In one of the most devastating moments Home and Away has ever delivered, Summer Bay will be left shattered next week when Mackenzie Booth’s ongoing emotional struggles reach a tragic and irreversible breaking point — and Levi Fowler is left to witness the unthinkable.

After months of turmoil — battling debt, heartbreak, and the recent collapse of her relationship — Mac (played by Emily Weir) has been walking a fragile line between keeping up appearances and quietly falling apart. Now, in scenes that will air next week, that pressure finally explodes in a devastating act that will leave viewers in shock and the residents of the Bay reeling.

Sources close to the production tell TV Week that the storyline has been handled with “deep care and sensitivity,” but that doesn’t make it any easier to watch. “It’s raw, it’s confronting, and it’s going to break people’s hearts,” an insider reveals. “Emily Weir delivers a performance that’s gut-wrenching. You’ll see a side of Mackenzie that’s truly desperate — and Levi’s reaction is just as powerful.”

The emotional climax begins when Mac, struggling to see a way out of her mounting problems, reaches out to Levi (Tristan Gorey) one last time. The pair, who have shared an intense connection despite the chaos surrounding them, meet at the Pier Apartment late at night. Levi, sensing something’s wrong, pleads with her to open up.

But moments later, tragedy strikes. In a shocking and deeply emotional sequence, Levi realizes too late that Mac has taken drastic action. As he rushes to her side, panic sets in — and the calm, composed doctor completely unravels. “It’s Levi’s worst nightmare,” the insider explains. “He’s used to saving lives, but this is someone he cares about — and in that moment, he’s powerless.”
