re: Crackpot ASOIAF Theories SPOILERS

Never thought about the HotU vision in that context. When I read ACOK, I always assumed it was Elia and Aegon, and Rhaegar basically alluding to how he needs another child but Elia can't have any more children, which brings Jon into being the PtwP and HotD.

But Rhaegar died before Lyanna did, and never got to meet Jon.

My question is, what happens if Lyanna lived? Would Ned have protected her by sending her and baby Jon to Essos, similar to Aegon? I can't imagine that Ned would let Robert kill his nephew and Lyanna.

And if Elia and her 2 kids as well as Rhaella lived, would Elia, Rhaenys, Aegon, Rhaella, Viserys, Dany, Lyanna, & Jon live in some sort of Targaryen stronghold elsewhere?

Also, would Robert still have wanted Lyanna if he knew she had a baby with Rhaegar? Something tells me 'hell no.' This opens up a huge can of worms. Now I see why Lyanna had to die in labor. Easier for GRRM to write and set up his story .
