Kit Harington to return in Game of Thrones season six?

Actor Kit Harington, who played the role of Jon Snow in Game of Thrones since its first season, has sparked rumours that he might return in the upcoming sixth season of the fantasy drama series after he was seen sporting long hair, which were his character's iconic hairstyle.

Harington was photographed at a Wimbledon tennis match here with long tresses. Back in January, Harington -- who had revealed that he is contractually obligated to keep his hair long for the duration of the show -- appeared, with shorter hair at the premiere of his movie ‘Testament of Youth’.

The fact that he has now grown his hair back has sparked speculation that he will reprise his role as Jon on the fantasy drama series. One fan, Austin Chesshire, pointed it out on Twitter, and posted: “This is a recent picture of Kit Harington, notice his hair. He hasn't cut it. JON SNOW LIVES. #GameofThrones." Another fan named Tom Feeney wrote: "Jon Snow lives because of Kit Harington's hair."

Jon was last seen bleeding out after he was betrayed and stabbed in the fifth season finale. Addressing his character's fate on the show, Harington said in June: "I'm quite dead. It's over for Jon Snow - at the very least, he gets to join his family and kin and leave this terrible world behind."

However, his co-star Emilia Clarke, who plays Daenerys Targaryen, believes there is a chance that Jon would return to the upcoming season six. “There are some helpful people there, who could bring Jon back to life. If I had to bet, I would say it's a 50/50 chance,” she said .
