- Considering Evil Jeannie had hundreds of past lovers in one episode, it is also possible that she was, well, naughty and as turned into a genie as punishment.
Celebrity Paradox applies to both I Dream of Jeannie and BewitchedEach is a television show in the other show's universe.
The Animated Adaptation Jeannie is another sister of live-action JeannieBoth are favorites of Great Hadji; both were given difficult apprentices to chaperone; both have a similar attitude about their 'masters'. Animated Jeannie was imprisoned while searching for her sister, and washed up in the California surf, found by Corey.
Jeannie was turned human as a babyAs a variant on the above WMG about why Jeannie mentioned growing up human but was then established to be from a family of genies, perhaps Jeannie's family were genies originally but she was made human as a baby either as a reward for her family's service (so she could live a free life) or the Djinn did it so she could grow up to be a proper wife to him rather than just a servant (given Djinn are immortal it's not unreasonable to think he may have planned a marriage a couple of decades in advance). Then when she refused to marry him she was turned back into a genie as punishment.
