Conspicuous by his absence is Kit Harington's Jon Snow who was brutally stabbed in last year's finale.
In an interview to Digital Spy last month, Kit Harington had revealed that 'Jon Snow is dead.' He also hinted that his involvement in the upcoming season of the popular fantasy series would be 'very less.'
"I was hoping that there would be an outcry of 'why?' and 'oh god, no, no' rather than 'thank god.' That was the right reaction as far as I was concerned. People didn't want me to die, but he's dead. So there you go, everyone has to get used to it," the actor was quoted as having said.
Game of Thrones Season 6 airs on April 24.
