Failing to realise that Aaron Livesy is the person in question, Katie jumps to the conclusion that he is secretly seeing Alicia Metcalfe, a situation that Robert quickly tries to turn to his advantage…
Here, Ryan Hawley – who plays Robert – chats about the drama to come.
How is Robert feeling about his relationship with Aaron?
"It's a really exciting and thrilling relationship because nobody else knows about it. Robert goes to Aaron to get all of the fulfilment that he doesn't get from Chrissie. He likes the danger, too. Robert is very devious and he loses interest very quickly, so Aaron is his next project."
How would you describe Robert's feelings for Aaron?
"In Aaron, Robert sees someone who he can be himself around. Aaron possibly knows him better than anyone else to some extent. He is also someone that Robert finds very attractive and he's gratified by him in that sense too."
Moving forward, would Robert be happy to marry Chrissie while continuing to have Aaron as his bit on the side?
"With the way things have been going, that's a dilemma that Robert is going through and it's not really clear what his final choice is going to be. He's still going through that, so we'll have to see how that pans out.
"I'd say there's absolutely no way he will throw Home Farm away, even if he fell head over heels for someone. Home Farm is his big flagship trophy."

Aaron and Robert
Does Robert feel guilty about betraying Chrissie?
"Yes, because Robert genuinely does love Chrissie. I imagine that when they first met, Robert had finally found someone that he was excited by. She was smart, sophisticated and many other things that he hadn't experienced in a woman before.
"Robert certainly wouldn't want to hurt Chrissie's feelings. If his relationship with Aaron were to come out, it would upset Robert purely because of how Chrissie would feel."
How does Robert feel when he finds out that Katie has gone through his phone?
"He's really surprised about it but he's also absolutely furious that she's meddling in his affairs. To take somebody's phone out of their pocket and do something like that is nasty and I think it really rubs Robert up the wrong way.
"After what happened at the wedding, Katie has a vendetta against Robert that she's never going to let go. She's really got it in for him. Robert has also got this long-term feud with Andy and Katie. Maybe he's jealous of what they have, with their childhood relationship that blossomed."
Why do Katie and Chas think Robert is seeing Alicia?
"When Katie finds the phone, she sees that the contact he's been exchanging flirtatious messages with is listed as 'A'. Coincidentally she sees Robert chatting to Alicia, who's working behind the bar at The Woolpack filling in a shift for someone. There's a bit of flirting and Katie misconstrues the situation.
"Robert is very manipulative and as soon as Aaron warns him that Katie thinks he's having an affair with Alicia, he really runs with that and has a lot of fun with it. He uses Alicia to make Katie believe that he really is having that affair, just so he can absolutely humiliate her!"

Robert's plan begins to work
Does Robert manage to humiliate Katie?
"He gets to do it in a very public place – in The Woolpack of course! He sends lots of signals to Katie by flirting with Alicia and it's all for her benefit. It does all come out, but you'll just have to wait and see how."
What kind of consequences do you expect if the truth comes out about Robert and Aaron?
"It would be absolutely disastrous because it would absolutely shatter Robert's world. He's come back with all of this status and he's the king of the castle, so that would all be taken away from him and his world would just crumble down.
"More importantly, Robert really loves Chrissie and he wouldn't want to hurt her in that way. He thinks it's fine to have a bit on the side and what Chrissie doesn't know won't hurt her."
Is Robert aware of how much Aaron is falling for him?
"I don't believe Robert is that observant or caring of people who he might see as being peripheral to his universe! I don't think he really sees their emotions as being that important to him. He possibly sees them as being a bit expendable."
What did you think when Emmerdale's producer Kate Oates told you about the story?
"To play someone who is so devious is so much fun. You don't get to be nasty in normal life without any consequences, but I get to do that here!
"More importantly, Robert's particular storyline over this period of time is absolutely brilliant. He's come in with so much history and he has this impending wedding to Chrissie after falling for someone else. He also has the secret of his bisexuality to hide from everyone. I thought all of that was going to be really exciting and I think it's going well."
Have you had any reaction from fans?
"I'm not on Twitter as I'm quite a private person. A few people have asked for pictures and whatnot and that's great. Everyone's been very pleasant!"
