Emmerdale fans believe they've figured out who will reveal John Sugden's (Oliver Farnworth) lethal actions, and it's not his partner, Aaron Dingle (Danny Miller).

John arrived in the Dales last year, claiming to be the long-lost son of village legend Jackson Sugden (Clive Hornby). He was introduced to his half-sister Victoria Sugden (Isabel Hodgins) and revealed he lived in his van.

Despite a shaky beginning, John began a relationship with Aaron and disclosed his army background. However, viewers quickly grew suspicious of John's darker side after he disposed of Anthony Fox's (Nicholas Day) corpse earlier this year.

On Thursday (April 10), Emmerdale finally confirmed that John is indeed a dangerous man, having killed Nate Robinson (Jurell Carter). It appears John is intentionally putting people at risk so he can rescue them and play the hero, but his scheme goes horribly wrong.

After the fire at Moira Dingle's (Natalie J Robb) barn last year, John saved Nate. But then he injected Nate in the neck with medication, causing him to scream in agony, reports Leeds Live.

Moments later, John was ready to administer another dose of medication to save Nate's life, but it was too late - Nate was already dead.
