Stacey Slater is thrilled to see Big Mo back on the Square next week - but her joy turns to horror when she learns that Kat is dead.
We've been waiting for the Slaters to be reunited for months - ever since the news that Laila Morse, Jessie Wallace and Gillian Wright would be reprising their roles as Big Mo, Kat and Jean Slater, fans have been guessing how the famous family would come back.
But the wait is over.
But when Big Mo reveals that Kat isn't with her because she has died - could this mean Jessie Wallace isn't returning at all? Or is it just another of Big Mo's outlandish claims?
Stacey is miffed when she realises she has missed calls on her phone from Big Mo on Friday 16th March - but it isn't until she gets home and comes face-to-face with the lady herself that she realises something is wrong.
But what will Stacey make of the news that Kat is dead? Will she believe Big Mo?
We're not sure we do!
And with Jean also set to make a return to Walford this spring, it looks like Stacey could have some back up in her fight with Martin over the kids.
With their marriage turning nasty ever since Stacey slept with Max at Christmas, the couple have been clashing left, right and centre.
We now know that Hayley is also a Slater - and with her added to the mix, we don't fancy Martin's chances against that formidable lot!
EastEnders airs Monday and Friday at 8pm and Tuesday and Thursday at 7.30pm on BBC One.
