Jon Snow and Daenerys Targaryen have reached that awkward phase in their twenties when older people gently ask whether they’re planning on starting a family anytime soon. Especially after that boat ride , when they crossed the official threshold into " more than casual" territory.

But since Daenerys has aspirations of being a queen, she can't swat away questions of succession as easily as I can.
