When Doug's parents arrive in the village unexpectedly in the coming days, Leanne pretends to be his fiancée as he is struggling to be honest about his sexuality.
Doug (PJ Brennan) later decides that the deception has to end, but when talk turns to his wedding inheritance, it seems that there could be a financial incentive to keeping the charade going…
Digital Spy recently caught up with Jessica Forrest, who plays Leanne, to hear more about the storyline.
How does Leanne get involved in the story with Doug's parents?
"It starts during a party at the lads' pad, which Leanne has planned to cheer Texas and Ste up. Doug's mum and dad arrive unexpectedly, so it's a complete surprise for everyone. Then it turns out that Doug's been telling his parents that he's got a girlfriend, so his mum wants to know who she is!
"After that, Leanne just gets roped into it and it's mentioned that she and Doug will be getting married. As soon as wedding bells are mentioned, Leanne is just going crazy, because she loves a good wedding! So she's dragged into it, but I think she's in too deep and she doesn't really understand what she's signed up for."
What motivates them to go ahead with the fake wedding idea?
"Doug and Ste really need the money, so they're going ahead with it because Doug will get a wedding inheritance once he's married. With Leanne, it's not that she's being mischievous - she just gets carried away with this idea of a big wedding. It's her dream to get married, so she just goes along with the idea!
"You'll see that Leanne's in her own little world, and she doesn't really take the money into consideration. When the money's mentioned, she actually gets quite upset about it and says, 'How dare you bribe me?' But when Doug finally gets down on one knee and does it the proper way, she says, 'Of course I'll marry you - why wouldn't I?' So it's a bit bonkers, as it often is with Leanne!"
What does Ste make of the situation?
"Well, it's Ste's idea! He points out to Doug that they could really do with this money, because they're skint. At the same time, though, Ste is still very reluctant about it and he wants his boyfriend back. Bridezilla's on the scene and she's killing every romantic moment that they have.
"I don't think Ste realised how big the wedding was going to be. So even though it's his idea, there are a lot of scenes where it's obvious that he's jealous."
Do Texas and Dennis get involved in the story too?
"They do, as they're all really good friends, and Dennis has a huge soft spot for Leanne. Texas is only involved a little bit, but she's going to be one of the guests at the wedding. There are more scenes with Dennis, because he's quite jealous of Doug's position due to his own feelings for Leanne. So it's quite funny, as Ste is jealous of Leanne, and Dennis is jealous of Doug!"
As you're friends with PJ in real life, is it strange to film fake couple scenes with him?
"It's really fun, actually! PJ and Bianca [Henrickse-Spendlove] are my best friends, so the story has been a good laugh. I used to live with PJ as well, so it's hilarious."
Leanne doesn't seem so bitchy and scheming lately. Have you enjoyed exploring a different side of her character?
"100% yes - it's brilliant. When Leanne first started in the show, there was a good 12 months of her just being jealous, insecure, immature, naïve, young, and a bit of a bitch. But now she seems to have changed a little bit, although not too much!
"I feel like the character is so nice to play as a single girl, rather than her just being so obsessed with men all the time. I think it's definitely given Leanne more depth to see her going down her own path. We've been exploring Leanne in her own right now that Lee isn't around."
Do you think there's any chance Leanne and Dennis would ever get together?
"I'm not sure, as Leanne is quite shallow so she tends to always focus on the latest hottie on the scene, and be all over him! But I think Leanne and Dennis have got such a good friendship, so who knows? I think sometimes Leanne looks at Dennis and thinks, 'You're so lovely and I know that you'd do anything for me'.
"At the moment, she doesn't fancy him, but there's always lines where Texas will give her a little push by suggesting she should consider going out with Dennis. Leanne says they're just friends, but maybe that could be a cover-up. I'm not quite sure where it could go."
Ashley Slanina-Davies, who played Amy Barnes, recently bowed out from Hollyoaks. Were you sad to see her go after working closely with her last year?
"Really sad! Ashley's such a lovely girl - she wouldn't harm a fly and she's just the nicest person. Because of that, and with Amy being such a loveable character too, it was quite difficult to come into the show and play a character who completely slated her and was always being mean to her! Obviously the audience were always going to say, 'Leave our Amy Barnes alone!'
"When we were filming those scenes last year, me and Ashley would have a little cuddle in between takes and say, 'I love you really!' It was also nice that I was in the final scene that Ashley filmed for the show on her last day."
Who would you like Leanne to share more screen time with?
"Well, I always think that Leanne and Barney work really well together - we had so much fun on the 'Chasing Rainbows' episode. It'd be nice to work with anyone, because everyone in the cast is lovely and it's always nice to see scenes between characters who don't usually interact. It can spark so many ideas, and both the audience and writers see a different side to the characters. It's quite refreshing to work with new people sometimes."
Are you staying around on the show for the foreseeable future?
"I hope so, because I think Leanne's a good character. She is a character and that's what I like about her. People form an opinion on her, whether they like her or they hate her, and I think there's always a lot of scope with characters like that. I love the show and everyone who works here - it's a really good place to work."
