The road to the altar is rarely smooth in EastEnders, and for iconic couple Kat Slater and Alfie Moon, it’s a familiar bumpy ride filled with twists, betrayals, and heartbreak. In a shocking storyline set to unfold in the week beginning Monday, June 9, what should have been a new beginning could very well become their final goodbye—again.

Kat and Alfie have long been one of EastEnders’ most beloved and volatile pairings. Their rollercoaster romance first kicked off in 2002 when Alfie was introduced to the square. Viewers watched as Alfie charmingly wooed Kat away from the clutches of gangster Andy Hunter, culminating in a memorable Christmas Day wedding episode. But true to soap tradition, happily-ever-afters are never guaranteed.

Their first marriage didn’t last. It collapsed after Alfie discovered a tape of Kat cheating with Andy, triggering their first major breakup. Despite the betrayal, their story was far from over. They reunited by 2010 and returned to EastEnders after a five-year break—only to face yet more drama.

Kat was pregnant after a brief fling with Alfie’s cousin Michael Moon. Alfie stepped up to raise the child, Tommy, as his own, even through the chaos of the infamous baby swap storyline. But once again, their relationship was tested—this time by Kat’s affair with Derek Branning and Alfie’s marriage to Roxy Mitchell.

Still, the pair managed to find their way back to each other, marrying for the second time in 2014 and welcoming twins Bert and Ernie. Though time and turmoil continued to weigh heavily on them, viewers couldn’t help but root for their resilience.

Fast forward to 2025, and after a recent rekindling of their romance over the past six months, Alfie prepared to propose once more, hoping to seal their third marriage. However, this long-awaited reunion is at risk of crumbling after a deeply hurtful misunderstanding.

In scenes airing on Monday, June 9, Kat stumbles upon a sexually explicit video on Alfie’s laptop. Confused and heartbroken, she begins to believe that Alfie may have turned to adult entertainment—especially since intimacy between them has been lacking following Alfie’s recent battle with cancer. Instead of confronting Alfie directly, she turns to her trusted confidante Jean Slater and confides her growing suspicions.

Alfie, unaware of the storm brewing, tries to surprise Kat with a romantic dinner, but she arrives on edge, expecting to reignite the spark between them. When Alfie gently tries to slow things down, not ready for intimacy yet, Kat interprets it as rejection and storms out, even more hurt than before.

Tuesday, June 10, sees both Kat and Alfie receiving heartfelt advice from Jean and Patrick Trueman respectively. They’re encouraged to open up and address the emotional distance that has crept in. Eventually, the two sit down for a serious, soul-baring talk. It’s during this conversation that the topic of the explicit video surfaces—and Alfie is completely blindsided. He has no idea what Kat is talking about.

As it turns out, the truth behind the video is much darker than Kat initially thought. Her son Tommy had unknowingly come across the content with the help of Joel, a boy being mentored by Ross Marshall. Joel, in an attempt to seem more “grown-up,” had been exposing Tommy to inappropriate material. Vicki Fowler had earlier expressed concern that Joel lacked a positive male influence—and her worries now prove devastatingly valid.

Back in Walford, the big wedding day arrives on Wednesday, June 11, but the celebratory mood is overshadowed by Kat and Alfie’s unease. Their concerns over Tommy, the fallout from the video, and a string of wedding planning mishaps put Kat on edge. She finally admits to Alfie that she’s having serious second thoughts and—just like that—the wedding is called off in dramatic fashion.

Thursday, June 12, picks up the pieces. Alfie is left reeling from the cancelled wedding, questioning whether he and Kat can overcome yet another bump in their long, storied road. As Kat leans on friends Elaine Peacock and Yolande Trueman, the women reflect on their own romantic ups and downs, offering Kat a chance to gain some much-needed perspective.

Meanwhile, Alfie receives an unexpected pep talk that gives him hope—not just about fixing things with Kat, but about being the steady presence Tommy needs in light of recent events.

With so many misunderstandings now laid bare, the real question is whether Kat and Alfie can push through the hurt and confusion, and finally reclaim the love they’ve spent over two decades fighting for. Will the wedding go ahead after all, or is this the final chapter in their saga?

One thing’s for sure—EastEnders fans are in for an emotional week, packed with drama, heartbreak, and the kind of classic soap storytelling that keeps viewers coming back night after night.

Stay tuned to find out if Walford’s most iconic couple get the ending they deserve—or if Kat and Alfie are destined to remain star-crossed lovers forever. 💔
