EastEnders viewers will see Alfie Moon faced with a terrible dilemma as his wife Kat lies in hospital.
Alfie (Shane Richie) will struggle with his conscience over whether to tell Kat (Jessie Wallace) that he was the reason for the fire at their home, but he will face alienating his family if he does admit the truth.
Kat is in hospital after being injured in a blast from the fire, which was started by Alfie in desperation at their financial problems.
Alfie had thought that Kat was out at a party, and he was panic-stricken when he spoke to her on the phone to find that she had stayed at home and was unable to get back in time to save her.
He is wracked with guilt when he sees her in plaster and lying in a hospital bed, while Stacey Branning (Lacey Turner) and Big Mo Harris (Laila Morse) are devastated at the news of what they believe was an accident.
The scenes will screen on EastEnders tonight (September 18) on BBC One.
