Jon edged Tyrion by one minute. Tyrion earned himself 337 minutes of screen time, and Jon Snow now has 338.
DaenerysTargaryen was third on the list, but the gap is significant. The Mother of Dragons has 276 minutes which is more than an hour less than Jon and Tyrion.
The Lannisters and Starks take the next spots. Sansa was fourth with 239 minutes, followed by Cersei with 236 and Aryawith 224 and Jaime who has 199.
SamwellTarly, the character who has appeared outside of the three major families, has been on screen for 144 minutes.
The dead character with most screen time is Littlefinger. He appeared for 119 minutes.
Ned Stark, who was killed nine episodes of the show has the 13th most screen time of anyone. Ned got almost the same screen time in one season than Littlefinger got in seven.
