6. Rickon Stark
With Bran Stark seemingly on his way to becoming a tree, Rickon Stark is the only legitimate living male offspring of Eddard Stark that remains alive, though the majority of the world believes him to have been killed at the hands of Theon Greyjoy. Few know the truth that Rickon and his brother Bran escaped from Winterfell and two orphan boys were killed and presented as their dead bodies but one is Wyman Manderly, the lord of White Harbour who learned of the charade from Wex Pyke, a surviving Ironborn from Winterfells sacking. Though he has feigned loyalty to House Bolton and the Iron Throne (showing his commitment by displaying the body of the visiting Davos Seaworth), Lord Wyman has continued to support the Starks in secret and has enlisted the help of the very-much alive Davos to bring Rickon back from the savage island territory of Skagos. Last seen with Osha, Rickon will be older than the last time we saw him if and when Davos does locate him, and the revelation that he is in fact alive will surprise many prominent Westerosi figures and throw a spanner into the Bolton plot to secure the North for themselves through Ramsays marriage to a fake Arya Stark.
