The new mother (played by Natalie J. Robb) was left fighting for her life when the barn exploded as she gave birth to an unexpected child.
Although Emma (Gillian Kearney) did help to deliver the baby, Moira was left reeling upon learning she killed James Barton (Bill Ward).
While she recovers in hospital, Moira sets about letting the world know exactly what her nemesis is, starting with Faith Dingle (Sally Dexter) and Victoria Sugden (Isabel Hodgins).
However, fans will recall that Emma is currently on the run after kidnapping Moira’s newborn in one of the ITV soap’s most shocking scenes.
Will the past catch up with Emma? Or is more tragedy about to strike Moira?
Elsewhere in Emmerdale, fans are concerned for Finn Barton (Joe Gill) after he suffered a gun shot wound.
Last night’s instalment saw the loveable character’s life support machine flatline, leaving viewers convinced that he is another of Emma’s victims.
Actress Gillian has teased more drama to come from the soap’s big autumn extravaganza.
The 45-year-old hinted: “It’s only just beginning now. It’s the trigger for more mayhem really.”
