Kim is one of many who's out to get Graham, played by Andrew Scarborough, and this week, he will be killed off in a grisly 'whodunnit' storyline.
Speaking to Daily Star Sunday, Claire says: "Kim shows her vulnerable side and admits that she is still in love with Graham.
"They've been together on and off for 20 years, and she lays her heart on the line and tells him. He leads her to believe that they're going to get back together.
"It's all quite cruel really. So when she discovers that she's been played she decides she wants to get rid of him and orders his murder.
"Andrew has created such a unique character and he is so popular with the audience so I don't think I'll be on social media after tomorrow night's episode, they're all going to hate me."
Alongside Kim, the current list of suspects are Jamie Tate, Andrea Tate, Al Chapman, Jai Sharma, Charity Dingle and Marlon Dingle.
I don't think I'll be on social media after tomorrow night's episode, they're all going to hate me.
The storyline will not keep viewers guessing for weeks as the killer will be revealed in a special episode on Friday January 24.
The events leading up to his death are shown from Graham's point of view, finally revealing his killer.
But who has blood on their hands?
Emmerdale airs weeknights at 7pm on ITV, with an extra episode at 8pm on Thursdays.
