Summer Bay is about to be rocked by a revelation that will redefine family lines and reopen old wounds, as Home and Away tees up one of its most shocking twists in years. In upcoming episodes, Dana Matheson stumbles upon a secret that changes everything she thought she knew about Sonny Baldwin—he is the long-lost son of Summer Bay icon Alf Stewart.

The discovery comes not through a dramatic confession, but via a quiet trail of clues that Dana can’t ignore. What starts as a minor inconsistency—a name on an old document, a date that doesn’t quite add up—spirals into a truth with the power to fracture friendships and rewrite the town’s history.

A puzzle Dana can’t unsee

Dana’s curiosity is piqued when she notices Sonny’s reaction to a seemingly harmless comment about Alf’s past. It’s fleeting, but loaded. From there, she uncovers a paper trail pointing to a brief relationship Alf had decades ago—one that ended abruptly, without explanation. The timelines match. The details align. And the realisation lands with a sickening thud.

When Dana confronts Sonny privately, the tension is electric. He doesn’t deny it. Instead, he admits he’s known the truth for years—and that he came to Summer Bay torn between wanting answers and fearing the fallout.

Sonny’s secret life

According to Sonny, his mother raised him away from the bay, determined to protect him from a life overshadowed by a powerful name. Alf, he says, was never told. Or if he was, the message never reached him. Sonny insists he never planned to reveal the truth—especially not now, when Alf is a pillar of the community and the emotional centre of so many lives.

“I didn’t come here to blow things up,” Sonny confides. “But once you’re here… the past has a way of finding you.”

The weight of telling Alf

Dana is left carrying an impossible burden. Alf Stewart isn’t just a local legend—he’s family to half the town. The idea that he might have a son he never knew about feels both miraculous and cruel. Dana wrestles with whether the truth will heal old scars or create new ones that never fade.

As the secret inches closer to exposure, viewers will watch Dana unravel under the pressure. Her loyalty to Sonny clashes with her respect for Alf, and the longer she waits, the heavier the truth becomes.

Fallout that will change Summer Bay

Producers tease that the reveal—when it comes—will be quiet, devastating, and unforgettable. There are no shouting matches, no theatrics. Just two men facing the years they lost, and a town forced to reckon with a rewritten legacy.

The ripple effects are enormous. Relationships shift. Trust is tested. And Sonny must decide whether he wants a place in Alf’s life—or whether some truths arrive too late to fix what they break.

One thing is certain: Summer Bay will never look the same. With Dana holding the match and Sonny standing in the blast radius, Home and Away is setting the stage for a reckoning that proves once again—no secret stays buried forever.
