Let's talk about the "other mother." And yes, that's a reference to Coraline. If you haven't seen the movie, you should, it's one of my favorites. Spoiler alert! Coraline is a child who moves into the Pink Palace and is stalked by an evil monster who likes to kill children. The evil monster pretends to be Coraline's "other mother" and lures her in by treating her with love and gives her amazing gifts. In the beginning, Other Mother is a delight to be around: giving, caring, and attentive. As time goes on, Coraline stops cooperating, and Other Mother turns into Coraline's worst nightmare. I would say "Other Mother" or the "Beldam" as the ghost children call her, is the mother of polar opposites.
