Beth19 posted a topic in E06: Beyond the WallSam, Gilly, and little Sam. There are obvious parallels between Samwell Tarly and Samwise Gamgee from LOTR. They are both devoted sidekicks to the hero, chubby, responsible, and exhibited unexpected bravery. I know that LOTR and Tolkien were one of the many influences on Martin. It would be cool if, as one of last shots of the entire show after everything is done and the war is fought, Sam brings Gilly and Little Sam back to Horn Hill and says something like "well, we're home" and shuts the door.
