TO BE CONSIDERATE: The pdf I found was an unrevised draft version of the EEAAO script from December 2017 by Daniel Kwan and Daniel Scheinert. There's tons of reasons we have first drafts, second drafts, fifth drafts. It's to make the art the best it can be, and that shows in the film's final production.
In this version, we follow Jackie Chan and his wife Winona in a universe in which they're trying to do their taxes. Their adult, married daughter, Joy- has an alter ego (Jobu) from another universe that's trying to kill them. The relationship between father and daughter to me is extremely unexplored- considering that Jobu is the main antagonist (is she really?). The focus, especially at the end- is mainly on Jackie Chan and Winona's failing marriage, and how they're agreeing to try and make it work. This draft obviously lacked a lot of the charm and sincerity of the final film, but that's to be expected.
