The last time that anyone saw Yara Greyjoy was in the utterly depressing 'Game of Thrones' episode from Season Four when she marched into Dreadfort to try and rescue her younger brother Theon. Since then, Theon Greyjoy has been abandoned by the Ironborn to become a slave of Ramsey Bolton.

Or have they?

In an interview with British Comedy Guide, Gemma Whelan has confirmed that she is returning to 'Game of Thrones' Season Six, but only after she has been found out.

"Even when I said I'm going to Northern Ireland on Wednesday to you just now, I thought 'Oh god, maybe I shouldn't say that,'" she said. "You really watch your back on everything - 'don't say too much'. But at least it's been leaked that I'm going to be in it, so I can talk freely about that."

The English actress also spoke up about how 'Game of Thrones' executive producers David Benioff and D.B. Weiss knew what would happen next in the show. It's because they already know the storyline in 'The Winds of Winter,' the yet-unreleased sixth book in the series 'A Song of Ice and Fire.'

"Yeah, they've sort of... not run out of books really, but they've liaised with George R.R. Martin who writes the books, and gone off on their tangent, with his approval," Whelan said. "So that's why people are even more interested in spoilers. It's funny isn't it, there's no other show like it."

Gemma Whelan also admitted that she worries when she reads through the 'Game of Thrones' scripts on whether Yara Greyjoy would be killed off, although her character's death wouldn't stop her from hanging around the Belfast airport.

"To confuse people!" she said, adding, "Although hopefully you'd have more good things to do at the time."

The comment sounded a lot like what people were hoping for when Kit Harington was spotted in the Belfast airport after arriving from the same flight as Tom Wlaschiha, who plays Jaqen H'ghar in 'Game of Thrones.'

Although Jon Snow has been confirmed to be dead in the series, the actor is currently shooting scenes in Ireland and fans believe that the character will be resurrected and eventually adopt a new name.
