a post action or event reacting by a single or multiple character, usually occuring in the next or subsequent chapter from the action. This is one of the key ingredients for testing an author's mettle. Any event not worth sequeling, should probably be jettisoned from the work. Sequeling develop characters and also underscores an events significance in the reader's mind, as well as summarizing what just happened by eliminating the less important details allowing the event to gel into a particular shape for future reference. A sequel is not a second book or film in a series, a misnomer for a follow-up piece.
