Season 2 and 3

I really hope that next season is just The Hollow Boy. It either has to be season 2 is just The Hollow Boy and season 3 is The Creeping Shadow and The Empty Grave. Or season 2 is spilt into 2 parts and part 1 is The Hollow Boy and 2 is The Creeping Shadow and then season 3 is just The Empty Grave. The ending of The Hollow Boy doesn’t really have an impact on the characters and the story unless there is a break between books 3 and 4
