What if when Tim went off to look for Batman when he was lost in time he bumped into Phantom.
They made a Deal
Phantom knowing CW helped him find Bruce and how to get him back safely, Phantom in return for reasons (hurt badly & recovering, or evolving in power) needed someone very ecto-contaminated (Ra's fault) like Tim, to be contained in.
From a magic user point of view, knowing very little of the GZ and how they work, Tim made a very powerful Deal with a powerful death being (High Ghost King Phantom: Hello!) and is now somehow pregnant (not really but they don't know that)
Danny while inside Tim inside his core can still hear the world outside normally and can share his emotions with Tim to communicate. Which looks a lot like Tim is speaking to his belly just like expecting parents do.
This could be angst or crack
or
my personal favourite, different genres for different pov's
Tim's would be happy, just regular getting his life back together being a total BAMF, coming of age type of vibe
The rest of the Batfam and other heroes pov would be angst, paranormal, psychological horror.
Misunderstandings galore
Dick regretting heavily his decisions which caused Tim to run away because he did not believe him and he has many Regrets.
Bruce feeling guilty that Tim felt the need to make such a decision as to make a Deal and end up pregnant just to bring him back.
Meanwhile the magic users have told the other heroes about Tim's situation and now think that he's going to give birth to the child of a very powerful death being and if something happens to Tim to risk the baby it would cause all of their worlds destruction.
so pretty much-
Tim-Girl Boss, Gatekeep, Gaslight
Batfam- Much Angst
Others- *panicked chicken noises*
