Emmerdale’s Robert Sugden (Ryan Hawley) will resort to drastic measures next week when Chas Dingle (Lucy Pargeter) finds out he has reignited his fling with Aaron Livesy (Danny Miller). Robert, who also had a part to play in the death of Katie Sugden (Sammy Winward), will apparently try to kill Chas when she threatens to tell his wife Chrissie (Louise Marwood) the truth. When his own attempts to murder her don’t go to plan, he turns to a hitman. Speaking about the storyline, Ryan told Digital Spy: “He's absolutely desperate for Chrissie not to find out. He loves Chrissie, but he has developed this attraction for Aaron, who is interesting, different and exciting. “When Robert picks up the rock, he's at a point where he is absolutely desperate because Chas isn't going to back down. She is a strong-willed character and there's a personality clash between the two of them.” Robert and Chas in Emmerdale (image via ITV). He continued: “Chas is going to call quits to it by revealing the truth to Chrissie, and there's no way Robert will let that happen. We've seen that with Katie - he won't let it happen and we don't know what lengths he will go to in order to stop her.” And it doesn’t sound like the drama is going to stop there as Robert will be involved in some of the soap’s big summer plots. Ryan explained: “There's a very, very big summer they've got planned. “I was told a brief of what we're going to be doing for the next few months, and so I'm kind of balancing myself between thinking about that and what we're doing now. The summer sounds like it's going to be unmissable.”
