Hmm. Shadowheart did stay in my party about 90% of the time throughout Acts 1 and 2. I felt like I was paying attention, engaging her in conversation within her boundaries and taking note of how she reacted to things. I saw the majority of the story and character elements mentioned in the comments above with the exception of romancing her and
None of those conversations or in world reaction was enough to convince me that she was capable of making the 'good' move here.
Furthermore, the dialog flow itself is bizarre.
In my playthrough, seemingly anything other than just keeping silent -- which is an absurd prospect for my character given the stakes -- eventually results in her going mad dog and threatening to kill me, her supposedly closest confidant. As a test, I just remained silent, and Shadowheart -- the person who has been audibly whipping herself in a fervor for the entirety of the Gauntlet of Shar expedition -- spontaneously decides to quit her mission.
I see that clearly some people really liked it, which is great for them -- but for me, this pivotal moment just doesn't work as presented.
