I think kicking her out will stop the harper plot. It's part of the romance and she probably doesn't appreciate being kicked to the curb for some stupid old arrogant cleric. Use shadowkeeper to check the romance variable. If it's a 1 then everythings sweet and the romance will carry on, if it's a 3 then you've driven her away and you can't see the rest of the plot. It is worth doing by the way. I'm doing things opposite to you. In my other games I've always romanced jahiera but this time I'm going with Viconia.
