17. "The First of His Name" (Season 4, Episode 5)
The start of a hot streak that would carry Season Four all the way to the end, this episode was a sort of Westerosi Ladies' Night. Cersei Lannister toned down the wicked-queen vibes and had heart-to-hearts about her surviving kids with her enemies Margaery Tyrell and Oberyn Martell. The Stark sisters, Arya and Sansa, learned hard lessons from their sinister guardians (the Hound and Littlefinger, respectively). And the viciously abused wives of the wildling warlord Craster got their revenge, helping defeat the rogue Night's Watchmen who assaulted them, then burning their house of horrors to the ground. Fire and blood, as they say.
