Chosen answer: One: Zack doesn't meet Maya until after the movie. Two: There are 2 possibilities. The first one, the steps might worn off after they got to the ship. and the second answer, London said she talks to animals since she ate them, it never worn off.
Zack definitely met Maya before the movie takes place, SPOILER in the final episode when they break up Zack says they've been together for 3 months, and not only does the movie take place during spring break which is less than 3 months from normal graduation, but also their graduation date gets moved up since the ship got sold.
The movie is set between the last two episodes; they had already met.
