The Blues are now confirmed and the reason why I said that Hal, Terence Bubbles, and Stella are not going to be in the movie is that this movie is a prologue and Red, Chuck, Bomb, The Blues and Matilda haven't met Hal, Terence, Bubbles, and Stella back then and the reason why I said that Willow is not going to be in the movie is that the movie takes place in Piggy Island (called Bird Island back then), not Golden Island, and these two islands are different. Willow is born in Golden Island.
