Dueling Shows: with The Life and Times of Juniper Lee. Contary to popular belief, this show did not copy off of American Dragon. Both of their respective animation studios finished within a year of each other and neither creator knew of the other's project till they were pretty much on the airwaves. Ironically both shows lasted three seasons and were subject of Executive Meddling.
Originally, the plot with the Aztec skulls and Dark Dragon plots were supposed to be based in different seasons, the Aztec Skulls plot taking place in season 2, with the Huntsman plot in season 3, likely explaining the fact that the plots weren't given enough time to develop: There wasn't enough time to properly explain all the plot points because they weren't getting another season. Other ideas involved a possibly Darker and Edgier approach with the finale of the second season, involving Sun Park being thrown into a volcano, and also revealing that Jake's Grandma was Chang, both ideas were discarded for being "Too Jetix". Rose was also supposed to stay in New York, but Disney said it was "too confusing" and sent her to Hong Kong. A lot of these ideas would probably have helped the show in the long run.
Word of God: Steve Loter (Director) said that Rose would have came back to New York after "Hong Kong Longs" had the series continued and that Jake and her would be together.
