IN Screentime Wise….
It’s safe to say that Elsa will take Zelena’s amount of screentime this year, which will be a lot.
As for the Knave….if Adam and Eddy are going to go with the Robin Hood Legend, and stick with the original story of Will Scarlett being Robin’s half brother on their father’s side….then I’m sure Robin will get lot of screen time with his half brother.
It’s without a doubt that Regina, Snow, David, Emma, Rumple, and Hook will get their normal loads of screen time, as for Belle and Henry…I think there’s will stay the same.
So in all….the screen time will stay the same, the only addition really being Will’s character sharing screen with Robin, Regina, possibly Hook and David.
