The episode title comes from the quote 'No Mourners, No Funerals' which is repeated as a message of good luck amongst the Crows in the Six of Crows duology.
Nina (Danielle Galligan) suggests running away to the Wandering Isle because she would fit in with no problem, and says so in the Wandering Isle accent. The Wandering Isle is based on Ireland, and Danielle Galligan is from Dublin, Ireland.
