Personally, I think that bigger thing for Jon is to turn the cloak and then get back again. They already scraped the thing of Jon letting Ygritte go, which spoke volumes of his character. There's no need or use for him getting back to Qhorin to tell him: "She escaped me and we got lost." They are really fond of making Jon appear as a halfwit idiot, in the retrospect...
"D'you wanna lead? THEN LEARN TO FOLLOW!"
"I hope you make a better ranger than you did a steward." ugh
He will be with Mance for a while, so I think that the influence that Qhorin had on Snow will get dispersed between Mance, Ygritte and perhaps Magnar (if he makes the screen).
We'll see how it works out with the Dragons. I honestly don't think that Pyat would have a motive and certainly less of one than all those greedy citizens of Qarth.
Yes, I'm afraid of that as well. Tywin or Gregor Clegane, both so wrong.
Well, Robb is halfway in the West, having won at Oxcross. Tywin will march on King's Landing - they don't have the time to have him march on the Riverrun raids and then back, in my opinion. Robb will receive the word about Bran and Rickon and he will turn to march on the North. At the Twins he will stop to honor the Freys with the wedding to let him pass, even though he will not be marrying a Frey. No bedding, but Red Wedding still happens. If it's too quick, they will have him stop at Harrenhal, since it's already a set built - saving money. I won't miss Edmure, though I will
