If one dragon was enough to take out the entire fleet and all the giant crossbows in the entire city.... why didnt she just do that last time and kill Euron to begin with?
And what was the point of Euron's character? He magically showed up, built some boats, shot a few arrows, and died. They could have easily gotten by in the story without him at all. All they had to do was say that the golden company also supplied the ships and put another character on one of the ships to shoot the dragon.
hold up, why did he have to fight Jaime?
Varys got executed for simply telling Jon that he'd be a good king. she might as well have just killed everyone who already knew the secret. also, it's a little dumb of the spymaster to be sticking around when he no longer supports her (and Tyrion already knows his stance). And even dumber to be trying to stir shit up right before the battle against Cersei. What the hell would have happened if Jon said he wanted the throne... not like he'd win against Dany or Cersei by himself. This issue would make way more sense to leave until after the battle.
Did Dany's army get a new supply of Dothraki and Unsullied? It was decimated after Winterfell and Euron's surprise.
