Dany does her Florence Nightingale bit. I hope she doesn't catch any diseases. She thinks Targaryens don't get sick, which may even be true. This might not bode well for the rest of her men, though.
She meets with Reznak mo Reznak, who explains all the small print Dany didn't read when when agreed to marry Hizdahr. Weddings really aren't that great for the bride on GRRM's planet, are they? Luckily Hizdahr himself doesn't care for all the weird rituals; he just wants to get married ASAP. Apparently this will solve everything and there will be peace and tranquility throughout the land, including New Ghis and Yunkai.
So it's probably really bad timing for him when Daario turns up. He brings news that Astapor is defeated (we already knew that), and that some Westerosi have defected to Dany's side. Some of these will be Quentyn Martell and his friends. Apparently Brown Ben Plumm has defected the other way, although I'm a bit suspicious of Daario: I would not be surprised if he is telling lies to get Dany's favour.
Dany decides to finally sleep with Daario. This is probably a bad move. Is it more of a bad move than marrying Hizdahr? Not sure, though he eats dogs which can't be a good sign.
