The Aerie scenario is a little weak but I've always gathered that the Master Wraith is putting a spell on everyone above and beyond the simple illusion, that makes them more compelling than they should seem. That's why you can't even TELL the lover that it's a fake unless you have high WIS (or is it INT? I forget, don't feel like looking at the moment)
Regardless of what you think of the scenario, I think it's acted very effectively.
And the Master Wraith encounter is one of the few redeeming aspects of the Jaheira-TOB romance. (Well, until you add her flirt pack, that is!)
