When Sinead and Gaz (Joel Goonan) land an exciting chance to head off on a European tour where they'll be selling gig merchandise, they quickly make plans to leave for a fresh start - believing that they don't have anything keeping them in the area.
However, Sinead's big news comes at a cost to lovesick Bart McQueen (Jonny Clarke) as he still has feelings for her but is too stubborn to admit them. With Jason's help, will he declare his love to Sinead before it's too late?
Here, Stephanie Davis - who plays Sinead - chats to Digital Spy about the latest storyline twists ahead for her character.
How strong would you say Sinead's feelings for Gaz are at the moment?
"To be honest, I don't think they're very strong. If anything, I think Sinead feels sorry for him because he's had a hard life. It's a bit like he's the consolation prize for Sinead - she's gone with him to prove a point to Bart, but also because she wants to be happy and she wants to be loved. Because Bart's not fighting for her at the moment, she just thinks 'Why not?' when it comes to Gaz."
Is Gaz's bad boy nature part of the appeal for Sinead too?
"Yeah, I think she is a bit of a fan of bad boys! She really likes the risk of being with someone like that - she enjoys it when she doesn't know what's going to happen next."
Where does that leave things between Bart and Sinead?
"Well, I think you can tell that Sinead actually isn't that happy with Gaz. It seems like Gaz just wants one thing a lot of the time. The main reason Sinead is with Gaz is that she wants Bart to wake up - he can have her if he wants her, but he's just got to fight for her. But she's starting to give up, so that's why she's trying to make things work with Gaz."
What's going on between Gaz and Maddie at the moment?
"Gaz continues to try it on with Maddie. Maddie has told Sinead about this, but she just thinks that Maddie is trying to meddle - as they have this Mean Girls-type relationship where they're both trying to be the most popular and well-liked. Gaz is also playing some mind tricks with Sinead, but he's secretly planning to finish with her because he likes Maddie more."
What happens next?
"Gaz is just about to finish with Sinead, but at that moment, he sees her chatting to a guy who's a tour promoter. They both get offered a job selling gig merchandise on a tour that's going all over Europe.
"When Gaz realises that Sinead has got him this job and really does care for him, he changes his mind and wants to stay with her. So Sinead makes the decision to go away on tour with Gaz and leave Hollyoaks. She feels like she has nothing keeping her in the village, so she might as well try to make a life somewhere else."
Does Sinead tell Diane about her plans?
"She doesn't! Sinead feels like she's caused her mum enough hassle, and she knows that Diane wouldn't take the news very well. So she doesn't tell her - she's planning on just getting up and going."
Do you think there's anything genuine about Sinead and Maddie's friendship?
"I think at the moment it's a case of 'keep your enemy close'. They're friends with each other, but Sinead's a good judge of character and she can see what Maddie's about - even if nobody else can see it. Sinead's quite wary of Maddie, but in this storyline, she's had enough of her by this point and is suspicious of what Maddie's telling her about Gaz."
Jason is the one who's trying to play matchmaker between Bart and Sinead, isn't he?
"Yeah he is, and I think that's really nice. The three of them have been through so much together. Jason realises that nothing will ever happen between him and Bart, as Jason wants to be a boy and that's the end of it. So Jason tells Bart that life's too short and he should go after Sinead before it's too late.
"Sinead is in London with Gaz for a concert and will go on the European dates immediately afterwards. So it's a case of whether Bart will fight for Sinead and whether he'll win her back - or if she'll go away with Gaz and leave Hollyoaks."
Do you think Sinead and Bart are made for each other?
"I think they are, yeah. Even though they have their ups and downs, they know each other so well and they both come from similar broken families. No matter who comes along, I really think that Sinead and Bart are the ones who are meant to be together."
Have you enjoyed showing Sinead in a new surrounding recently as she's now at the sixth form?
"Yeah, I have! It's been a big transition for Sinead and she definitely didn't get off to a good start. But I think that there's a chance she could start to settle down. I think you're going to see a different side to Sinead with some of the stuff that's coming up…"
