Ser Jorah Mormont is hereby summoned to
maester to return from his scouting voyage and bring his queen proof of the Northern threat. He's also the last person living who knew Daenerys before she cut her teeth on slavers and offending armies, and she desperately needs his link to her old hopes and humanity in the days to come.
Missandei is also sorely wanted to fill the BFF role. Dany is currently in King's Landing, surrounded by people who either fear, dislike, or want to manipulate her ... and will soon head North, where people will similarly fear or dislike her. She needs a confidante who believes in her, who can draw a laugh out of her.
I've kept a lot of Daenerys' book canon but with show alterations, so show versions are welcome! PM me or comment here for deets, if you're curious. We all want to see Iain Glen and Nathalie Emmanuel's beautiful faces on our FPs; it is known.
