In the fine tradition of soap operas and time-traveling sci-fi extravaganzas, Wicked features amnesia, jumps through time, gaps in time, and mysteries that only get cleared up years later. Melena and Elphaba are at the center of this action, which is fitting in a book that loves mirroring characters. Both mother and daughter experience memory loss, and their respective bouts with forgetfulness are, interestingly enough, linked to pregnancy. Themes of memory and remembering are also a major part of the cultural myths and legends that permeate the book, particularly the long-lived legends of the Kumbric Witch. In Wicked, memory has as much to do with remembering as it does with forgetting, and characters forget and remember (willingly or not) both good and bad things. Memory and the influence of the past often act in rather unexpected ways on characters.
