Yes, I went the good Shadowheart route, I rescued Nightsong. So at this point, where I am, Vlaakith already showed her mug. And Lae'Zel has been kidnapped. I'm really hesitant to have to start over, as I've done a lot in Act 3 already (completed several quests, including Shadowheart's). I'm at the point where I feel like I should just keep progressing and hoping for the best. It's good to know that just because I decided to respect Shadwoheart's wishes to not be too pried into early game didn't lock me out of some interesting scenes.
