Does Jaqen H'ghar share Wlaschiha's admiration? The actor won't say, but he does suggest that the relationship between Jaqen and Arya is perhaps more predestined, or at least more purposeful, than one would initially think.
"From the beginning, he's somehow chosen her to be his apprentice," he says. "He wasn't in that cage for nothing. It wasn't just random. I think he always had a bigger plan for her. He's trying to teach her to the best of his abilities, even if sometimes that comes across as punishing or hurting her."
"I think Jaqen wants what's best for her," he continues, "because he has an agenda with her."
But Arya has an agenda of her own, according to Williams: "Arya this season will learn the most valuable lesson she has learned and will ever have learned. She's going to develop a skill that's going to come in handy and will benefit her for a very, very long time. I guess the people who are training her are going to almost create a bit of a monster. They're going to give away all of their best-kept secrets, and she's going to ultimately use that to her advantage."
In other words, Arya Stark lives, as much as she swears she's "No One" — and it's bound to be very bad news for more than a few someones.
