Are you saying that you see the companions as sort of Schrödinger's companions, and that makes it impossible to analyze their characters? To a certain extent that may be true, but I think the companions do have enough characterization that it doen't feel like that for me. All decisions are impacted by circumstances. Tav encouraging something is an external factor, but, for example, so is Shar telling Shadowheart to kill. Other times, it does feel like the writing keeps things deliberately ambiguous, so players can headcanon what they want. Forgive me if I'm misunderstanding you.

Does it help to know that if Tav is dead and Shadowheart confronts Nightsong alone, she apparently always kills her?
