I thought she was trying to get the Dragon to burn her so that her baby could come out, since real Targaryens can't be killed by fire. Word to Daenerys'.The discussion was about knowing whether or not the c-section happened (it very clearly did not happen)
As far her extremely short characterization, I agree with that, I just accepted that she wasn't supposed to be around for long
Folks getting aggy because the actors are Black, forgetting that these events happen to White characters in the book, so don't get too attached
