As the nation awaits the final ever episode of Happy Valley- social media has been flooded with theories about how Sally Wainwright's hit show will end. In a 70-minute long final episode this Sunday, the fates of Detective Catherine Cawood (Sarah Lancashire) and TV's most evil villain Tommy Lee Royce (James Norton) will play out - and some fans are convinced that Catherine's grandson (and Tommy's son) the now teenage Ryan Cawood is going to play a pivotal role.
*SPOILERS AHEAD*
In the penultimate episode, Tommy escaped from court and was on the run, and has plans to head to Spain - but first, he has business to take care of, namely killing Catherine.
Speaking via an online gaming chat, Ryan grilled his dad, repeatedly asking him if he was indeed 'armed and dangerous' as news reports claimed. Tommy then shares his grand plan for a fresh start abroad, saying: 'I've got this chance, to get abroad. And if you wanted, you could come with me. I know a fella who can set us up in Marbella. House, car, money, job.' The episode ended with Tommy asking Ryan to come with him to Marbella, and Ryan supposedly taking time to think about it.
Ryan's conversation with Tommy came after an emotional rant from Ann Gallagher (partner of Ryan's uncle Daniel) - who revealed the extent of Tommy's heinous crimes towards her and Ryan's late mother.
This has lead some fans to believe that Ryan is 'playing' Tommy - and he will set him up, so he can be caught and taken back to jail. Others think Ryan will go further and kill Tommy as revenge for everything he has done.
Some speculate he will have to kill Tommy in order to protect his grandmother. Others think Ryan will kill Tommy but Catherine will go down for it, taking the blame for Ryan.
However it plays out, we're hoping that Ryan finally sees Tommy for what he really is: a dangerous, violent psychopath, and not the caring father Tommy is trying to pose as.
An alternative theory is also emerging online, that Catherine's sister Clare (Siobhan Finneran) will kill Tommy. Or will die in the process of trying to save Catherine.
In the last episode, still furious that Clare and her partner Neil had taken Ryan to see Tommy in prison, laid into Clare, calling her a 'pissed-up, lightweight, empty-headed … noo-noo' leaving poor Clare speechless.
One Twitter user commented: 'Leftfield shout - Clare goes mad and stabs him. After everything Catherine said to her tonight, she finds her spine, kills Tommy and dies in the process somehow.'
Almost all the online theories result in someone's death - which feels pretty much a given at this point. Exactly who and how - well, we're counting down the hours til the finale....
The final ever episode of Happy Valley airs 5 February, 9pm, BBC One
