Riddell

Riddell is a minor character in the sixth season. He is played by Ross McKinney and appears in the episode, "No One".

Background
Riddell is a member of the Brotherhood Without Banners. It is not clear whether he was one of the rogue members, but it is possible as he is in the company of Gatins and not with the main group.

Season 6
Gatins is bragging about what an excellent kisser he is and asks Steve and Riddell if they want to learn. Riddell watches closely as Gatins begins to demonstrate on Steve, which turns into a prank. Riddell and the others see Sandor Clegane walking up behind Steve, whom the Hound beheads. Before Riddell can run, he is impaled in the chest by the Hound.
