David is appalled after learning that Audrey (Sue Nicholls) has reunited with conman Lewis Archer (Nigel Havers), especially when she announces plans to go on a round-the-world cruise with him.
Needing funds to finance the trip, Audrey asks David to sign the salon back over to her, as all of her savings are tied up in the business. However, David immediately refuses - insisting that it's for Audrey's own good.
Digital Spy recently caught up with Jack P Shepherd, who plays David, to hear about the bitter family feud sparked by his character's decision.
How do David and Gail find out about Audrey's reunion with Lewis?
"It all starts when Audrey phones up the salon, telling David that she can't come in that day as she's not very well. David promises to hold the fort and doesn't think anything of it, but Audrey is actually fine - she's just hoping to spend the day with Lewis!
"When David tells Gail that Audrey isn't well, Gail suggests that they should go round to see her. David doesn't really want to, but Gail thinks they should take her up some chicken soup and grapes to make her feel better. So David is forced into going, and they visit Audrey's house on Grasmere Drive…"
"When David and Gail get there, they see Lewis coming out of the house - he kisses Audrey and goes off for a takeaway! So David and Gail go into Audrey's house and have a bit of fun with the situation. They keep asking Audrey how she's feeling, knowing full well that she's obviously lying!
"Audrey wants to get rid of them before Lewis comes back, but they insist on making her some soup. Lo and behold, they're all sitting eating dinner at the table when Lewis walks in, so Audrey's really embarrassed that they've found out her little game!"
Are David and Gail angry with Audrey?
"Well, they start complaining to her, saying that she's out of her mind to take Lewis back. They're convinced that Lewis is going to take every penny Audrey has, and they can't believe that she'd be so blind.
"But Audrey shouts back at them, saying that they just don't want her to be happy and are jealous of her being in love. She kicks them out of her house, and throws their coats into their faces. So that's how we find out that Lewis is back on the scene!"
This all leads up to a big battle over the salon…
"Yeah, Audrey comes to David and asks him to sign the salon back over to her, so that she has the finances for a round-the-world cruise with Lewis. David's really against the idea, and so is Gail.
"Kylie also has strong feelings on the matter - she fears that as soon as David hands the salon back to Audrey, then her inheritance will be gone. So Kylie's dead against the idea for money reasons, and she's acting like Lady Macbeth in this whole storyline, whispering in David's ear all the time.
"But it's not so much about the money for David - he just doesn't want his gran to get stitched over by the conman."
"Audrey tears up the agreement which says that David owns the business, and she also changes the locks on the salon and fires him! So David consults a solicitor, who says that what Audrey has done is quite harsh and she has no right to do it, as legally it's David's salon.
"David gives Audrey a letter from his solicitor, but then she rips that up too. It all escalates from there, and David even gets Audrey arrested later on in the storyline!"
Why is David so reluctant to give Lewis the benefit of the doubt?
"David just thinks, 'Once a conman, always a conman'. Lewis has done this with other women in the past, even though he didn't technically do it to Audrey last time round. Because Lewis has this history of fooling older women and getting them to fall in love with him, David and Gail don't even consider giving him a second chance. As far as they're concerned, he's the devil!"
Has it been nice to play scenes with David and Gail on the same side for once?
"Yeah, usually they'd both be at each other's throats! This time it's nice to have the roles reversed, with David and Gail teaming up. There are also some funny moments on the way, so it's not all shouting and screaming. In typical Platt style, there is quite a lot of comedy in this storyline as well."
"Well, there's actually a line in the script where Audrey says that David is the most stubborn person she's ever met. But David says, 'I wonder where I got that from?' They're both really strong-willed characters, but David's not backing down yet. I think it'd take a lot for him to back down, especially as it's his salon that's in question."
What does Nick think about the feud?
"Nick is on Audrey's side. He just thinks that it's Audrey's money, she's earned it, so she should be allowed to spend it however she likes. David's argument is that she won't have a chance to spend it as long as a conman is around, but Nick reckons they should just let Audrey get on with it and trust her judgement."
Whose side do you think the viewers will be on?
"I would imagine they'd be on Audrey's side. I'm expecting people to say, 'What are you doing to your gran? Just let her be happy!' But if people come up to me and say that, I'll just explain David's point of view to them, and I won't let them go for about an hour! I'll try to really get it through their heads that Lewis is a bad guy and he will leave Audrey heartbroken.
"We don't know what's going to happen, but I reckon the viewers will be thanking me in the end!"
"Yeah, I actually did a scene the other day where David's evil eye stare came back. I thought that was nice to see, and some of the crew were saying the same!
"We haven't seen for it for a few years, because David's been loved-up with quite a few romances. Now that he's tied up with Kylie, he's grown up a bit and he's not really into causing mischief or being a prat anymore."
Will David and Kylie stay on good terms in the weeks ahead?
"At the moment, they seem to be getting on fine. I think as long as David agrees with Kylie that he should be going after the salon and not let Audrey take it away, they'll both be on the same wavelength.
"I think it's when David starts getting ideas of his own that the relationship starts to hit a rocky patch! Kylie very much wears the trousers in the relationship…"
