So. No one knows. They never showed us what Ja Khem wrote to her. Unless they did and we missed it. I'm watching everything over again with subs so hopefully that'll shed some light. Not sure what milky way means in this context. Haha. I'll have to repeat Ep6 to see. Btw I thought the flying snakes towards the end was the randomest thing ever since they weren't even in a sacred place. Well who would've known??? Haaha.
