Innkeeper

An ​innkeeper ​is a minor character in the fourth season. He is played by Martin Walsh and only appears in "Two Swords".

Season 4
When Arya Stark and Sandor Clegane arrive at his inn, the innkeeper is begging Polliver to stop his men from raping his daughter. Polliver tells him to shut up and pour them more ale, or they may take her with her when they are done with her. The innkeeper reluctantly pours them more ale.

In the books
In the A Song of Ice and Fire novels, Sandor warns the innkeeper that Polliver and the Tickler (who is still alive at this point, though killed by Arya in the ensuing fight) will kill him instead of paying for their drinks. This causes the innkeeper and the other people to leave the room.

This innkeeper's story is more similar to a story Arya hears Chiswyck, one of the Mountain's men, telling at Harrenhal. He recalls that after the Tourney of the Hand Ser Gregor Clegane and his men gang raped Layna, the daughter of the keeper of an inn on the Goldroad. Chiswyck estimates her to have been eighteen at the time of the rape, but Rafford corrects him by stating that she was only thirteen. The men find this hilarious, which angers Arya and influences her to name Chiswyck as the first to be killed by Jaqen H'ghar.
