Game of Thrones season 6: Character last seen in season 3 to make return

Mild spoilers and subsequent theories abound

Thoros of Myr (Paul Kaye) was last seen in Game of Thrones' third season

It's time to dust off your Game of Thrones box sets: an old character is returning for the HBO show's sixth season.

Thoros of Myr, the red priest seen wandering around as part of the Brotherhood Without Banners - will be making his first appearance since season three (episode seven, fact fans).

The news was confirmed via the website of actor Paul Kaye's agency which subtly stated: "Paul has also been busy with television roles, you can catch him in the eagerly awaited Season 6 of Game of Thrones.”

In case you've forgotten, the Brotherhood Without Banners is the group that runs into Arya (Maisie Williams), Gendry (Joe Dempsie) and Hotpie (Ben Hawkey). Thoros revives Beric of Dondarrion (Richard Dormer) after he's killed by the Hound (Rory McCann) in combat and is the one who hands Gendry over to Melisandre (Carice von Houten) in the name of the Lord of Light, consequently earning him a place on Arya's kill list.

Thoros gets a season five mention too: Tyrion (Peter Dinklage), when watching a Red Priestess' sermon in Volantis, remarks that she is "...much better looking than Thoros," describing him as the only red priest in King's Landing.

A source reportedly told fan site Watchers on the Wall that Thoros' appearance will involve a hanging.

He isn't the only season three character returning for the new season; Edmure Tully - the deceased Lady Catelyn Stark's brother - will return as will her uncle The Blackfish, which we included in our roundup of everything we know about season six.

With confirmed appearances of the Red Priest and Catelyn Stark's family members, forget John Snow: could season six introduce us to Lady Stoneheart?

HBO has released a few clips in the lead up to the release of the show's next season which will debut on 24 April at 9pm. It will be simulcast in the UK on Sky Atlantic at 2am as well as the following evening at 9pm.
