Robin has been tricked into declaring war on the King. The Vale is now in open rebellion. Will be interesting to see if Jamie runs back to Cersie are attacks the Vale.
I agree with the comment made that Jon is making Sansa look smart by out retarding her.
My bet is on Melisandre dying next episode because that seems the only reason Davos joined up with Jon was to create that confrontation between the two over Shireens death.
They're not in rebellion. It's handled differently in the book, but LF has the Vale legally and with Cersei's consent. He also, by telling Cersei that the Boltons had Sansa and were hiding her, has the crown's consent to overthrow the Boltons.
Currently, everything LF is doing aligns mostly with what he is doing in the book. (Except in the dumbest, most retarded way.) IE, using Sansa but with Cersei's backing. I also think it's unlikely that Sansa goes back to Cersei. For a variety of reasons. She's now a woman and Cersei no longer has control over her and has nothing to offer her. If they think Tyrion is still alive, she's still technically married to him - LF could probably fairly easily convince Cersei it's best for the Lannisters and the crown if Sansa stays in the north to consolidate her power. (Winterfell could be considered a Lannister holding, since Sansa married into them. Ramsay's marriage is not binding as she had already been married.)
Rickon was stupid. He should have run zig zagging so Ramsay couldn't gauge how to lead him with arrows. What's the deal with Winterfell? One little bitty door that Wun Wun could knock down in 2 minutes. I thought these castles were prepared to repel sieges. At least riverrun had a moat and a draw bridge to make it harder to access. How long did Ramsay think he could hole up in that impenetrable fortress called Winterfell?
Winterfell was one of the more stable castles in Westeros - one of the biggest also. Remember though, both book and show had the Boltons completely destroy/burn the entire castle. They had to rebuild the ceiling just to marry Jayne in the books. The door probably should have been stronger, but not too crazy to think it was because the castle was still weak after being razed.
Sansa obviously promised littlefinger something for his help, the preview from next week made it seem like he wanted to "collect" on what was owed. whether that's marriage, winterfell, whatever. This is probably why she was hoping the Vale wouldn't need to intervene so she wouldn't have to make good on the bet?
or I could be off base and misreading things.
I don't think she promised him anything; him helping her is to make sure she is safe and under his protection. (IE that he has control over her.) But there's also a bit in that he actually was a total retard with Ramsay, and he'll need to make that up to her.
I think the "You know what I want" thing has nothing to do with a form of payment he needs, but rather, more to do with why he is doing any of this in the first place. At this point, we either assume (or rather Cersei could) that Tyrion is still alive, and thus Ramsay's marriage isn't legal. She can have ties to Winterfell. Or, we assume Tyrion dead/marriage is dissolved, and Ramsay is dead, freeing Sansa to marry again. It wouldn't surprise me if next episode LF becomes Harry the Heir. He marries Sansa, and through marriage, has ties to Winterfell and the Vale, with the main difference than nothing needs to be hidden. Cersei is getting totally hoodwinked, but as she thinks LF is her loyal friend, all she'll see is that a retainer has given her two major houses.
Everyone would get what they want, with the possibility of Sansa who will just get screwed like always.
