When Nigel ignores her messages, a furious Cathy leaves Alex in charge of the café and storms out. Roy finds the café in chaos with Alex yelping in agony, having scalded his arm, and takes him to A&E.

Later at Nigel's house, Cathy bangs on the window, demanding the truth about Alex. As Cathy sits outside his house refusing to budge, Nigel caves and invites her inside. Cathy asks Nigel outright if Alex is his son. Will she get the answer she fears? Imagine her surprise when he reveals the real identity of Alex’s father to be Eileen Grimshaw.

Meanwhile, Alya tells Sonia that she's outstayed her welcome at Number 6, but Sonia is shocked by her bluntness. When Sonia reveals that Alya seems to be onto them, Sharif decides it's time she moved out. Sensing his panic, a devious Sonia suggests he buys one of Phelan's flats for her.

Later, Sharif confronts Alya about her outburst. Alya is unrepentant, telling her granddad that Sonia clearly fancies him. Sharif's unnerved by how near she is to the truth and agrees to convince Yasmeen that buying a flat is a sound investment for them - and Sonia can rent somewhere else while it's being built.

Elsewhere, Aidan is impressed when Alya and Sinead excitedly outline their bespoke design ideas, but Johnny will take more convincing. Alya and Sinead are then more than a touch confused by Aidan insisting on modelling their ladies underwear designs himself at a local fashion show.

Also, Erica takes charge of Aldi and Asda for the day as Mary is busy at the florist's, but they vow to get Mary back when Erica is too strict.

Finally, Freddie is disappointed when Audrey turns down his invitation to lunch. He drowns his sorrows in the Rovers, and then heads round Leanne’s for an hour at a reduced pensioners rate.

With the truth about Alex's paternity now out in the open, Cathy is in shock as Nigel explains how he found out he isn't Alex's father. He apologises to Cathy for keeping her in the dark and for being a bad actor.

Back at the cafe, Roy returns with Alex. Baffled by Cathy's mood, he demands to know why she walked out. As Cathy explains all to Roy, his calm approach doesn't help and she blasts Roy for his lack of understanding. As she storms upstairs, Roy feels like a stranger in his own home and glances sadly at a photo of Hayley.

Meanwhile, Yasmeen and Sharif inform Alya of their plan to invest in a flat and rent it to Sonia. Alya sneers at Sonia's manipulation and Yasmeen is confused by her rudeness.

When Alya refuses to drop her suspicions, Sharif lies and claims that he slept with Sonia once, years ago. A stunned Alya works out that Sharif is buying Sonia's silence by setting her up in a flat. Sharif admits it, but insists he loves Yasmeen and begs Alya not to betray his secret. Will she agree to keep quiet?

Elsewhere, when Alya's vintage designs impress a client, Aidan offers Alya and Sinead a £60 bonus each. Sinead is pleased but Alya furiously accuses Aidan of ripping him off, and of dressing like he’s in a Showaddywaddy tribute band.

Also, Freddie calls at the salon on his mobility scooter and asks Audrey to join him for a romantic country pub lunch.

Finally, Dev tells Mary that she's breaking the terms of her contract by letting Erica cover her duties.

Imagine her surprise when he reveals the real identity of Alex’s father to be Eileen Grimshaw.
