Gendry
There are so many “true” kings and heirs and whatnots going around Westeros. You’d think someone would’ve kept better tabs on Gendry. He is, after all, the only known heir of the late King Robert Baratheon. But after Davos smuggled him to safety at the end of the third season, we had to wait four years for any sign of him. How the hell did we lose track of a guy for four years?
