Daryl’s relationship with Carol is another interesting part of the show. How would you like to see that develop?
"I don’t want to see those two making out against a tree - I’d rather leave that to other characters that get introduced. But I like how damaged people gravitate towards damaged people and have this sort of kindred spirit. They see the damage in other people that they have in themselves.
"I always find it more interesting that you have someone’s back for reasons that are very similar to yours, rather than just, ‘I want to make out with her’, y’know?"
How is filming coming along on season three?
"It’s amazing. It’s kind of intense - I have a bigger role this year so there’s a lot more for me to do, I’m working quite a bit, but it’s good work and I think this season is going to blow away last season."
How is your role different this year?
"Well, I’ve kind of stepped up in certain areas, so there is more for me to do. Shane (Jon Bernthal) left last year and he was a big part of the storyline - we have a lot of new characters, it’s sort of spreading out. I don’t want to give anything away, but I’ve sort of become Rick’s right hand man in a way, so I’m doing a lot of physical stuff."
