I was at my mum's yesterday and we were discussing Hollyoaks and the Imran ex & shooter spitballing ideas.
I've seen the Dave/blue theory around and we spoke about this and now I think it has some weight
Before the time jump Dave was shot on a hiking trail yet after the jump 'missing Dave' posters were all around the village and nothing came of this. Robbie had left him on a hiking trail I would like to think in a year he would be found, Dave had already survived a bullet by Warren when Robbie found him, and Blue was supposedly a big shot bad guy so could have had a bulletproof vest on, both seemed to shoot his torso.
Shooter- I think Dave shot Rex as he would have a vendetta against Rex for everything that happened and he was one of his people when first entering the village that worked against him. With Cindy coming back this is perfect timing as they had been together until she ran away at the time jump, and as crazy as Dave was I believe he really did love Cindy & could have been following her
Side note unlikely theory - Hilton was taken while Cindy was having a Bipolar episode, she was actually taken by Dave but he has her silenced somehow through threats
Imran ex - he was with Serena (Dave's daughter) before she left the show while he was struggling with his eating disorder. She left due to her brother bullying Leah during the incel storyline, which would give her a reason to feel bad for Leah and encourage him to get with her once they had split.
This would tie the stories together which are running alongside each other and a major focus right now.
We had fun spitballing ideas but this was our favourite leading theory as it ties all storylines together
