'Game of Thrones' season 7 spoilers, plot news: Arya to continue on her quest for revenge?

Arya (Maisie Williams) was last seen taking revenge on Walder Frey (David Bradley), and it looks like she's moving on to her next target.

Previously on "Game of Thrones" season 6, Arya had cooked up a meal for Walder Frey consisting of his sons and had taken his head right after she revealed herself. She already started on her path of revenge on all the people that have wronged her family, and Walder Frey was first on the list.

HBO released a sneak peek of what's to come for the network in 2017, and in the "Game of Thrones" snippet, Arya was seen riding a horse wearing a northerner's outfit.

According to Inquisitr, Arya could have taken a horse and some clothes from House Frey before going to Winterfell. In reference to the compiled spoilers on Reddit, Arya is still on her mission to finish the Frey brothers. She will use the face of Walder Frey and call the Frey sons to a gathering, where she will poison all of them, except the women and children of the house.

Meanwhile, does Varys have an agenda regarding the Iron Throne?

There are speculations that Varys already knows about Jon Snow (Kit Harrington) being the rightful ruler of the Iron Throne, given that he is the son of Rhaegar Targaryen.

Since Varys knows everything about the Seven Kingdoms, including secrets, he must also know about Jon Snow and his right to the throne. But in "Game of Thrones" season 6, Varys is supporting the claim of Daenerys (Emilia Clarke) to the throne. Is it possible that Varys does not really mean that he wants peace to rule in the Seven Kingdoms like he says he does and that he has a hidden agenda with regards to the Iron Throne?

"Game of Thrones" season 7 is expected to debut in 2017 on HBO.
