I just noticed that the little brain devourer companion urges you to leave Shadowheart in the pod, to not even try to release her. Although it doesnt mind Laezel at all, strangely. Its a bit intentionally oblique and looks as if its just urging you to go on get to the helm, easy to miss on the first playthrough, but its noticeable on the second run when you already know some bits. And her pod is additionally hardened against tempering or opening, plus of course she reveals she is missing memories and her artifact was the reason Gith attacked. Quite probably a tragic role of the game, with options.
