Tonight’s episode of Emmerdale saw a mystery figure standing guard over the lake where three people had died this week and Nate Robinson currently lies dead and decomposing.

Amy discovered Nate’s body as she fell through the ice while escaping the aftermath of a devastating limo crash which had already killed Suzy. Along with Leyla, Amy later died in hospital – but not before suffering visions of what she’d seen under the ice.

Who was standing watch at the lake on Emmerdale tonight?

There she’d encountered the body of Nate Robinson, wrapped up in plastic and still wearing one of Frankie’s hand-made friendship bracelets. Who killed Nate and how he came to be in the lake remains to be seen, but one thing’s clear… there’s a killer on the loose.

And that killer appeared to revisit the scene of the crime tonight, as a hooded figure stood watch over the lake from deep within the woods. But who was standing at the lake tonight?

John Sugden

Of all the names currently in the frame for killing Nate, John is going to be highest on everyone’s list. The composed military man raised suspicions with viewers for his eagerness and competency in covering up a murder, and many believe that Anthony was far from his first.

Add to that the mounting evidence (the way Nate’s body has been disposed of seems awfully familiar), and viewers are convinced that Emmerdale has a serial killer on its hands. Could John Sugden have returned to the scene of the crime tonight to check his handiwork remains hidden?

Caleb

Nate’s uncle Caleb was indirectly responsible for his exit from the village – being the one to tell Cain that he’d spotted Moira snogging Nate in the barn. This misrepresentation of events led to Nate’s beating at the hands of Cain, and his decision to leave.

Many have long held suspicions that Caleb killed Nate, and this week’s events provided little proof otherwise. As the episode ended, Caleb stomped out of the house, clearly up to no good. But where was Caleb going? Did he go straight to the lake to visit Nate?

Cain

Also skulking about the village on mysterious business, Cain was similarly unaccounted for as the episode ended. Finding him full of self-loathing in the pub, Chas entreated Cain to get over himself and make amends with Moira. Instead, he huffed off, on business unknown.

While it’s unlikely Cain killed his son, his whereabouts were unknown as the episode ended.

Did Jacob visit the lake in Emmerdale tonight?

There’s also the possibility that the lake’s mystery visitor may not be related to Nate at all. A tormented Jacob, perhaps, paying visit to the site where his mum died?
