One important point in favor "SH is supposed to be percieved only as mono at least in Acts 1-2"
When players actually initiate poly/open relationship with Halsin and SH they have to have a conversation with Shadowheart that can be seen in this video (timestamp 1:57)
She says it's "Bold of you to ask" in responce to player suggesting it. I am no expert, but isn't it the type of conversation that is expected for open/poly people? What is so bold about it?
A) There is clear implication somewhere in Acts 1-2 that Shadowheart is not mono. B) It is bold to ask her about including someone else.
To me it seems that statements A and B can't be true at the same time.
