Game Of Thrones: 10 Crazy Things To Expect Next Season

4. Ser Robert Strong

It's no big secret among both book readers and show watchers that Ser Gregor Clegane didn't truly die at the hands of Oberyn. This was all but confirmed near the end of last season, when we saw an all-new scene in which Qyburn is seen experimenting on Clegane's barely living body. In the books, a mysterious 'Ser Robert Strong' is frequently mentioned, and at one point put forward by Cersei Lannister as her champion. It's never explicitly revealed who Ser Robert Strong actually is, although he's described as being eight feet tall, rumoured to never eat or drink, never speaks, and never removes his greathelm. He hasn't come into action yet in the books but, with the way the series is headed, that is unlikely to prevent the show makers from showing off this Frankenstein's monster.
