In WotFK: We see Ramsay Snow doing many things, like marrying Lady Hornwood, being Theon’s Reek and then putting Winterfell to the torch while also taking Theon as prisoner and in the meantime, betraying and destroying a decent Northern Army of 2k if I remember correctly and killing Winterfell’s own Castellan. I suppose, this all was a plan of Roose Bolton, after he allied himself with Tywin? But how did he communicate so efficiently, quickly and secretly with Ramsay? It appears so complicated.
