The realization of what would happen next settled gradually over Harry in the long minutes, like softly falling snow.I've got to go back, haven't I?That is up to you.I've got a choice?Oh yes. Dumbledore smiled at him. We are in King's Cross, you say? I think that if you decided not to go back, you would be able to…let's say…board a train.And where would it take me?On, said Dumbledore simply.
