Game of Thrones Season 4 will be action-packed, according to Kit Harington. The actor who plays GOT's Jon Snow also said "some really important things" will happen next season.

"I've just finished reading (Game of Thrones Season 4 script) and I genuinely think it's my favourite one so far," Harington told Hero Complex at the recently concluded San Diego Comic-Con (SDCC). "It's very action-filled. Last season was a big impact season, this season is very action-packed. On paper it looks incredible, whether we can pull it off, who ... knows!" The last quip sounded straightforward, so fans can believe Harington was more than impressed with the GOT script, so far.

Last GOT season, Jon Snow finally made it back to his brothers at the Night's Watch. Ygritte (Rose Leslie), the Wildling woman he loved (and made him broke his celibacy vow) could've killed him for abandoning her. But she loved him too much to use her perfectly fatal aim on him. So she just sent him "home" to Castle Black severely wounded.

In the books, something even more devastating are bound to happen to Jon Snow and Ygritte. If you're a fan of romance, brace yourself. Then again, you survived the Red Wedding, didn't you?

"There are some really important things that happen for my character this season," Harington teased Hero Complex. "We're on a whole new journey now. There's a big divide in the books. And if we get to Season 5, it will all get even more complicated. So I'm enjoying the journey."

Harington is also quite insightful about his character Jon Snow. He said he has "devoured" George R.R. Martin's books, but had to stop because he already got to a point where Jon Snow has become so much different than who he was in Game of Thrones Season 1.

"Something changes in him when he realizes the world isn't always good, and his father died because there are bad people out there, and sometimes you have to rebel a bit."

Later in the series, viewers may or may not see how Jon Snow reacts when he learns that Rob and Catelyn had been massacred at the Red Wedding.
