You'll be able to ask her about most of that. Later. And if you read the documents in Moonrise Tower, you can also figure it out on your own. The Shar temple remains a mystery though. And if Shadowheart didn't actually become a Dark Justiciar she shouldn't be wearing the gear.
Why later? That's the issue. I was in the inn. We were discussing going there. Who in their right mind will not mention that the enemy is their dad? There is no excuse their.
Yes I find some documents but it doesn't excuse the writing for that path. If she was dead I will understand. She is right... There... ??
SH was already outed as a Shar cleric in my party at that point. Can't Isobel sense she can go in the shadow cursed land without her blessing?
