Looks like she takes Yunkai in ep 9 and decides to stay in episode 10.
Why are people so insistent that Yunkai replaces
Meereen? We still need a precedent to dismiss Jorah and the Mhysa scene has not occurred yet, which we know is her freeing the slaves in Yunkai, not taking the city. "Dany waits to see if she is a conqueror or liberator" - she is very clearly going to be a liberator. The conquest of Meereen occurs after the Red Wedding in the book. Besides, if she stays in Yunkai now, that means we will possibly have to deal with 3 seasons of her ruling the city, which would be awful.
