In episodes of EastEnders which will air on Thursday, September 13 at 7.30pm and Friday, September 14 at 8pm on BBC1, we’re finally going to learn who it is that Kat Moon has been having an affair with!

As will poor old doormat Alfie (Shane Richie) who has been completely oblivious to the fact that Kat (Jessie Wallace) has been playing away, yet again.

So who will Mr X turn out to be? Well, I think it’s Max (Jake Wood) based only on the fact that when Kat was bandaging up her mystery man after the fight in the Vic, the ‘patient’ wore a black shirt, and of all the men who were brawling, only Max wore a black shirt.

But of course, that may have been a red herring, designed to throw us off the scent, and still in the Mr Lover Lover running are Derek, (Jamie Foreman) Jack, (Scott Maslen) and Michael Moon, (Steve John Shepherd) in addition to Max…

However, back to the moment when Alfie learns about the affair, and it all begins when a big bouquet of flowers is delivered the pub for Kat. In addition, before the pub reopened after its fumigation, Kat spent the night with her mystery man, and had to lie about her whereabouts to Alfie.

But he soon becomes suspicious, especially as Kat seems to be overcompensating with him, lavishing affection on him.

So, not really wanting to hear the truth, but feeling like he has to ask, Alfie confronts Kat about her ‘missing’ night and the flowers. Unable to keep her secret any longer, Kat tells Alfie that she’s seeing someone, and adds that she thinks she’s fallen for him.

However, when he demands to know who the man is, Kat lies and says it’s nobody he knows.

As things become more heated, Alfie pushes and pushes to know the man’s name, and when Kat obstinately refuses, he grabs her and slams her against a wall, but of course, this being Alfie, he immediately regrets his actions.

So is this the last straw for Alfie? Are the Moons well and truly over? Find out, as mentioned, on Thursday, September 13 at 7.30pm and Friday, September 14 at 8pm on BBC1.
