I was thinking about the theory I've seen that Shadowheart was a Selunite brainwashed to go on a suicide mission for Shar, and how she mentions her memories will be returned to her in BG, but I might have understood it incorrectly. I was assuming she would have been a Selunite recently brainwashed to go on this mission but now I'm wondering if the mostly nice person we know from the EA is a result of all her memories as a Shar cultist being taken, leaving behind the person she was before being broken into Shar worship, a personality potentially many years old, many years of very unpleasant things.
This would set up the potential for a drastic character shift later in the story, we'll potentially be dealing with a very different person, possibly one more upfront with their alignment. I'm not sure how well this kind of twist could play out, especially with SH as a potential PC. I guess this was a bit more obvious to most people, and I don't know if the data-miners have weighed in.
I was thinking about this the other day too. Memory manipulation could make for some very interesting story beats.
It also made me think of this SNL skit but with Sharran commandos
