People do lack respect for Tyrion though. His father at one point had some modicum of respect for Tyrion, or otherwise he never would've given him the position of "hand ot the king". Tyrion's whoring around with women like Shae is what made Tywin reconsider his respect.
That doesn't refute anything though. We clearly see that Dorne has a decent fleet from the ending shot.
I recall them both taking a large amount of ships with them.
I'm confused at what you're saying here. He said that it was necessary to build ships specifically to get Dany. Euron doesn't have as many ships as you might think.
The show has moved off on it's own direction from the books, so who knows? I think Dany would win a confrontation though, considering she has 3 dragons and a large fleet. Dany already promised to win back the iron islands for Yara, so a marriage is less likely, and a battle is far more likely to happen if Euron is sufficiently as crazy as he is in the books.
Which is why it's a moot point.
