Cleganebowl will happen, y'all.
GOT fans have been hyping up the idea of "Cleganebowl" since the series began, waiting with bated breath for the moment when brothers the Hound and the Mountain will finally face off in a fight to the death. If it's ever going to happen, it'll happen in season eight . . . but considering the Hound's vaguely threatening warning about "who is coming" in the season seven finale, the Mountain seems to have other threats on his horizon.
