Anita, 75, last appeared on EastEnders in 1988 as Angie, one of the original soap characters who has been involved in some of the most iconic episodes in EastEnders history.
As Sharon tells her that she's cold, Angie replied: "I know baby and I wish I could just put my arms round you and give you a great big hug but it's not time for us to be together yet darling.".
After becoming trapped upstairs in the pub, Angie's daughter Sharon Watts began to lose consciousness - with the Walford resident hallucinating Angie speaking to her.
"KAT SLATER HAS FINALLY APPEARED #eelive #eastenders," another penned as a third wrote: "Oh finally there’s Kat!!
It follows the shock cameo by legend Anita Dobson who returned to the BBC soap on Wednesday night, reprising her role as the late Angie Watts.
