The new episode of "Game of Thrones" marks Arya's march into the House of Black and White. In the promo for the episode titled "High Sparrow," the Stark daughter will again meet her old friend Jaqen H'ghar, who will help her into becoming a Faceless Man, a servant to the Many-Faced God.

However, her transition seems to be part of a far greater scheme Jaqen is cooking up. Actor Tom Wlaschiha, who returns as Jaqen H'ghar in the series, said in an official Production Diary interview on Making Game of Thrones that "it seems like there's some bigger plan behind it."

"We still don't know why Jaqen showed up in the first place. It always seemed kind of strange to me that he, with his abilities, would be a prisoner in the black cells in King's Landing," the actor shared. "We still don't know what his secret agenda is – or if there is a secret agenda," he added.

Wlaschiha added that his character did not expect "that she was actually going to find him" despite the fact that the coin was already an invitation that she should. He also explained that Jaqen is testing her, "to see if she's really serious about [the House of Black and White endeavor]."

"I love the scene where she sits outside in the rain all night repeating the names over and over again," Wlaschiha shared, gushing over Arya's strength of mind. "She's so determined," the actor then admitted.

As for the rest of the action in the upcoming "Game of Thrones" episode, fans should gear up for Jon Snow's first day as the leader of the Night's Watch. He has enemies now and he will make more for sure. There's Ser Allister Thorne—looks like there's no peacemaking between them in the near future.

Sansa is on her way to avenge her father and brother but she intends to do so with Littlefinger. Fans will also see what the Boltons are up to now in the Winterfell. "Game of Thrones" season 5 episode 3 "High Sparrow" airs Apr. 26 on HBO. Alternatively, it can be watched online through live stream with HBO GO.
