“Kissed by Fire” (Season 3, Episode 5)

This season-three highlight sees two couples bare both body and soul for very different reasons. Beyond the Wall, Jon and Ygritte consummate their relationship in a red-hot scene set in a secluded subterranean grotto. At the Bolton-controlled fortress of Harrenhal, Jaime and Brienne bathe together after their long captivity, and the exhausted Kingslayer explains the true story behind his nickname — he murdered the Mad King to save the people of King’s Landing, which he’d planned to level with wildfire — before collapsing in her arms.
