A lfie has spent the past couple of weeks convinced that Kat has restarted her affair, but apart from catching her out in a couple of strange little lies, he hasn't been able to prove it – until now.
Believing her husband is away for the night, Kat heads to the bedsit, but it isn't her lover who arrives – it's Alfie. Despite the fact that she's surrounded by candles and rose petals, Kat insists she's only there to tell her mystery lover it's over. However, Alfie isn't going to be fobbed off that easily, especially when he realises that the key Roxy found in the bar, together with the location of the bedsit and the returned ring all point to her lover being a local.
Kat refuses to give a name, trying instead to desperately convince him that she hasn't cheated on him since he first found out about the affair. Then Alfie spots the tenancy document addressed to Mr Branning...
