[Man of the North]

It is a toss up to the slaver and Robb.

The slavers should have been smart enough to know that Dany was going to due something. If I was in that position I would be careful.

But Robb made the biggest bone head mistake a king could due, when he married that sweet Westerling girl. Losing half his army in the process.

So Robb is the winner by a head, because he lost his for that mistake.
