Perhaps Alison will end up protecting Catherine from her inevitable showdown with Tommy, who has made clear he is after her.
Still living a somewhat isolated life and no doubt traumatised by what happened with Daryl, perhaps Alison will risk her life to help her friend.
The trailer for the concluding episode, which was released on Tuesday, showed Catherine breaking down in tears in the street.
Could this come after Alison ends up dying at the hands of psychotic killer, Tommy?
Fans will have to wait until Sunday to find out exactly how Alison’s story will end.
Happy Valley concludes on Sunday at 9pm on BBC One.
