You know how the observants are being depicted as these annoying rule-lawyers who think they know best for everything?
How about we flip that a bit?
The observants see how badly danny is doing being a hero, going to school, being the new ghost prince until he reaches the maturity to be the ghost king. It’s a lot, he tries to spend time with his friends as well even if he barely got 4 hours of sleep in the last few days.
So the observants decide to take care of it! It’s best for the realms if they have a competent ruler later on, so they stop ghosts from leaving the realms until school lets out.
No only one of you, you are allowed to team up, but no more than two at a time!
Every second weekend they don’t allow anyone through. Danny needs his socializing! They saw what happened if he is lonely!
Danny doesn’t know they are doing this, nobody tells him.
