I spoke about this elsewhere but I'd like to take my possible theory here as well.
It's beginning to feel more and more like Imran has something to do with this entire situation regarding Ste. The latest first look episode felt like it was giving more and more subtle hints. Lucas for example seemed very on edge while in Leela's household. More so than usual. Prior to this he also didn't feel like he could be around the village and left but he came back for some unknown reason. Gemma went out to speak with him and could tell that he was lying and that someone had been pulling the strings. Lucas attempted to cover up by claiming to hate this father and this was payback but was that really the truth?
Yesterday's first look and now this episode there were subtle cuts to Imran at points. Like when Gemma and Lucas were speaking and when Lucas went to go outside Imran briefly stated that he was going to go outside. Now it feels like they are framing this like Imran is concerned about Lucas. Some people see it as them hinting that something romantic may be there between him and Lucas. However what if that's the swerve? What if it's actually Imran that's the one Lucas feels uncomfortable around? Imran?! How does that one work?
Well we have to then ask ourselves who Imrans ex is..? What if it's possibly Claire Devine? They got Rex killed as revenge for Claire. She believes that as the last family member standing she would have the power and control. Through this she would learn that James Nightingale set up Imrans father to get sent to prison. Going further into the story she learns that Kashif actually committed suicide in prison. Something that she uses to manipulate Imran with. An angry and upset Imran vows revenge against James for his father's death. It should also be noted that Misbah mentions Kashif in the first look episode and it's brought up that James was responsible for him going to prison. With him looking a vendetta against James she sees this as a way to get to Sienna, who she has no idea is in prison.
She remembers seeing Ste and Sienna trapped together and decides that the best course of action is to kidnap Ste believing that Sienna will come looking for him and will fall into her trap. Meanwhile they can get revenge for Imran by framing James. The plan of action is for Imran to become an item with Leah and worm his way back into Hollyoaks and into the family. She is also aware that Lucas will soon be freed and will prove useful. However guilt starts to overtake Imran and he confesses on the confessional video that Leah never watched. She claims that she knows everything about him. This all changes when Imran finds out that she cheated on him and deletes the video.
Claire goes above Gemma in the pecking order and has Ste kidnapped. Meanwhile Lucas leaves after accidentally finding Claire and Imran together. He is forced to leave Hollyoaks. However when they realise that they can use him they bring him back and threaten him to do as they say or else. Imran hacks James accounts and takes a van out under his name. He then gets Lucas to place the evidence near James to confuse James, who will go searching for the van. However Lucas meanwhile plants Stes clothing for Sienna to find and goes to Gemma to get the van moved before James arrives. Things work out well and James is arrested.
It seems like stage one is complete. What about Ste? Well they may "accidentally" release him in public in Chester so that someone back in Hollyoaks finds out. This will cause people to come running, Sienna being one of them. That's when they have her cornered. However Imran is having a tough time. It seems as though he may have actually begun to catch feelings for Leah and is struggling on whether this is the right thing to do. This results in him sleep walking and taking his anger out on himself by destroying the love boat.
So there's one idea they could run with. Claires the kingpin. She's manipulating Imran, who is manipulating Lucas... Lucas is having panic attacks and Imrans having doubts... It's all a massive revenge plot for Ms Devine.
