Jareth the Blue
Summary: Sarah leaves the Underground after her triumph over the labyrinth. Jareth becomes depressed. Bluebeard arrives masquerading as a travelling Lord, steals Jareth's pendant while he sleeps and takes over, locking Jareth in the castle tower and stealing his powers. Bluebeard kills off Sarah's parents in a car accident and comes to Sarah to console her, using the pendants powers to pretend to be Jareth with blue hair and brings Sarah and Toby back to the Underground to woo her into marriage. Bluebeard banishes Sarah's friends without her knowledge when they try to help her. Sarah is reluctant at first because Toby suddenly doesn't like this new blue haired Jareth & he isn't really the same as before, but agrees to an engagement after a funny tasting nightcap... In a state of hallucination, the marriage breezes past Sarah's oblivious being.
Bluebeard leaves straight after the wedding, called by a wisher in the Aboveground (he inherited Jareth's responsibilities as well) and leaves Sarah the keys to the castle, telling her she mustn't go near the tower. She gets curious and opens the forbidden tower. The real Jareth is disbelieving and overjoyed to see his beloved again. Bluebeard comes back and in a fit of anger, attacks Sarah. Can she trick the pendant and its powers away from him or will the Lady of the Labyrinth become another of Bluebeard's deceased wives?
