She's definitely really struggling. I think she thought that she'd got him out of a system but when she’s put in a situation where he’s telling her how much he likes and laying it all on the line, then she’s definitely very much still tempted.

It’s really difficult because on paper she's happily married, she’s kind of got it all. But I think what he gives her is this escape from reality, this escape from the dishes, the mundane of life. Damon suddenly appeared and made her feel excited, and wanted and desired. The fact that he’s chased her so hard has made her feel attractive again. She knows she shouldn't be doing this but it's really exciting.

I think there is an element of that, ‘oh my God, I shouldn't be doing this, oh my god, what if I get caught’ and it's giving her that frisson, that excitement. Earlier on she tried to tell him what they were doing was awful, she wasn’t enjoying it at all and didn't want to do it anymore but actually I think she is secretly kind of enjoying the danger.

Yeah I’ve loved it, it’s been great fun, we’ve seen her in a different light. Some of the comments I’ve been getting about her behaviour are awful, they think her behaviour is disgraceful but then there are others saying that this is real life, affairs/flings they happen. It’s important to show that yes Sarah is usually very well behaved, yes she is happy but this man has just got under her skin. We’re seeing her make bad decisions that aren't necessarily the best for her but she's still making them so yeah it’s really interesting to play. There’s not much of a moral reason for her behaviour, she claims Adam’s been a bit missing in action at one point and been too busy with work but it’s more of an excuse for the way she’s acted so I can't imagine it's going to go down very well.

Sarah’s not going to be very popular! She compounds the problem and basically tries to  convince Harry that it didn't happen or maybe he's imagined it. She pretty much tries to gaslight him which is followed by major, major guilt and I think that a realization that she can't she can't do this anymore, this isn't right and she can't behave like this. So there's going to have to be a coming clean really.

If Harry hadn’t seen anything, I don't think Sarah would have ever said anything. She thought it was done with and when Damon comes to the flat, although she has a moment of temptation, it’s also that realization of I can't do this anymore. Although she loves the excitement and the idea of a fling, the reality of it is completely different. She knows she’s got so much to lose and she doesn't want to lose what she has. But then when she realizes her son knows, although she's trying to come up with ways to keep him quiet and get rid of the problem, I think that's the point where she knows she’s going to have to come clean. She knows she can’t do this to Harry, it's not fair.

It’s just the worst and the guilt is incredible. When she tries to explain to Adam why, she confesses it was lust basically, it was an escape from just being someone’s mum, someone’s wife, someone at work.

She's just basically about to throw grenade into the marriage, so I think 10 out of 10, she's off the scale scared. She knows it's coming, she knows she's got to sit down and she knows she's got to tell him but it’s that anticipation and the fact she knows he hasn't got a clue as well. The guilt, the feeling of disgust at herself and also the realization that she could potentially have ruined everything are just overwhelming because she does still really want to be with Adam.

We've worked really really well together and it’s been great. We’ve both worked really hard and we’ve found a really cool shorthand as well now. There’s been a lot of two handers in the flat that we’ve worked very hard on but being with Sam has made even the tough days easy. The scenes have just been so well written because I could really identify with everything that she was saying, and I could identify with what he was saying too. It just felt very real and we’ve really enjoyed it.
