Sam and Bran unearthed the link between Jon and Dany, revealing that he wasn't Ned Stark's illegitimate love child and was actually the son of Lyanna Stark and Rhaegar Targaryen.
In the first episode of the final series Samwell finally dropped the bombshell on Jon revealing that he was the King of the Seven Kingdoms.
