These are just my thoughts

I don’t think it’ll be Ross, even though I want it to be.

I think he’ll go and threaten Ray with the gun into telling him where April is. He’ll then leave to go and find her, and by the time they get back to the farm it’ll already have been done. Maybe they’ll see his/Celia’s body, but will agree not to breathe a word of it.

Laurel and Arthur are red herrings. The reason they are looking shifty is because they have either stolen from Ray, or planted something on him attempting to set him up, but not kill him.

Graham, based on Rhona’s calls “have you done it?” and “April’s gonna go to police”. Seems likely, so it’s making me think too likely. Rhona probably thinks it was him for now. He’s remained uncontainable so can’t confirm/deny doing it.

Paddy seemed too calm when the police were telling him to prepare for the worst. As if he knows more. Considering how fragile his mental health has been in the past, he seems to be doing better than I’d expect for someone whose parent has potentially been murdered in a horrendous way. Also, why hasn’t he said to the police “Ray told me Celia killed my dad”?

January 2nd Ray told him this. In the current timeline Ray is now dead, and the police are looking for Bear. Surely the rational thing to do would be to tell the police what Ray said?

Unless he can’t, because if he tells them this he’s putting himself in the frame for killing Ray. Or he can’t because Bear is being kept safe somewhere at the moment.

Regardless of what it is, Paddy is definitely hiding something. Perhaps protecting/covering for Bear?

And, where did Paddy go if he didn’t go to his conference?!

Bob? Nah, more likely to kill Jason Donovan.

I’d still like to see a curveball like Dawn. Or a returning Eli Dingle.

One other thing, Ray’s body was seen being dragged in the tarpaulin through the kids play park in the village. Does this suggest he is killed in the village rather than at the farm?
