Just what the title says! In your opinion, regarding the story flow in act 3, what do you think would be the order of quests that makes the most sense? So far all I've really done is progress Gale's and Astarion's personal quests and investigate the murders a bit. I know there is still a ton to do, but I am concerned with what will happen if I do something in the order it might not be intended... House of Hope, the prison, Orin's victim, etc? Spoilers are fine, if needed. I've seen enough on here to get an idea of what outcomes are possible.

This is my 4th playthrough but I've never actually finished the game. I keep getting the feeling I missed something, and honestly I'm worried I'll be so disappointed with the ending scenes that I just go back and start a new character. /sigh But I am determined to finish the game this time.
