The identity of Kat's mystery Branning man will finally be revealed in a climactic episode airing on Thursday, December 20, leaving Alfie disgusted when he finds out that the guy in question is close to home.
As details of the big reveal are currently being kept firmly under wraps, we can only disclose so much of what the consequences are for Kat (Jessie Wallace) and Alfie (Shane Richie).
However, new pictures show that it doesn't look good for the Moons' future as Alfie completely blanks Kat when they come face-to-face at the local Santa's grotto.
Jean Slater (Gillian Wright) also appears to be aware that Kat has betrayed Alfie, as she is unable to hide how disappointed she is in a picture of the pair outside the Queen Vic.
It's no surprise that Roxy Mitchell will be supporting Alfie through his troubled time, and the pair are seen sharing an intimate moment under the mistletoe in other photos offering a sneak peek at Christmas on Albert Square. Is their romantic spark about to be revisited?
EastEnders continues tomorrow (December 6) at 7.30pm on BBC One.
