Just Desserts

In many a story the Big Bad (or The Dragon (or maybe even the slightly annoying bad)) will get his payback for being a Bad. And the payback is that he gets to be dessert... Well maybe not dessert - sometimes it's an appetiser, sometimes a main course, once in a while, it really IS dessert. The high point of this is when the Bad is eaten by the primary character (Hannibal Lecter anyone?).

This does NOT include a Heroic Sacrifice. But may be subverted with a minor character being killed and eaten in obvious foreshadowing of what is going to happen to one of the bads at some point. While Mooks may be recipients of the Just Desserts, a true Just Dessert is reserved for those higher up the ladder.

Compare The Dog Bites Back, Devour the Dragon.
