In the "Rains of Castamere" promo, above, the Wildlings plan an attack on a Night's Watch area that Jon doesn't think is worth Tormund's time. Meanwhile Robb and Catelyn also seem to be planning an attack, and Catelyn forebodingly says, "Show them how it feels to lose what they love." It's unclear who exactly the "them" is in that situation, but it's obviously someone the Starks aren't very happy with. Also, if you look closely enough, you can see a brief snippet of Edmure Tully at his wedding.
