On Monday, as Syed tries to paint over the ‘Bad Boy’ graffiti on the front door, Zainab panics him when she reveals that she knows who the bad boy of the family is – it’s Tamwar and she’ll be able to prove it “before the day’s out”.

Presuming the vandalism was for his benefit, Syed rushes to the café in search of Christian, but, unable to find him, Syed receives a call from Zainab who’s worrying about Tamwar’s whereabouts. Syed soon finds Tamwar looking at his phone, but when asked what he’s looking at, he refuses to show his brother.

Having found Tamwar, Syed tracks down Christian to his flat and expresses his concern that someone knows about their secret affair. Christian, however, tries to allay his fears.

Returning home, Syed finds Zainab spying on Tamwar, and when they barge into the room, they find Tamwar watching something on his laptop. With that, Zainab orders Syed to get Masood. With the family gathered, they discover what Tamwar’s been doing; running an impressions website – www.rudemasood.co.uk – on which he mocks the locals, including Pat, Peggy, Patrick and Dot.

When Masood points out that the impersonations don’t make Tamwar a “bad boy”, Zainab’s concern turns to her husband. Syed tries to talk to his father about the graffiti, but Masood’s convinced that Syed’s been the “bad boy”. After a trip to see Christian, Syed decides to clear the air with his father.

On his arrival at the Masala Queen unit, Syed overhears Masood arranging a trip to the cinema with Jane. Keen to avoid any finger pointing, Syed returns home and tells Zainab that Masood’s definitely the bad boy…

Meanwhile, Jean finds a concerned Stacey watching Ryan’s every move out of the window. Jean tries to assure Stacey that Ryan probably just fancies her, so an increasingly erratic Stacey then tries to help Ryan sell his stock on her old market stall. At that moment, Stacey sees a dark-haired little girl in the market and gives chase, but the girl disappears…

With Bradley’s help, Stacey manages to get her job back on the stall. All’s going well until Stacey spots the little girl again, and when she loses focus, a customer runs off without paying for their goods. Frustrated by Ryan’s anger, Stacey tells him to stick his job, before running off home. Meanwhile, Jean assures Bradley that she’ll tell Stacey about the divorce.

Elsewhere, Sam realises that she needs a job when Peggy gives her £100 and tells her that it’s to last her all week. Ronnie, meanwhile, is becoming frustrated by Sam’s continual criticism of her but Sam silences Ronnie when she reveals her knowledge of her pregnancy plot.

Also, Max receives a stack of bills and final demands and work’s worryingly slow, so he isn’t happy to hear that Tanya’s suggested they all go to see Bradley in Canada for Christmas.

On Tuesday, a desperate Syd’s trying to find someone to look after her dog, Sugar, while they’re in Canada. Seeing her angst, Bradley promises to find Sugar a new home and resolves to tell Stacey about the divorce. Bradley goes to see Stacey but she’s dismissive of his arrival and suggests that he should go and pack, but she also offers to look after Sugar.

While working on the stall, Stacey’s erratic behaviour intensifies again and she tries to attack Ryan, and says that she’ll soon have a big dog to protect her from him. Charlie’s later concerned when Stacey mentions that she plans to look after Syd’s dog and Bradley arranges ‘bon voyage’ drinks in the Vic.

Later, Bradley goes to Max and Tanya’s house and asks Abi if she’ll look after Sugar while he’s at the pub for the farewell drinks and also long-term while he and Syd are in Canada. Abi excitedly accepts, but Max isn’t impressed. Bradley confronts his father, insisting that he’s never been supportive of him and with that, Max relents.

Soon after, Bradley breaks the news to an upset Stacey that she can’t have Sugar. While Jean assures Bradley that she’ll tell Stacey about the divorce, Stacey’s rifling through Ryan’s jacket in the launderette. When Archie walks in, he grabs her violently and says “I’m going to tell ‘em about you”. A shaken Stacey returns home and Jean’s alarmed by her behaviour as Stacey sits on her bed mumbling “he’s going to kill me.”

Meanwhile, Zainab and Masood attend the hospital for a baby scan, but Zainab’s in a foul mood. On their return to the Square, Masood shows off the scan picture, but a furious Zainab – convinced he’s having an affair – exclaims that Masood and Jane are “carrying on” behind everyone’s backs. Jane’s gobsmacked by the accusation while Masood’s incredulous that his wife could think such a thing.

Zainab goes on to reveal that Syed heard them arranging a trip to the cinema. An argument between Zainab and Masood ensues before she has a heart-to-heart with Jane, who makes it clear that she and Masood are just good friends. Concerned that she and Masood don’t do more as a couple, she apologises to him, but Masood questions their marriage, telling her that if they don’t have trust, do they even have a relationship?

Elsewhere, Archie watches a disturbed Stacey in the café and Sam sees an advert for a dance contest.

Back at the Vic, Ronnie asks Roxy why she told Peggy about her attempts to become pregnant and later, Ronnie tells Peggy that she thinks she is in fact pregnant. Excited by the news, Peggy tells an incredulous Sam that she’ll be buying only healthy food from now on in order to help Ronnie with her pregnancy. However, Sam cheers up later when she manages to get Phil to agree to give Ricky his job back at the Arches.

And finally, Bradley tells Syd that he’s glad to be leaving Walford.

On Thursday, an anxious Stacey stares out of her bedroom window and sees the same young girl in the Square that she’s been seeing all week, and when their eyes meet, Stacey backs away from the window. Jean enters the room to give Stacey her pill and attempts to convince her to attend Bradley’s leaving party, but Stacey insists that she doesn’t care about his departure.

With Jean out of the room, Stacey spits out the pill and places it with the rest in the back of her wedding album. When Tanya and the girls leave for the party, Max claims that he has “better things” to be doing. Later, Tanya returns and asks Max why he didn’t want to go, prompting him to admit his belief that he’ll never be able to make it up to his son for his past mistakes. Tanya points out that Bradley will never forgive him if he doesn’t say goodbye.

Over at the Vic, Bradley’s talking to his mother Rachel, who’s revelling in the fact that Max hasn’t shown up to his own son’s leaving drinks. It’s not long before Tanya returns to the party with Max, who immediately takes Bradley to one side and profusely apologises for everything he’s ever done to hurt him and admits that it’ll be sad to see him leave. Max tells Bradley that he’s never hurt him, but he reminds him about Stacey. At that moment, Bradley says that he wants to see Stacey for one last time.

Meanwhile, Rachel and Tanya come to blows over Max in the toilets, but Tanya gains the upper hand when she reminds her that everyone’s moved on apart from her.

Over at the Slaters’, Stacey’s watching the television with no lights on when the doorbell rings. Max shouts through the letterbox and a petrified Stacey cagily makes her way into the hall. With that, she quickly opens the door and drags Max inside, slams the door and frantically bolts it again. Stacey asks if he saw a little girl outside, but Max explains that he’s there to ask if she’ll see Bradley for one last time before he leaves for Canada…

On hearing a strange noise, Stacey declines his invitation before pushing him out of the door again. Max protests that Bradley loves her, but Stacey seemingly doesn’t care and bolts the door again. However, after some thought, Stacey gets ready and decides to go to the Vic after all. A shadow of her former self, a hazed Stacey walks into the bar. Rachel starts talking to her but when she sees Bradley, she says goodbye and good luck.

Stacey then sees Ryan, who asks for his belongings back, but Stacey reveals that she knows he and Syd are trying to drug her. Hurrying away from Ryan, Stacey bumps into Archie and swiftly accuses him of trying to hurt Peggy in the same way he hurt Danielle. Stacey rushes to the toilets and Archie follows, and on seeing him, Stacey smashes a glass and threatens to cut his face. Stacey darts past him back into the bar and cuts his hand on the way.

Everyone stares at Stacey as she proclaims that Ryan and Syd are in league and attempting to drug her, before accusing Archie of trying to attack her. Jean tries to calm her daughter down, but Stacey claims that her mum’s also working against her.

Dropping the glass, Stacey rushes out of the Vic and Jean follows. Outside, Jean tries to calm her down while Stacey screams that she’s not taken her medicine in weeks. Stacey runs home and threatens to run away if anyone tries to stop her. With that, Jean rushes to Dr Al for help…

Elsewhere, a shock revelation stuns Ronnie to the core and Roxy finds Sam with a leaflet that reads ‘Wanted: Topless Models’.

On Friday, Stacey’s a woman on the edge as she shakes and cries hysterically. Frustrated by the flickering lights, Stacey switches off the electricity in the house and sits alone, chanting, “please, please, leave me alone”.

A devastated Jean, meanwhile, is at the surgery with Dr Al, claiming that Stacey needs to be sectioned. Dr Al suggests that Jean go home to be with Stacey while he arranges for a medical team to collect her. At the Vic, Bradley’s consumed with worries about Stacey’s deteriorating health, but everyone assures him that she’ll be fine and suggests that he and Syd still leave for Canada. Jean meanwhile returns home to a pitch-black house and Stacey, sobbing in the living room.

After Jean turns the lights on, the phone rings and Stacey urges her not to answer. She does though and Dr Al informs Jean that the medical team will be there within the hour. Having seen Stacey’s increasingly volatile condition, Jean urges him to hurry them along as Stacey’s clearly unstable.

Heading upstairs, Jean finds Stacey packing her belongings in her bedroom. She tries to assure her daughter that new medication will solve her problems and with that, Stacey reaches for her wedding album and reveals the pills she’s been stashing for the last few weeks. Stacey begins taking them one by one and Jean frantically tells her to stop before dragging Stacey to the bathroom to be sick. Reaching breaking point, Jean slaps Stacey and demands that she listen.

With that, Stacey slumps over the toilet and vomits up the pills. Jean hugs her daughter tightly while Stacey explains that she wants to deal with her illness on her own. Stacey reveals that she’s been “seeing” people, including her late father Brian. With a photo of Bradley in hand, Stacey asks if he’s left for his new life yet, before admitting that Bradley was the only person she ever loved – and she believes that he now hates her.

Deciding that she wants to see him, Stacey heads out to Dot’s house. Barging inside, she finds Bradley and Syd readying themselves to leave for their new life in Canada. In desperation, Stacey frantically apologises and insists that she loves him. Syd tries to cut in but Stacey continues and admits to Bradley that she’s been having visions of their daughter.

At that moment, the taxi arrives to take Bradley and Syd to the airport. While Stacey begs Bradley to stay and hear her out, Syd demands that Stacey let them leave. Stacey protests that nobody can stop her from talking to her husband, causing Syd to scream that she and Bradley are no longer married. Bradley’s forced to agree and reveals that the final paperwork came through three weeks ago.

Bradley tries to leave and when Stacey begs him to stay, he tells her to go away and leave him alone. Bolting home, Stacey runs in on Jean with Dr Al, the medical team, a psychiatrist and a policeman. Stacey instinctively grabs a lamp and throws it at the policeman.

Running into the Square, the policeman tries to restrain Stacey. She spots Bradley across the street and shouts that she loves him. Witnessing the commotion, Bradley rushes over, but Syd says that they must leave. Seeing Stacey’s turmoil, Bradley shouts at the police officers to stop hurting her. However, Syd drags Bradley away while Stacey begs Jean not to let them take her away…

Elsewhere, Ronnie deals with the aftermath of the shocking revelation.
