I think Tip/Princess Ozma will be in Part 2 due to a character I just realized was mentioned in part 1 initial scene. The professor (I don't know his name) mentioned Professor Mombi, head of the Biology department.
It's definitely not just a random name, especially how inform the cast- Ariana, for example- and directors are of Oz lore.
Hopefully, it will further concrete that part 3 will happen. That, and hopefully, she and Dorothy will meet in the end.
