199% Suprise, not a single way of foreshadowing this, except Catelyn

cry: ) saying Walder Frey is a dangerous man last season, and Roose Bolton making deals with Lannisters with the release of Lannister, but seriously saw no single inkling of them having the balls do to THIS. Extreme wtf.
Been getting melancholic text msgs from friends since last night to just watch the episode (a day later then they did), now I know why...
Needless to say fully rooting on Stannis and Daenyrys to come fuck shit up from now on...
