For you Game of Thrones fans, see this youtube video from GoT Academy for background discussion of the meaning behind what Dany does here. As fantasy fans know, it’s about more than the fantasy.
For you non Game of Thrones fans, a quick recap:
Danaerys started the series as a exiled princess, sold into marriage by her brother to a barbarous Khal Drogo, a leader of the Dothraki horse people. Turns out the Khal was enlightened as sexist Dothraki assholes go so she learned to rule as a Khaleesi, which is something like a Dothraki queen. But Khal Drogo died prematurely and instead of going off to the Dosh Khaleen, sort of a retirement home for ex-Khaleesi’s, Dany decides to hatch some dragons, free some slaves and, in general, become something of a badass.
Anyway, by a turn of fate, she ends up in the hands of the Dothraki again, who take her prisoner, walk her to their city in the sea of grass, and are determined to lock her up with the other widows. But first, the Khals have to decide if she’s even good enough to be locked away for life. Or do they have other plans for her.
We’ll see about that…
