(CNN) -- When "Game of Thrones" returns with season four, Kit Harington's Jon Snow is going to look a little different.

After that nasty bird attack and run-in with wildling Ygritte, the character's face "is not OK," Harington told Access Hollywood. "It's far from OK! I have to have scars this season. ... Then obviously I've been shot in the back with arrows, so, that hurt."

Even with those injuries, Snow is still as war-ready as ever -- and it sounds like he'll have to be in season four.

"He's a bit in the wars, old Jon Snow," Harington said. "And it doesn't get any easier this season. It's kind of high-octane, action-packed."

'Game of Thrones' fans freak out

Lena Headey, who turned heads at the Emmys in a lacy, sheer black gown, didn't go into details, but she did say that "the stakes are higher than they ever have been. ... It's just getting better and better."

And by "better," she could mean "bloodier." According to Harington, there will be "more deaths this season than any other! ... You'd think they'd tone the deaths down, but they don't. They've realized that's a successful option, so they're just killing more people than they've ever killed."

Lest fans worry that season four will be nothing but death, Harington confirmed that the HBO series will still have "plenty of sex."
