That craster's keep battle scene was possibly the stupidest scene ever to appear in the series.
So first of all, the Bolton guy scouts out the location. Ok. So he finds the captives and... leaves? Why? Why didn't he go in there, tell them: "I'm with your brother and will free you, but I will have to sneak you out one by one." He carries Bran out of the tent and slits his throat, problem solved. Later he can then kill Jon Snow during the assault or at some other time. But ok, he leaves them there. So in order to keep Jon and the others from getting close to their prison, he tells them there are dogs in there that would give them away.
This would imply that they plan to sneak up on the traitors. But they don't. They just run in there with their swords drawn. Who cares about the dogs?
So then the battle commences and the Bolton guy sneaks of to the prisoners. Why did he carry Bran into the woods like an idiot? He leaves behind the wonder twins, who would surely point out to Jon: "That's the guy who went off with your brother, he is a traitor." He should have just stabbed them all there and then. "Sorry Jon, when we attacked LIKE FUCKING IDIOTS these assholes killed the hostages we never knew they had. Oh that is your brother? How unfortunate. If you need a shoulder to cry on, go into the woods with me alone."
But no, instead of doing all these very reasonable things, he carries Bran into the forest and gets his neck snapped.
Just incredibly stupid.
