Big Mo (played by Laila Morse) confessed she was in dire need of money, so tried to get some funds together all in aid of Kat’s (Jessie Wallace) “death”.
It was good news for EastEnders fans as the leopard-print-wearing favourite was alive and well and arrived just in time for the charitable event.
Mo was forced to confess she owed a mysterious man £5,000 and was on the run from his mafia-style family.
The newly-reunited Slater family got the shock of their lives when his daughter, Annie, arrived to get the money for her dad.
At the time, Mo pretended to be dead in an extremely desperate attempt to squirm her way out of the debt.
It seemed to be going well until Kat, who couldn’t face seeing her beloved “Nan” threatened, promised to pay every penny back.
Annie generously gave the feisty females a week to pay off Mo’s enormous loan, but with the fundraiser cancelled, where will they find the money?
In new spoiler pictures for next week’s episodes, Annie didn’t wait long before returning to Albert Square.
The blonde bombshell rocks up at the market, desperate to get any information she can on the Slater family.
She lands upon Martin (James Bye) and grills him to give her any gossip.
Not realising who she is, the hapless stall owner accidentally reveals Mo is alive and well, seemingly landing the Slaters in a big heap of trouble.
How will Annie react when she discovers the truth?
Friday’s instalment was a particularly eventful one as Stacey’s shock bombshell left EastEnders’ fans reeling.
After discovering Kat was actually alive, she tore into Mo for lying to her.
It seemed Martin was also a victim of the hoax, as Stacey confessed she only got back with him out of “grief” and he would be devastated to learn the truth.
EastEnders continues tomorrow on BBC One at 8pm.
