Do any of y'all think he's not the mummer's dragon, though? Part of me hopes he's not just for the conflict it could cause when Dany finally gets to Westeros.
I'm hoping he's a real Targ as well for the same reason. I'll take the Blackfyre theory as well.
Lot's of people are because he came too late to the story or some shyt like that but I'd be disappointed if he's just some dumpster baby with Targ features that Varys found for his grand scheme.
