Riddell was a member of the Brotherhood Without Banners.
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.
