As a new day dawns following the Queen Vic fire, the Mitchells are still reeling from the shocking events and it's unclear whether they will ever be able to recover.
However, after considering everything that has happened to her family recently, Peggy ultimately decides that the best thing for all of them is to stand on their own two feet - which means she has to leave.
Before making her departure, a distraught Peggy pays one final visit to The Vic, which is now little more than a shell after being destroyed by the blaze.
Determined for the police not to find out that Phil started the fire, Peggy also visits Stacey - telling her to take the blame for the crime, as her sentence for arson will be less than it would be for Archie's murder.
Facing a new dilemma, what will Stacey do? And how will Albert Square cope without its first lady?
Peggy's final EastEnders episode airs tonight at 8pm on BBC One, and will be followed by EastEnders Revealed - Peggy Mitchell, Queen of The Vic at 8.40pm.
