Season seven of Game of Thrones is truly underway, the third episode almost upon us. **Spoilers for episode two ahead**

Last week’s episode finished with a dramatic sea battle, Euron Greyjoy ruining Tyrion Lannister’s plans to take King’s Landing and almost killing Yara.

Notably, the final moments also saw Theon recede back into the cretinous Reek, jumping overboard rather than attempt to save his sister.

Despite some fans taking issue with Theon’s decisions, Gemma Whelan — who plays Yara — sympathises with the character.

Speaking at the London Film and Comic Con, via Radio Times, she said: "I think a really good point has been made and he has PTSD [Post-Traumatic Stress Syndrome].

Meanwhile, Euron actor Pilou Asbæk has hinted at the character’s fate, saying: “He knows his time is spare. He knows he’s going to die at one point. And if you ask me, it’s probably going to be spectacular. I hope so. But right now, he’s in for a ride.”
