Read an interview with actor Rory McCann, who plays Sandor Clegane (the Hound) in Game of Thrones, in which he discusses his character’s changing relationships with Joffrey and Sansa in season 2, and working on the show. Beware of spoilers.

On the Hound’s relationship with Sansa, which takes a new turn in season 2, Rory tells Access Hollywood:

He’s going to be in conflict, I think. I think he wants to look after Sansa and totally understands her position, but he’s also in a position [of] — if he steps in, he is risking his life… I think in the first season you can see with Sandor and Sansa, that there’s a frustration with Sandor trying to get through to Sansa that it’s not all fairytale and true knights and there’s so much badness in the world. But, by the end of the first season, obviously she’s seen… her father having his head cut off. So she’s maybe seen the light now, but I think there’s still a frustration of trying to [get her to] see the reality of the whole situation. It’s giving advice to Sansa for survival, basically.

He also talks about working on the set and how the cast and crew work to keep their energy up during the taxing shoots:

It’s things like during the night shoots, you’ve gotta try and keep your spirits up. The night shoots this season — the weather was brutal and so anything to cheer up anyone. But it’s was usually just telling stories… I have a guitar on set, as well. I play little ditties and stuff. There’s usually someone else with a guitar as well. There’s usually a jam going on. The kids love that classic Glee song. You know, the Glee song. The one that goes (starts singing) ‘just do it, I’m just a na-na-na…’ You know that one?
