- Family-Unfriendly Aesop: "Honesty isn't always the best policy"
- Moral Event Horizon: The witch is, initially, not clearly implicated to be evil. In fact, quite the contrary: When Melissa first tells you about her, the legend says only that she was reknown for CURING diseases and granting longivity—benevolent uses of magic. The more you see of her house, however, the more you realize that she was definitely some kind of crazy, paranoid, and evil, but the real kicker is if you find the "Antagonist Protagonist" ending. You get to see just how bad she can really be when fully unleashed.
