New Jon Snow rumors are flying following Kit Harington's arrival in Belfast on Monday.

The 28-year-old English actor sparked fresh hope he will return as Jon on Game of Thrones season 6 after a fan spotted Harington landing in the Northern Irish capital. Tom Wlaschiha, who portrays Jaqen H'ghar, was on the same flight.

Although Harington and Wlaschiha's characters both appeared to die on the season 5 finale, the actors' co-stars are currently filming in Belfast. Emilia Clarke, Maisie Williams and Sophie Turner, who play Daenerys Targaryen, Arya Stark and Sansa Stark, have all been spotted.

Clarke and Williams previously addressed Harington's possible return, with the former telling MTV News there is a "50/50 chance" and Williams outright dismissing the idea to E! News. The actor himself claimed he is not coming back in an interview with Entertainment Weekly.

Game of Thrones is based on the A Song of Ice and Fire book series by George R.R. Martin, and will return for a sixth season in 2016. Peter Dinklage also stars as Tyrion Lannister, with Lena Heady as Cersei Lannister, Aiden Gillen as Petyr Baelish and Natalie Dormer as Margaery Tyrell.
