HBO has unveiled new pictures from "Game of Thrones" Season 6 episode 3 titled "Oathbreaker," that will see Arya training to be No One, Tommen confronting the High Sparrow and Daenerys meeting the future.

According to Watchers on the Wall, the episode will also feature the first appearance of Samwell Tarly and Gilly this season. The characters were last seen in the penultimate episode of Season 5, when Jon Snow granted the duo permission to leave Castle Black so Sam could head to Oldtown and study to become a maester.

John Bradley and Hannah Murray, the actors who play Sam and Gilly, have been mum on what the future has in store for these two characters, but Murray revealed she was excited to have a new costume.

"When we were at the premiere in San Francisco last year, Dan Weiss came up to me and said, 'Two words, new costume,' and I've never been so excited in my life," she told Entertainment Weekly. "I had one costume the whole way through the show...It's like a variety of sacks layered over each other. In Season 4, I got really excited because they gave me an apron."

The official synopsis for "Oathbreaker" reads: "Daenerys (Emilia Clarke) meets her future. Bran meets the past. Tommen confronts the High Sparrow (Jonathan Pryce). Arya (Maisie Williams) trains to be No One. Varys (Conleth Hill) finds an answer. Ramsay gets a gift."

In the US "Game of Thrones" airs Sundays at 9 p.m. EDT on HBO and the fantasy drama airs in India on Star World Premiere HD every Tuesday at 10 p.m.
