'Game of Thrones' Kit Harington teases 'tempestuous' Jon Snow romance

Kit Harington has revealed new details about the second season of Game of Thrones.

The actor - who plays Jon Snow on the HBO fantasy drama - told MTV News that his character will have a "tempestuous relationship" with new character Ygritte (Rose Leslie).

"I'm not allowed to go into details... but I will say that it's nice for Jon to meet a woman," he teased. "Watch this space, honestly - [Rose is] amazing."

Harington also hinted that Jon will have a more action-packed role in the new episodes.

"Jon gets to fight more," he confirmed. "In the first season, it was all training yard stuff, and the world he's going into [this season] is very much more real. The fighting he has to do, it's for real. It's not play fighting."

He added that the popularity of Game of Thrones seems to be "snowballing" throughout the world.

"It keeps getting more momentum," he admitted. "I think it's one of those things - a TV show, the longer it's out there and is doing well, word of mouth spreads it around, and then more and more people watch it. It's... fantastic for us."

Game of Thrones will return on April 1 on HBO in the US and on April 2 on Sky Atlantic in the UK.
