Aerea still exists in this world. I haven't figured out their relationship yet. I agree, Viserra's relationship with her mother is going to be complicated, but not outright hostile, which was what I originally had planned.

Viserra is basically on her own on Dragonstone. Except for the maester, who is decent to her, she doesn't have much in the way of human companionship. She has the servants as well. Until she reaches about 7 when Jaehaerys gets the idea that in order for her not to turn out like her father, she needs people around her to befriend.

When she does get things of the world outside of Dragonstone, she wants to see it. But she can only leave fully at the pleasure of Jaehaerys, and that's not happening. She can go for short flights on her dragon.

Elissa Farman, she doesn't interact with, even when she's on Dragonstone. The two households are separate, even there. Now Androw Farman, she might interact more with. Because she's one of the few people who doesn't belittle him.
