Jon's father was Dany's older brother so she is his Aunty. Given that I would say she is the one with most claim to the throne. I also think Jon won't want it. I predict in the final season that it will be the same set up as the beginning with the Starks being the head House of the North but recognising the Iron throne as the one ruler. I sadly think Jon and Dany will together fight the White Walkers, Jon will die and Sansa will take Winterfell.
Arya - the pie was brilliant I was cheering, it was so fitting.
I think Jamie will believe that Tommen killed himself but will blame her. Their son killed himself bc of what she did and who died. I don't believe Cersei will die at jamie's hands but I tip he will shift sides against her and be with tyrion.
And I'm also loving the strength of the female characters! Even Cersei. But now all her children are dead, the only ones and things she has ever really loved, she will go completely mad. She is a horrible woman but she adored her kids
