16. "Mockingbird" (Season 4, Episode 7)
Melisandre bathing au naturel, Daenerys ordering the sexy sellsword Daario Naharis to strip on command: There's hot stuff aplenty in this one, if that's what your after. But "Mockingbird" is memorable for what children say rather than what grown-ups show. Arya Stark delivers the series' most nihilistic line, about the big nothing that awaits us after death: "Nothing isn't better or worse than anything. Nothing is just nothing." But her old, fat friend Hot Pie unintentionally utters an optimistic alternative when holding forth about the importance of condiments: "You cannot give up on the gravy." Hope, the episode argues, goes well with any dish.
