It's official: 'Game of Thrones' has resumed filming, and the HBO series has brought most of the main cast back to Ireland.

Watchers on the Wall has reported that Emilia Clarke, Nicolaj Coster-Waldau, Alfie Allen, Isaac Hempstead-Wright, Sophie Turner, John Bradley, Nathalie Emmanuel and Jacob Anderson have all arrived in Northern Ireland. Even Brenock O'Connor, who played Ollie, has been spotted in Belfast.

However, there is only one actor that fans wanted to see: Kit Harington.

There have been previous reports that Harington has been seen in Belfast with his long Jon Snow dark curls still intact. Unfortunately, there has been no photographic evidence to assure 'Game of Thrones' fans who have now decided to put up #HairWatch.

Luckily, Watchers on the Wall were quick to snap photos of Kit Harington at the Belfast airport. The actor had reportedly flown in on the same flight as Tom Wlaschiha, who plays Jaqen H'ghar.

The pictures show that Harington has pulled back his Jon Snow locks into a manbun.

Although there are speculations that Harington might simply be filming a funeral scene like Rose Leslie and Charles Dance, Jon Snow fans have collectively breathed in relief that he will return in Season Six.

#HairWatch is the hashtag assigned for Kit Harington's hair, which has been the subject of several speculations that Jon Snow will return in the sixth season of 'Game of Thrones.' The actor has previously spoken about wanting to cut his hair when his character is killed off in the show.

Season Five ended with Jon Snow being murdered by his Night's Watch brothers, and Harington himself has repeatedly confirmed that the character is dead. However, Harington has yet to get a haircut. His appearance at the Belfast airport has only fueled the possible Jon Snow resurrection rumors.

See Kit Harington in the sixth season of 'Game of Thrones' when it airs next year.
