I always kill Asterion and leave Gale doing the debit card scam from inside the ATM. I told Wyll I didn't him want him and so far I haven't seen him (I'm currently mooching around inside Moonrise Towers). Volo is in my camp even though I have never spoken to him. Halsin is there though I wish I could get rid of him. I wont be inviting Jaheira to camp. Oh, Barcus was in camp but he seems to have moved to the inn.
The whole Shadowheart/Shar/Selune thing seems to take up a lot of the game when none of it is really important to the main story (other than Thorm being a former Selune/Shar worshipper way, way, back when).
