[8] Emmerdale Live aired on 17 October 2012, in the middle of the 40th anniversary week, with the death revealed to be Carl King's.
A new opening sequence was used, consisting of an aerial view of the church, zooming in to Carl King (Tom Lister) sitting alone on the grass with dried blood covering his face; Chas (Lucy Pargeter) and Dan Spencer (Liam Fox) preparing to sign the marriage forms; Declan Macey (Jason Merrells) and Katie Sugden (Sammy Winward) arriving at their wedding reception; Carl's bruised brother Jimmy (Nick Miles) walking across a bridge in distress following their showdown in the previous episode; Cameron Murray (Dominic Power) looking out his bedroom window; Gennie Walker (Sian Reese-Williams) going into labour; Debbie Dingle (Charley Webb) getting loaded into the back of an ambulance; and a high-up view of the village.
Chas is keen to get in the camper van and leave, but Dan announces that he has planned a surprise wedding reception for her.
A panicked Chas makes a quick excuse to leave the wedding reception and rushes to the pub in an attempt to calm herself.
Nicola runs into a bloody Jimmy but he yells at her and walks off claiming he doesn't want to talk.
Katie tells Megan that Robbie Lawson (Jamie Shelton) knew about their scam.
With Gennie about to give birth, Nikhil Sharma (Rik Makarem) ends the wedding reception, clearing people out of the B&B.
As the baby arrives, Rhona Goskirk (Zoe Henry) catches it as Nikhil faints.
As the two grapple outside, Chas becomes horrified when Carl finally reveals that he himself killed his father Tom King (Ken Farrington); ranting that he did it for her and he won't let her walk away from him again.
Diane gets off the phone with Debbie and tells Ashley that they've decided to call the baby boy Jack Sugden.
Cameron is stunned to find Carl is dead and picks up his phone before fleeing the scene.
Mulhern interviewed cast members and "super-fans", as well as answering questions that the public had submitted via Facebook and Twitter during the episode.
