Summer Bay is heading straight into emotional chaos this Thursday, with Episodes 8645–8647 delivering a triple punch of relationship fractures, buried trauma,

and desperate attempts to hold love together. What begins as simmering tension quickly erupts into confrontations that could permanently change the futures of several fan-favorite couples.

At the center of the storm are Justin and Leah, who find themselves at a devastating impasse. After months of unresolved issues, miscommunication, and emotional exhaustion,

the cracks in their marriage are no longer something they can paper over. Sources close to the storyline reveal that neither Justin nor Leah is willing to back down this time — and that’s what makes the situation so dangerous.

Justin is consumed by frustration, convinced he’s been carrying the emotional load alone, while Leah feels unseen and unsupported when she needs him most. Their conversations spiral into accusations rather than understanding, leaving both questioning whether love is enough to bridge the growing distance. With neither prepared to compromise, viewers are left wondering if this stalemate marks the beginning of the end for one of Summer Bay’s most resilient couples.

Meanwhile, Lacey is blindsided by a powerful emotional trigger that sends her spiraling. What initially appears to be a minor moment quickly unlocks deeply buried memories, forcing her to confront trauma she’s been desperately trying to outrun. Those closest to her are alarmed by how fast her emotional state deteriorates — and by how determined she is to shut everyone out.

As Lacey struggles to keep herself together, her reactions become increasingly volatile, raising fears that she could make a decision she can’t undo. The episode hints that her past is far darker than many realized, and the fallout from this trigger may ripple far beyond her own storyline, dragging others into a crisis they never saw coming.

Elsewhere, Abigail takes a completely different approach to emotional damage control — but her plan may be just as risky. Desperate to reclaim the spark she feels slipping through her fingers, Abigail sets her sights on an ambitious anniversary re-do, convinced that recreating happier memories will fix what’s broken. But as Home and Away fans know all too well, grand gestures rarely go to plan in Summer Bay.

What Abigail doesn’t account for is how fragile the relationship truly is. Instead of healing old wounds, the anniversary re-do threatens to expose unresolved resentments and unspoken doubts. As tensions simmer beneath forced smiles and staged romance, the question becomes painfully clear: is Abigail fighting for love — or fighting against the truth?

By the end of Thursday’s episodes, nothing feels stable. Justin and Leah are standing on opposite sides of an emotional battlefield, Lacey’s inner turmoil is dangerously close to boiling over, and Abigail’s well-intentioned gamble risks accelerating the very breakup she’s trying to prevent.

With emotions raw and consequences looming, Episodes 8645–8647 promise a gripping run that reminds viewers why Home and Away remains unafraid to explore the messy, heartbreaking reality of love, loss, and survival. One thing is certain: by the time the credits roll, Summer Bay will not be the same — and neither will the people who call it home.
