Shock flashback scenes in Thursday night's episodes confirmed that Moira was responsible for pushing Emma from the viaduct in October.
Moira lost it when Emma cruelly taunted her over the tragic death of her daughter Holly. In a sinister twist, Emma was deliberately trying to push Moira into killing her, because her strict religious beliefs stopped her from taking her own life.> Related Article Emmerdale star teases future for Cain and Moira
Digital Spy paid a visit to the Emmerdale set on Thursday for the first interview with Natalie J Robb, who plays Moira, about this killer twist.
Soap deaths rarely go unpunished, so did you worry this storyline might mean you'd have to leave the show?
"They told me that wasn't the case. If it happened, it is in the lap of the gods and there is nothing I can do. I have just signed for another year, so you have another year of me yet!
"Robert Sugden has murdered, but he is still here. I was quite grateful to be involved with it, to be honest. When they described it to me, it hadn't been written at that point. I enjoyed all the twists and turns and curveballs. It was nice to be part of that."
When did you know it was Moira?
"From the start, but they were going to do three alternative endings, so none of us really knew and that was because of leaks. When Holly died, it was such a shock, as nobody saw it coming and that is much better for the audience.
"So they filmed endings with Ross and Pete being the killer, too. They could have even put them on instead at the last minute, but the next six months wouldn't make sense then! (Laughs.)
"Emma wanted Moira to do this from the off. Moira was not being calculative about it. She didn't go to murder Emma, she wanted to bring her down. But Emma pushed the wrong buttons – don't talk about the kids in the wrong way! Don't push Moira when she's angry!"© ITVAdvertisement - Continue Reading Below
Was Moira aware that Emma was trying to absolve herself from the sin of suicide by taunting her into this?
"Yes, she was a little bit. When Moira was there, Emma makes that decision – Moira will be the one who pushes her, when really all she wants to do is save her. Emma smiled when she fell. Now Emma has got Moira, she has won, as all of the pain and guilt will be onto Moira. So Emma was calculating right to the end!"
Moira has now chosen to confide in Cain...
"Yeah, as Cain definitely sussed that there was something not quite right – the guilt. Moira just couldn't cope with it all really, so he was the one Moira confided in first."> Related ArticleEmmerdale star reveals Ross's future after Emma story
For Moira, is it a relief to have now confessed to someone? Will this help her sleep again?
"Totally, but she still has a small baby!"
Was it the guilt keeping Moira awake, more than her struggles with Isaac?
"Yes, it was to do with that, really. We had to play a bit of post-natal depression so that it wasn't so obvious that she had murdered someone, although the baby blues were part of it as well."© ITV
Why didn't Moira tell Cain sooner?
"She was that shocked by what she has done, that her emotions were all over the place. She was like: 'What do I do?' It was all these things. Cain is the closest one to her, but there are other people that find out as well."
Can Moira move on from this?
"She does go a wee bit mad, but she holds it together again and that is a lot to do with Cain, and also Isaac and Adam."
Emmerdale airs weeknights at 7pm on ITV, with an extra episode at 8pm on Thursdays.
