Galazza Galare the Ghiscari thinks Dany should marry Hizdahr zo Loraq so that there's a king and somehow that will make her more powerful. She agrees to have a chat with him about it. She doesn't fancy him, but she does set him the challenge of keeping peace in the city for 90 days. If he succeeds, then she'll marry him.
Ser Barriston doesn't approve. He thinks they should abandon this place and head to Westeros and conquer it. There is talk of marrying without love. Apparently Dany's parents got marries because a witch called Jenny of Oldstones said they would beget a "prince who was promised". Is she the same old woman that Arya met on top of a hill with Lord Beric and who got freaked out because Arya had an aura of death about her? That would have been before the red wedding.
Anyway, then Dany's true love Daario turns up and she considers having some fun with him but thinks better of it when he suggest she pull a red wedding stunt of her own to kill all her probable enemies. She's not up for that at all.
