Rickon Stark is making his return to Game Of Thrones for the first time in three seasons, actress Maisie Williams, who plays his elder sister Arya, has confirmed.
Williams let the news slip during an interview with BBC Radio 1, reports dailymail.co.uk.
When a caller asked if viewers would get to see the youngest Stark child again she replied: "Yes, we will indeed".
But when she suddenly realised she might face the wrath of the showrunners for letting the spoiler slip, she added: "Oh no, I'm literally going to go off the air and someone's going to email me!"
Rickon Stark, played by 14-year old Irish actor Art Parkinson, has not been seen in the series since the end of season three, when he was travelling with his brother Bran, Hodor, Osha, Jojen and Meera Reed, and the boys' pet direwolves Shaggydog and Summer.
Episode three of the sixth season of Game of Thrones titled Oathbreaker will air on Star World Premiere on May 10.
