Among his favorite moments from the upcoming seventh season of the epic HBO fantasy series, Harington said acting with cast members he hadn't worked with before "and the interactions between so many different characters that we've been waiting to meet" was "the most exciting thing about this season."

"That's the thing I enjoyed most," Harington told ET. "I got to work with some friends, some very, very close friends who I've never worked with and I loved it."

"With certain people I haven't worked with for a long time... we'd be like, 'This is weird. Last time we worked together you were, you know, not yea high,'" he continued. "I haven't grown during this series, unfortunately, but yeah it's interesting. It's as [if] we've grown and developed and then been away from each other for all these seasons and then come back together."

While fans have already witnessed two intense GOT trailers, Harington promises some intense battle scenes for his character, Jon Snow, in the show's finale seasons.

"Safe to say that you'll see me in a battle scene," he shared. "I think that's a standard thing that happens now as we go into the late seasons… I think the one I'm involved with will be a really -- it's a way of making them different each year-- and this one is certainly different. It's certainly, um, ambitious."

As the series begins to wrap up, one thing that Harington dislikes while being on set is the paparazzi's constant attempts to figure out GOT spoilers, even going so far as to fly drones over filming locations. "I think we all got very upset and angry that people wanna spoil a TV show in that way for people," he said.

"I think we did everything we could," he added about the measures to preserve secrecy. "There's only so much you can do when you're filming in these beautiful locations and you can't shut places off.You just have to deal with these, frankly, a**holes who wanna spoil it for people. I know there's money involved, but I just got so… I'm so protective over this show now. I'm so fond of it and as it gets towards the end, and all these exciting things happen, which I want to be shocks for people, it really infuriates me when I see someone ruining that [for] people."

As far as what he thinks of the overall series, Harington revealed that his favorite character is Bronn, the most worthy character to sit on the Iron Throne is Tyrion and that he'd love to see Catelyn Stark come back to life and Grey Worm and Brienne team up before the show ends.

He also said he'd like to see Snow "smile, [a] big smile" before he dies (again) and revealed that there's only one thing that he's ever wanted to keep from the show and has "hinted so heavily" at.

"I want my sword. I want Longclaw," Harington shared. The actor explained that, since the first season, he's been asking to keep Snow's sword when the hit HBO series ends. "As the seasons went on and the show became more popular, and that sword's value went up, and up, [they got] slowly quieter about it. And that's why I'm hinting more and more. I'm like, 'No, seriously. I want that sword,' and they're like, 'Mmm.'"
