After Barristans coup, nobody gets sent to the dothraki sea to inform Daenerys. Her khalasar leaves right after her, leaving only the maimed and old behind. They wont tell Dany anything she doesn’t know about the events of Meereen. After the battle at Meereen, some ships from the Volantene fleet (which are three hundred, some will escape) will first stop at new ghis with the news, and the information will then sail to Qarth and Volantis. Who will go to Dany to inform her of anything?
