So, I'm a guardsman here at the Red Keep, and a the queen's just come back from being prisoner to the High Sparrow and his fanatics. We're waiting at the gates for her when her Maester, Qyburn, comes strolling up with this giant of a man on his heels! The fellow's in Kingsguard armor, carrying one hell of a big sword, and he never says a word.
Who is this stranger? I've not seen a person so massive in stature since The Viper felled the Mountain (right on top of himself, fookin' hilarious), and there's no question that Gregor Clegane's a headless corpse, what with the Queen sending his head to Dorne and all...so who is this Robert Strong? I've never heard of a noble family named Strong, never met any knights named Strong, and to be honest, a name like that would be more suitable for a bastard than a Kingsguard. Where did he come from? What are his qualifications?
Can just anyone who's bleeding lethal with a weapon be a Kingsguard?
