Well, she isn't the daughter of Aerys, Rhaegar and Rhageo - she's the daughter of _death_. Just as she isn't (necessarily) the bride of Drogo, Euron and Jon Snow, but the bride of _fire_. It's quite possible that the prophecy uses terms like "daughter" and "bride" as synecdoches, for "kinship" and "alliance" respectively. Dany might have come to love Drogo, but that's not what she married him for. Don't forget the "fire" part of the sentence. Yes, it may stand for passion - but for Dany, fire is, most of all, power. That's what these "marriages" are about. Maybe Hizdar is missing from that list, because that alliance was more of a dud, and ultimately failed to provide Dany with additional power.

My theory is that Euron might still have an ace up his sleeve (*cough* krakens *cough*) , that he hasn't shown Vici, but might well have shown the other captains. That might have awed them into submission.

For what it's worth, I've been saying the same thing for a while now. Would be really surprised if Euron didn't have Vics lost ships.

My favourite candidate for LF's fatal lamb would be Sweet-Robin. He's mother was certainly rather sheepish. And right now he's about to be led to slaughter, isn't he? Lamb has the ring of something sacrifical and Robin is quite probably supposed to be sacrificed to promote LF's agenda. If he ever discovered sufficient ferocity within himself to face down LF, he would certainly still be rather untrained. (Strictly speaking, "untrained" would disqualify people like Arya and Pod as candidates).
