This article will guide you on what will happen when Shadowheart catches you sleeping with Mizora. Make sure Mizora remained alive during our run for the Baldur’s Gate 3 Mizora romance. This is due to the fact that the choice for the love scene is only available during Act 3. Furthermore, because Mizora is not a companion, there is no indication of an approval method.
Shadowheart will be satisfied with the outcome. She will say that’s how she was raised. The way she is trained…well, getting to know each other was positively encouraged. She will also tell you not to forget about her.
This might have been influenced by having high approval with her, or by a secret flag that varies each character. This might be similar to the Halsin relationship in the sense that they’re both fine with “sharing” your character.
