For those of you playing the home game, yes, Jareth did just play up the canon of the movie ending.
For those of you who haven't seen Inception; Jareth fixed it, but he fixed it too well and it backfired. Like life. Saito is richer than Bill Gates.
Jareth, and Sarah belong to Henson, Lucas, Bowie and Connelly. Saito, Cobb, and Cobb's children belong to Nolan, Watanabe, DiCaprio, and their parents. Probably.
