Emmerdale fans are speculating Marlon Dingle could be Graham Foster's killer - but he isn't the only one in the frame.
They also suspect his cousin Charity Dingle will help him, and that they might even team up to murder Kim Tate's ex.
Viewers saw the pair discussing Graham after his confession about Noah and the drugs at the hospital.
Noah collapsed and suffered from hypothermia and kidney damage after taking pills and collapsing in the woods.
Graham told Charity how he had seen her son with drugs just days earlier, and now questioned if he had a drug problem.
But Charity was fuming with him, even blaming him for his current condition.
She then warned Marlon about Graham - who is currently dating Marlon's ex Rhona, the mother of his son Leo.
Charity claimed he needed to watch his back, as Graham might take Leo away.
She also said they needed to team up together to look out for each other against "poisonous" Graham.
Judging by the look on Marlon's face, it was clear he thought Charity might be right.
He is yet to find out Graham and Rhona are planning to move to France, and are taking Leo with them.
Fans now think that once he knows, Marlon might kill Graham - and Charity might help him.
One viewer said: "Okay, I am on board with Charity and Marlon killing Graham together... "
Others agreed, thinking a twist was on the cards.
Emmerdale airs weeknights at 7pm on ITV, with an extra episode at 8pm on Thursdays.
