The major point of the episode that was left out of your synopsis bears noting. Bran, now the Three Eyed Raven, goes back to the Tower of Joy where a young Eddard Stark finds his sister Lyanna close to death.
She whispers something to him that the audience doesn’t hear, and then “Robert would kill him”. Ned is handed a bundled baby as his sister begs him to protect and raise the infant. The camera does a tight shot of the infant’s face and then opens up on the face of...JON SNOW! Ba Da BOOM! Does Jon trace his Stark bloodline to the maternal side, leaving the obvious conclusion that none other than Rhaegar Targaryen is the babe’s father? Can we say, Aunt Dany? Why, yes, we can!
Poor Cersei, you better enjoy sitting on that uncomfortable chair while you can.
I blew that part big time in my synopsis. Thank you for the addition.
