So how would Mord the Jailer have returned to "Game of Thrones," exactly? As David Benioff noted when he and D.B. Weiss sat down with The Hollywood Reporter, the two had a perfect scene to bring him back — one set in a tavern. Apparently, the two thought Mord could just quietly own a tavern where other characters gathered. "Was it Brienne or The Hound [in the scene]?" Weiss mused, wondering about Gwendoline Christie and Rory McCann's central characters. "But we realized too late that Mord could have owned the tavern. We could have had that actor in the background acting exactly the way he did as a jailer, except now as a small-business owner. It was just such an obvious, no-brainer, day-after idea."

To be fair to Benioff and Weiss, there are a lot of characters in "Game of Thrones," and it would have been largely impossible to keep bringing lesser-known ones back into the fray to stand in the background. Sure, fan favorites like Hot Pie (Ben Hawkey) and Gendry (Joe Dempsie) ended up returning after long absences, but Benioff and Weiss completely abandoned major players like Daario Naharis (Michiel Huisman) and Jaqen H'ghar (Tom Wlaschiha) without any explanation. Considering how important those characters were, it's somewhat of a relief that the showrunners didn't leave them behind and bring back someone as ultimately inconsequential as Mord the Jailer.
