Things have gone pretty horribly wrong for Cersei this season, culminating with her big scene in this episode. It wasnt all bad though, as at the end she met the newest member of the Kingsguard, and a reason for her to have some hope. The knight is glad entirely in armour, with the only visible part of him his eyes surrounded by pale blue flesh. He stands at around 7ft tall, and isnt far off that in breadth. As Qyburn reveals, he has taken a vow of silence until all of Cerseis enemies are dead. This is Ser Robert Strong, the mysterious project Qyburn has been working on all season, and widely believed to be the reanimated corpse of Gregor Clegane. Having The Mountain to do her bidding next year should help Cersei bounce back, and if The Hound were to also return then wed get to see the brothers face-off. CleganeBowl could be coming. Get hyped.
