Danny Phantom Universe

So the Universe of Danny Phantom, so what is going to start the effect?

Danny doesn't become a halfa?

Jack died in some incident before this?

Maddie finds out about Danny before anyone else?

Valerie finds out about Danny and is cool with it?

Danny makes an accidental wish?

Ember actually likes Danny?

Maybe Pamela Manson decides to seduce Danny to keep him from Sam?

Or who knows what else.
