First of all I want to begin by saying this new Bran is annoying AF. Did you see how annoying he was in episode 3 when he spoke to Sansa? He was talking like a Robot.
Anyway I dont think Jon or anyone will belive what Bran has to say. Since there is no proof to back up what Bran says.
So this is how I think the revelation will occur.
Some point in this season or maybe the next, Bran will warg into one of the 3 Dragons!
IMO I think he will take control of Rhagaer and proceed to set Jon on fire only for him to come out unharmed. This will shock everyone and his true parentage will come to light.
