sometimes our companions might be lead tav to a desperate situation eagerly, just because of their blindly follow.
however our tav should have the wisdom as Sherlock Holmes to survive from the live acting role playing game.
example -- rosymorn monastery, using the githyanki machine should reveal a dark secret that lead to Vlaakith.
if you can have the chance to do mind detection or talk to the dead with the medical officer,
tav should gain a dialog option with plenty reason to reject lae'zel's blindly follow -- the desperate situation leading.
