Tywin Lannister
As we all know, “A Lannister always pays his debts” – that’s not someone you want to mess with! It appears that the showrunners recognized this and crafted him eerily similar to his literary counterpart. You have to admit that Charles Dance bears an uncanny similarity to the AI portrait, and his portrayal of Tywin is equally cruel and clever. Interestingly, in both the texts and the show, he is killed by his son on a porcelain throne.
Jaqen H’ghar
You’d think a fantasy hitman would desire to remain anonymous, but Jaqen H’ghar, the faceless men, clearly prefers aesthetics over obscurity. Seriously, who wouldn’t notice a guy with half-red, half-white hair? At least in the show, when he’s played by Tom Wiaschiha, they take a more modest approach to this commanding appearance, merely giving him a small white patch. In the novel, Arya is reminded of Syrio Forel when she looks at him, which lends credence to the fan idea that they are the same person.
