For the fourth week in a row, HBO’s Game of Thrones hit a series high in the ratings.

Sunday night’s 9 p.m. telecast delivered 5.5 million viewers. Across two plays, viewership also hit a new gross nightly high with 6.8 million viewers, surpassing the third season’s debut evening for the first time (premiere night had two replays instead of the usual one).

EW’s recap of Sunday’s episode, appropriately titled “The Climb,” is here.
