The Wight

Fine!, got me there... But Stannis? Seriously? Or Ramsey? No skin in the letter? No body part? Heads on spikes??? Ramsey? Since when???

I'm pretty sure the pink letter was sent by Mance, There are just too many things to just let slide. Who from the 7 kingdoms has ever called the Night's Watch 'crows'? That's just 1 small reason. If for som reason it isn't Mance, I would say it was Ramsey. But Stannis?????? No.
