Along with Kegs and Mully, he travels to the brothel in Mole's Town. They sit drinking and listening to a whore belching out the melodies to popular songs. Jack correctly guesses that she is belching "The Bear and the Maiden Fair". She compliments him on his hearing, but quips that it is a shame that he has a hangnail for a penis. They are later slaughtered when a group of wildlings led by Tormund and Styr attack the village. News of their deaths soon reaches Castle Black.
