"Game of Thrones" has continued to break ratings records since the premiere of its forth season on April 6.

According to Entertainment Weekly, the fifth episode of the season drew in 8.6 million viewers. The ratings have continued to grow, reportedly averaging 17.8 million viewers across all platforms, which is up 24 percent from the previous season.

And season four of "Game of Thrones" isn't slowing down any time soon. Aidan Gillen, the actor who plays Petyr Baelish in the hit series, explained to EW how his character will develop throughout the season, teasing his relationship to Sansa Stark.

"For me the season is about developing more of a parental and surrogate parental side - the sweeter side of Littlefinger comes through, as well," Gillen told EW. "I'm off on my travels and laying plans. He's always laying plans, [this is one of his] meticulous and far-reaching plans, geographically and generationally, even. So it's quite interesting. Am I being cryptic enough?"

However, Gillan admitted Sansa isn't safe in the hands of Baelish, but he does have his reasons to keep her alive.

"Well, there's the obvious," Gillen told EW. "The obvious connection of Sansa being Eddard Stark's daughter. There's also somebody there who holds some intrigue. I feel I can teach her, and take her under my wing. But I have a feeling she may have her own agenda."

"He's dangerous. People tend to refer to Varys and Littlefinger as the characters who are the most dangerous," he said. "Dangerous in that you're not sure what his game is or where his allegiances lie. You know, he's keeping a lot of options open and playing the long game."

"Game of Thrones" airs on HBO Sundays at 9 p.m. EST. You can watch the trailer for episode six in the video below.
