Game Of Thrones: 5 Fan Theories Confirmed By Season 6 (And 5 That Were Bullsh*t)
4. The Umbers Are Conspiring Against The Boltons
This is one that started and died during Season 6. Smalljon Umber, the new head of his house, brought Ramsay Bolton a gift, in the form of Rickon Stark (accompanied by Osha, and the head of direwolf Shaggydog).
But wait. The Umbers were total Stark loyalists. The Greatjon was one of Robb's fiercest supporters. Surely there is no way that they would betray an allegiance going back thousands of years? In fact, was that dog's head even Shaggydog's? No, it's definitely a trap, a conspiracy ploy by the Umbers to help the Starks take back Winterfell.
Oh.
Turns out that the Umbers really did betray the Starks, and Rickon, Osha, and Shaggydog all ended up as dead as this theory. Still, Smalljon had his throat torn out by Tormund, which is arguably even better.
