs to be implied. Add conversations with her about it, where she shows displeasure with the way things are in the relationship, and that she'd rather have it be an open one.
Now don't get me wrong, nobody actually wants this, but at least it'd remove the inconsistency from it.
