You make some good points, however there's still a lot of confusion here. When SH says "I was taught to reject anything that doesn't revolve around Shar" I took that literally, with both casual sex and relationships. Why would Shar even allow casual sex when it could likely lead to more serious attachments, potentially causing them to stray from her or lose sight of their mission? I could imagine her followers sneaking around sometimes in secret though, but being fearful of being caught. Not because Shar (using Viconia) would kill them, but with mental torture, manipulation tactics, mind erasing or even just simply the humiliation of losing focus on Shar.
When you say "she understands your indulgence because she was trained to do the same" are you suggesting she was literally trained to have casual sex? Why would she be trained to do that, like for what purpose? To seduce selunites or something?
And I've never done the Shar SH path. But from what Ive read about it and seen on YT, I thought it was implied that Shar gave SH a bit of a pass as reward for her devotion. So that's why the player can still sort of be with her minimally at end. Had she not been given that pass, she wouldn't be allowed even a casual relationship with the player.
I could totally be wrong here, but this is how I interpreted the sharran stuff.
As for different versions of the character, that works for anything from the present (start of the game) onwards. Her back story should logically stay the same. We only learn of this casual sex training thing if we specifically cheat on her with Mizora, which is optional and not tied to SH's main story. So if they really wanted this to be part of her canon back story, why not add it in somewhere to her main story? Otherwise it gives the impression that it's specifically added in as a way to wave off cheating and encourage casual sex. But nowhere in her main story is this stuff even remotely suggested...
I cant imagine her screaming or something at MC for that, personally im fine with her reaction. She seems pissed off but accepts. That being said, some disapproval certanly wouldn't hurt in that dialogue(Sometimes disappointment speaks much louder than hysteria or other words).
