Not to mention the theory that Tyrion is the result of Aerys raping Joanna................

I thought the Aerys/Joanna thing was for Jaime and Cersei? And that Tyrion is truly Tywin's?

Mind you, Jamie and Cersei certainly fucked like Targaryens tended to do. :P

Jon wouldn't be a bastard if Rhaegar and Lyanna were married when he was conceived before Rhaegar rode off  to battle at the Trident. There's precedence for polygamy amongst the Targaryens. It's also been implied that Rhaegar wanted to somehow dethrone Aerys should he have returned alive from the Trident. So if three Kingsguard were at the Tower of Joy they would have to have been in on Rhaegar's plan and acting on the basis that Rhaegar was king and not Aerys when he died on the battlefield. Therefore they were guarding Jon as the rightful claimant to the throne with Aegon having been recently killed during the sack of King's Landing.

I enjoy the insinuation that Lyanna was with Rheagar by choice and willingly and that Robert and Ned just couldn't accept that.

Agreed, but I think it was more that Robert couldn't accept that, and Ned got dragged into it by the honor of protecting his sister, as well as revenge for Aerys killing Ned's brother and father.

I feel the Rhaegar/Lyanna theory has enough merit to be true, but I kinda wish Jon is just what he is - Ned Stark's bastard =P

I don't buy at all the Aerys/Joanna thing, but I'm fascinated by the depths fans will go to to find things to talk about while waiting for the next book.

Yeah, it's a lot more in-character for Robert than for Ned, but I can see it as part of why Ned was so determined to make Robert a better king than he was, and why he cared for Jon as deeply as he did.

Yeah, I'm like 99.9% sure Rheagar and Lyanna Stark were in love with each other and she ran off with him. Robert feeling slighted + Aerys being a shithead is what colored the perception of Rheagar taking her against her will.

If we continue with the Jon is Lyanna's child theory, then it's all but certain that Lyanna died giving birth to Jon as she was in a "bed of blood and flowers" and had a fever before she died. Plus the promise she made Ned swear.

I don't really buy any of the theories about the Lannister kids though.

Dumb crazy theory 1:  Jojen is really a magically de- or reverse-aged Howland Reed.

Dumb crazy theory 2:  Also Jojen got turned into paste and fed to Bran to give him his magic tree powers!

Bran eating Jojen paste seems legit though

Jaime's recounting of the events that made him the Kingslayer was well-acted.  And I had forgotten the details, so it was pretty epic to watch.  It's nice how this stuff comes back to me even though I've forgotten.  Like Daenerys taking the city.  I knew she did something like that and freed a bunch of slaves but I couldn't remember the details.
