The Happy Valley finale airs on Sunday night and one character set to play a crucial role in how things pan out is young Ryan Cawood.
Right from series one, the now teenager has been at the forefront of the drama as the grandson of Catherine Cawood and the son of the thorn in her side, villain Tommy Lee Royce, who raped and impregnated Ryan's late mother Becky.
Catherine's constant mission to keep Ryan away from Tommy suffered a blow in series two when a woman who became obsessed with Tommy and went to visit him behind bars, posed as a teaching assistant in a bid to get closer to Ryan, spark his curiosity about his dad and try and drive a wedge between him and Catherine.
