Robb willed the Crown to Jon in the event of his death
You don't know this to be true! This has not been confirmed! I am a stickler for details! There will be no conjectural conclusions from unsubstantiated rumors on my watch... unless I personally make them... then it's okay.
The following bears the official Boaz stamp of nonsensical approval.
In ACOK, during the second or third Bran chapter, Meera and Jojen come to a great feast at Winterfell. They swear their allegiance to House Stark with the following words.
"To Winterfell we pledge the faith of Greywater," they said together. "Hearth and heart and harvest we yield up to you, my lord. Our swords and spears and arrows are yours to command. Grant mercy to our weak, help to our helpless, and justice to all, and we shall never fail you."
"I swear it by earth and water," said the boy in green.
"I swear it by bronze and iron," his sister said.
"We swear it by ice and fire," they finished together.
Bran groped for words. Was he supposed to swear something back to them? Their oath was not one he had been taught.
Meera and Jojen sound like the Wonder Twins. "Form of a gorilla!" "Shape of a giant icicle!" I think the above passage proves that the title ASOIAF is all about the Reed kids. There will be three heads of the dragon... Bran, Meera, and Jojen. They swore it by
ice and fire!
Seriously, I read this today and I was floored. I thought about starting a new thread... but since this is the current Jon thread I thought I'd post here.
Howland Reed's children swore by ice and fire. Why? Everyone thinks the Crannogmen are weird so they don't take notice of the oath. But Bran's thought regarding the vow was
Their oath was not one he had been taught. Bran had never heard this oath... this means he had heard and been taught the oaths of other houses, like the Boltons, the Karstarks, the Umbers, etc. Ser Roderick and Maester Luwin are shown to be highly conscientious and thorough in counseling and educating Bran, yet they somehow overlooked this one thing. Maester Luwin admits that he "
had not thought to see them" in Winterfell. But I got the feeling from the chapter that neither Luwin nor Roderick were not prepared for the Reeds nor their oath.
I think Howland directed his children to speak in unison (this way neither would forget the words on the long journey to Winterfell)
We swear it by ice and fire as a secret message. From later ACOK and ASOS chapters it is clear that Howland Reed told his children many tales of his younger days, especially his adventures among the Starks. Howland knew whatever secret Eddard kept for Lyanna... of course I assume the secret is 1) that Jon is Lyanna's son by Rhaegar and 2) that Rhaegar and Lyanna were legally married before Jon was born and 3) that Lyanna and Rhaegar believed in their hearts that Jon was the culmination of Ice and Fire, i.e. the Prince that was promised (TPTWP) aka Azor Ahai reborn.
I assume that Howland knew of Ned's death when he sent his children off to Winterfell. I think that upon hearing of Ned's death (Ned's dead, baby. Ned's dead.), Howland knew that he needed to get in touch with Ned's contingency plan for Jon. The words
We swear it by ice and fire might be the activating password that the Reeds are in on Ned's plan. Mayhaps Ned left instructions for an agent to open an sealed paper or do a specific action upon hearing the password.
I'm stringing this out trying to explain my thinking and to get you to buy into the idea... here it is.
We swear it by ice and fire lets Maester Luwin know that Howland is the executor of Ned's secret plan. Luwin opens a sealed note that Ned left for him at Lyanna's tomb. The note tells Luwin to send word to Benjen to talk to Jon. Benjen knows Ned's secret, but Benjen is missing and presumed dead. So Luwin is in a quandary about what to do... So Luwin sends a message to Aemon to tell Benjen to enact Ned's plan. Aemon does not know the secret so he leaves a message with Jon to give to Benjen. This means Jon holds an unknowable message about himself that only Benjen (or Howland) can reveal.
This is all complete, total, and unsubstantiated speculation based on...
"We swear it by ice and fire," they finished together.
Bran groped for words. Was he supposed to swear something back to them? Their oath was not one he had been taught.
Why did Meera and Jojen swear by ice and fire? They also swore by earth and water, bronze and iron. I'd expect to find earth and water in abundance around Greywater Watch. So the Reeds swore by their characteristics of their homeland. Remember Robb's crown was made of bronze and iron, i.e. the metals of the North and of Winter. The Reeds swore by the characteristics of the Stark's homeland. Ice and Fire are the components of TPTWP. The Reeds swore by Jon, i.e. their hope.
