Arya Stark's reaction to Lady Lysa Arryn's death and Arya's psychotic laugh.
The Hound brings Arya to her aunt Lysa Arryn and when Sandor Clegane/The Hound and Arya finds out Lysa Arryn is dead Arya laughs because The Hound has been taking Arya everywhere to have a reward but because Arya's family and relatives keep on dying The Hound doesnt get a reward and winter is coming.
