Deliberate mistake: After Ramsey shows Sansa her flayed northern friend, when it cuts to Davos riding the horse through the encampment one of the shots is flipped. Note his sword and his cloak's crossed straps have switched to opposite sides.
Deliberate mistake: During the "previously on Game of Thrones" snippets, before the opening credits sequence, there are two flipped shots of Sansa and Jaime as she tells him that she has always wanted to be there for Cersei's execution, but she won't get the chance. (00:01:45)
Chosen answer: The giants in general spoke little English and seem to generally speak very little at all and in a slow, lumbered manner, much the same as how they physically move. Wun Wun is acknowledging that he is supporting Jon's plan by simply stating his name of "Snow."
