Who Graham Foster is working with to target Kim Tate on Emmerdale may have been rumbled by fans.
While some theories suggest a Dingle or a Tate is involved, other views have recalled a past storyline. It’s led to the theory that in secret, a specific character, who hates Kim, is helping Graham to kill her.
On Monday, we saw Kim rushed to hospital with it thought she had suffered severe mushroom poisoning. The Dingles all accused each other of targeting Kim, from tampered food to dodgy wine being listed as the cause.
Meanwhile, it was later revealed at the hospital that it was linked to medication with Kim worried she had overdone it recently to the point she was becoming forgetful. As those around her suggested she’d accidentally overdosed on painkillers, she was adamant she wouldn’t have.

That’s when we saw Graham messing with her tablets in the cupboard. He’d swapped out her bottle of tablets for a similar one, containing different pills.
As he swapped them back, we heard him on the phone to someone claiming the dose had not killed her. He seemed disappointed, as if the plan had been to kill Kim.
But who was he talking to, and why does this person want Kim dead? Why would Graham work with someone to get rid of Kim? Fans think they’ve worked it all out, and it’s to do with a scene involving Caleb Miligan.
Caleb had met Graham before his arrival to the village a few years back. It’s Graham that told him about his father Frank Tate’s death and Kim’s link, leading to his plan of revenge against Kim.

This was all forgotten about while he clearly still despises her. So Have Caleb and Graham united once more to end Kim for once and for all? While Caleb might be part Tate, he isn’t one as he’s a Miligan and is also part Dingle. One fan said: “Yes he said about poison to Kim before she left home farm I think he’s on phone to Caleb.”
Another said: “Mr robot and the troll Caleb want Kim dead,” as a third added: “Well I was wrong there! Twists and turns always, question is now, who is Graham speaking to on the phone? My gut is saying Caleb.”
It comes amid reports that Kim’s stepdaughter Dawn Taylor will leave the ITV soap later this year. Nothing has been confirmed by the ITV soap yet about if it’s true, or how it will happen. Meanwhile, we have a returning character on the way with Chris Coghill reprising his role as Kev Townsend.
