Here's why:
* The series is still in its early stages: The Percy Jackson and the Olympians series on Disney+ is only just starting, and there's no official confirmation on how many movies there will be.
* Character arcs and storylines: It's possible that Annabeth Chase's role in future movies could change depending on the story being adapted.
* Actors' schedules and availability: Alexandra Daddario is a busy actress, and her availability could impact her participation in future movies.
While she's reprising her role as Annabeth Chase in the Disney+ series, it's best to wait for official announcements regarding the future of the franchise.
