This question already has an answer here:
I'm watching season 7 and in the latest episode, Jon meets Daenerys. She tells him he can't be king in the north, as there is only one king. My question is, why is everyone saying that Yara will be the Queen of Iron Islands? She has special treatment from Daenerys or she is just ignorant?
EDIT: I rewatched the episode where Yara first meets with Dany, and they say they want the Iron Islands back. Dany seems to accept. That means she will let her be queen of her islands? If so, why she treats her specially?
