Who will die in Emmerdale this week?
Soap bosses are keeping tight-lipped about who will die this week in the Dales, but it looks like it will be either Moria or Emma.
Natalie, who plays Moira, told Digital Spy: "Moira is frightened as they both could die. It's really dangerous in the barn and Emma is a loose cannon. The barn is full of lots of hay and straw bales, plus oil drums, farm machinery and diesel supplies.
"But the most frightening thing in the barn is Emma. Forget the fire, it's Emma who is the biggest threat at this point."
She added: "There is much more to come and a few twists we hope you will enjoy. Don't miss it!"
Who else has Emma Barton killed?
This week viewers also saw a return of the ghost of James Barton to haunt Emma.
James was killed by Emma a year ago when she pushed him off the bridge and into oncoming traffic when he escaped from her holding him captive and drugged at his farm.
Show boss Iain MacLeaod decided to bring the character back as his killer Emma began to unravel and confess her crimes to an increasing number of people.
