Last week's episode of "Game of Thrones" saw Arya Stark reuniting with Jaqen H'ghar at the House of Black and White.
The mysterious assassin became friends with Arya in season 2 when he agreed to kill three people of her choice. Although Jaqen asked Arya to accompany him back to Braavos, she refused saying she wanted to find her family.
But the two were reunited on Sunday's episode, and according to actor Tom Wlaschiha, Jaqen's association with Arya is not something that should be dismissed quickly.
"It's all part of a bigger plan," the 41-year-old German actor told The Hollywood Reporter. "We still don't know who Jaqen is and why he showed up in the story in the first place. It was never explained why he ended up in the black cells in King's Landing and then went on that journey. It wasn't a coincidence. It was all part of a bigger plan -- that's my theory."
Jaqen, who is part of a group called The Faceless Men, is the latest of Arya's mentors and Wlaschiha noted that the upcoming few episodes will possibly reveal his true motives.
"Even though [Arya]'s found [Jaqen], she's grown up and is much more conscious in her choices," Wlaschiha explained to Entertainment Weekly. "So he is going to teach her, as promised, but he is not going to make it easy for her. We will learn different sides of Jaqen and how the whole group at the House works."
However, Arya is not going to be just another recruit. "He definitely cares about [her]... The question is: If he's hiding it and why is he hiding it? Is it part of a bigger plan?"
Meanwhile, Vanity Fair noted that Jaqen could in fact be a long lost face from Arya's past. Reportedly, one theory has it that Jaqen and Syrio Forel, Arya's fencing instructor, are the same person.
The last we saw of the fencing instructor, he was up against Ser Meryn Trant and chances are high that Forel could be alive as we never saw the confrontation between Trant and Forel.
"Game of Thrones" airs Sundays on HBO.
