Woody's return in Toy Story 5 has sparked many theories, but there's one that, although possible, I'm not sure if it would actually work.
Following the ending of Toy Story 3, it would be difficult for Andy to return in a sequel film, but one specific story could bring him back.
As the movie that started the franchise, "Toy Story" introduces us to Woody (Tom Hanks), a pull-string rag doll who feels threatened by his owner Andy's newest toy, Buzz Lightyear (Tim Allen).
