Season 5 of “Game of Thrones” has just ended, but fans of the HBO drama are desperate for more action. Although very few details about Season 6 have been released, the recent announcement of a character’s return has some theorizing about what the future may hold for Westeros.

Actor Rupert Vansittart, who portrays Yohn Royce in “Game of Thrones,” recently revealed to Flicks and The City that he’s set to reprise his role for a few episodes in Season 6. He confirmed that he would be present for the filming of the series in July and December. So what does that mean for the “GoT” universe? Potential trouble for Petyr Baelish (Aidan Gillen), aka Littlefinger.

For those that aren’t familiar with Yohn Royce, he is the Lord of Runestone. During Season 5 he agreed to take in Robin Arryn (Lino Facioli), the son of the late Lysa Arryn (Kate Dickie). However, Yohn Royce was far from impressed with Robin. Having been sheltered by Lysa Arryn his whole life, Robin lacked the skills a young lord should know -- sword fighting for one. Littlefinger, now the Lord Protector of the Vale, left Robin in Yohn Royce’s care to take Sansa Stark (Sophie Turner) to the Fingers and promised he’d return to check in on their progress. In reality, Littlefinger took Sansa to Winterfell with plans to marry her to Ramsay Bolton (Iwan Rheon).

He left Sansa at Winterfell when he received a raven from Cersei Lannister (Lena Headey). Upon returning to King’s Landing, Littlefinger backstabbed everyone by striking a deal with the queen. He asked to be appointed Warden of the North after telling her about the Boltons' plan to marry Sansa to Ramsay. Littlefinger promised to use his army of soldiers at the Vale to take down the Boltons and Stannis Baratheon (Stephen Dillane) and reclaim the area for the Lannisters.

Vansittart’s return as Yohn Royce means that Littlefinger could potentially follow through on his word to Cersei and return to the Vale to gather an army. But will Yohn Royce allow him to take an army to battle the Boltons at Winterfell? In the books, Yohn Royce is not pleased with Littlefinger holding the title of Lord Protector. Like the show, Littlefinger was cleared of involvement in the death of Lysa Arryn. However, Yohn Royce was still a “threat” to him, trying to remove him from power in “A Dance with Dragons.” It’s possible that that storyline could play out on-screen in Season 6, which would make it difficult for Littlefinger to gather his army for Cersei. If Yohn Royce really dislikes Littlefinger, he could warn the Boltons about the attack and betrayal.
