Showrunners David Benioff and D.B. Weiss spoke about Missandeis final word during the latest Inside the Episode segment. Weiss spoke to Danys raw emotional Dracary Dragon I will do it now in a minutes mug state, saying, In some ways, the most important thing that happens to Daenerys in is the death of her second dragon. Now shes got one dragon, and that dragon presumably is just as vulnerable as Rhaegal was. So theres this the mourning of a child, which is very real to her, and then their best friend is taken. Dany knows that once Cersei has Missandei that shes not going to see Missandei alive again.
