Your right. Once again, I got the names mixed up. It was young Ned not Jamie. Refresh me please on the girl who gave birth. Was that Ned's sister? Was she married to a Targaryen or was Jon born a bastard? I do not remember that part of the story. I assumed after watching the re-run of the episode that she was a Targaryen and my remark was based on how beautiful both she and Khalesi were.
I know that you think that I somehow used some "aids" to get my predictions right and that is fine with me. You are completely entitled to your opinion on that. But no, I do not. The mistakes that I have made primarily are due to getting a few names wrong as in Mereen, Dorne, and now Jamie and not Ned. If I had proof read my post I would have caught it but normally I just type and send and if I get a name of a character wrong, then so be it. I knew that Bran followed Ned up those steps and not Jamie. It was just simpy getting a name wrong. Hell, someone chastised me for calling Walder Frey, Walter Frey. It really isn't very important to me making a slip like that. I am having fun on this thread speculating and commenting with you all.
Lyanna Stark, Ned's sister.... she was "kidnapped" by Rhaegar Targaryen and taken to the Tower of Joy.
Lyanna had been betrothed to Robert... when she was "kidnapped", and Ned's brother Brandon Stark went to King's Landing to demand her return and was imprisoned along with his friends who were sons of other Northern lords.
The Mad King demanded the fathers of those he imprisoned come to King's Landing to account for their sons' actions.
They all went to King's Landing and were murdered by the Mad King, Brandon strangled himself to death trying to get free to help his (and Ned's) father who was being cooked alive in his armor.
This drama spurred Ned to rally his banners behind John Arryn (The Vale) and Robert Baratheon (who rallied his banners) and begin Robert's Rebellion.
Once Robert's Rebellion was over, Ned took his friends to the Tower of Joy to retrieve Lyanna which is the scene you watched Bran observe in season 6 last year.
This is a key piece of backstory that hints at Jon Snow being Lyanna and Rhaegar's son, thus making him a Targaryean/Stark.... nephew to Dany and potential heir to the Iron Throne.
