Bitchcraft - S3-E1
Continuity mistake: The voodoo woman stabs herself in the hand, inflicting a mark and drawing blood on the woman across from her on her right hand. In the very next scene, after the voodoo woman gets up and leaves, the woman's damaged hand has no marks. (00:23:40)
Answer: Moira's ghost form is unique because of the way she was treated when she was alive. To people who do not sexualize her and truly understand and view her for who she really (namely women), she is seen as an older woman. To people who objectify and don't care to see the truth (namely men), they see the young seductive Moria. It's a strong directorial choice to eventually show how Ben Harmen comes to terms with the truth of the house and himself.
