Zainab makes a shock discovery

Billy looks across the Square as DCI Marsden removes the tarpaulin covering the door to The Vic, while Mo moans that the police are dragging their feet in catching Archie's killer. Billy's distinctly unimpressed by Mo's attitude but before he can say anything, he's interrupted by a phone call. Meanwhile, Janine's curious to see Marsden outside The Vic. Later, Marsden calls at Janine's flat and questions why she was out on Christmas Day, before asking Janine about Archie's missing laptop. Billy turns up to see the Mitchells and reveals that he's the executor of Archie's will, prior to revealing that everyone - including Janine - has to be at the reading.

Despite Peggy's offer to cook a family meal, Glenda out-does her as she announces that she's booked a table for them all at Fargo's. Peggy puts on a brave face but when she looks through Glenda's case, she finds something intriguing…

Meanwhile, Zainab's unhappy when Tamwar mentions Christian but her mood is lifted again when she's shown a postcard from Syed and Amira - and she later shows it to Christian out of spite. After Peter deletes a video message from Lauren off his laptop, he quickly regrets it and turns to Tamwar for help in retrieving the file. Later at the book club's anniversary meeting, Zainab turns up even though Jane didn't invite her, and Denise isn't happy that Heather's in attendance. While Denise and Heather continue sniping at each otherabout baby George, Darren and Libby, Jane makes it clear to Zainab in the kitchen that she's hot happy by her attitude towards Syed being gay. When Zainab makes a dig about Jane not having children of her own, Jane flips and throws her out.

Back at home, Zainab walks in on Tamwar listening to something on the Beales' computer. Despite Tamwar's protestations that there's nothing of interest on the laptop, Zainab demands that he play the file. Zainab's gobsmacked to hear sounds of Ian and Janine in bed together.
