A major casting shake-up is sending shockwaves through the world of daytime television, and longtime fans of Days of Our Lives are already buzzing with theories.

According to insiders close to production, actress Sofia Mattsson—best known for her powerful run on General Hospital—has officially joined the cast of the iconic NBC drama.

Even more intriguing, whispers from the set suggest she could be stepping into one of Salem’s most emotionally charged roles: Abigail DiMera.

The news has ignited intense speculation across the soap community. If the rumors are true, Mattsson’s arrival could mark the return of one of the show’s most beloved—and tragically lost—characters.

A Daytime Star Crosses Over

For years, Sofia Mattsson captivated audiences as Sasha Gilmore on General Hospital, a character who endured heartbreaking struggles, complicated romances, and devastating personal losses. Through it all, Mattsson brought a unique blend of vulnerability and fierce determination that made Sasha one of Port Charles’ most compelling figures.

Her ability to portray layered emotional journeys earned her a loyal fan following. Whether Sasha was confronting family secrets or fighting to rebuild her life after tragedy, Mattsson consistently delivered performances that resonated deeply with viewers.

Now, the actress is reportedly bringing that same dramatic intensity to Salem.

Sources indicate Mattsson has already begun filming scenes, though her first appearance on-screen is expected sometime in early 2027. The delayed debut is typical for the show’s production schedule, but that hasn’t stopped speculation from exploding online.

The biggest question on everyone’s mind: who exactly will she play?

Could Abigail DiMera Be Returning?

Among longtime fans, one theory has quickly gained momentum—the possibility that Mattsson will take over the role of Abigail DiMera.

If true, the development would represent one of the most dramatic character returns in recent Days of Our Lives history.

Abigail, the beloved wife of Chad DiMera and daughter of Salem favorites Jennifer Horton and Jack Deveraux, was once at the center of one of the show’s most cherished love stories. Her relationship with Chad evolved from complicated beginnings into a passionate marriage that captured viewers’ hearts.

Together they built a family and faced countless trials—from kidnappings and rivalries to corporate battles within the powerful DiMera dynasty.

But their love story took a devastating turn when Abigail was killed in a storyline that shocked viewers and left a permanent scar on Salem.

At least, that’s what fans were told.

The Mystery of Abigail’s Death

Almost immediately after Abigail’s supposed death, viewers began noticing strange inconsistencies surrounding the storyline. For one thing, the circumstances of her demise felt suspiciously murky—something longtime soap watchers know is rarely accidental.

Then came the unsettling detail that truly fueled speculation: Abigail’s body mysteriously disappeared from the morgue.

In Salem, disappearing bodies have historically been a sign of only one thing—an eventual resurrection.

The town’s history is filled with miraculous returns from the dead, especially among members of the powerful DiMera family. After all, their infamous patriarch Stefano DiMera practically made cheating death a family tradition.

For fans, the missing body felt less like a plot hole and more like an intentional setup.

If Abigail wasn’t truly dead, where had she been all this time?

Chad’s Life Without Abigail

Since losing his wife, Chad has struggled to rebuild his life. The once-confident businessman has often appeared emotionally adrift, focusing on raising their children while trying—and frequently failing—to move forward.

Even when he attempts to embrace new relationships or opportunities, the memory of Abigail continues to loom over him.

Her absence has shaped many of his choices, leaving viewers with the lingering sense that his story remains incomplete.

If Abigail were to return now, the emotional consequences would be enormous.

Chad would be forced to confront years of grief, anger, and unanswered questions. Their children would suddenly find themselves reunited with a mother they barely remember.

And the entire DiMera family could be thrown into chaos.

EJ DiMera’s Dangerous Power Play

Timing may be everything when it comes to Abigail’s potential return.

Salem is currently in the midst of another ruthless power struggle within the DiMera empire, led by the cunning and unpredictable EJ DiMera.

EJ has been maneuvering aggressively to consolidate his power, targeting allies and enemies alike with strategic precision. His schemes often involve psychological warfare just as much as corporate manipulation.

For a mastermind like EJ, the sudden reappearance of Abigail would be the ultimate chess move.

Such a revelation could destabilize Chad emotionally while giving EJ leverage over multiple members of the DiMera family. The shockwaves would ripple through Salem, reigniting old rivalries and sparking new alliances.

And if Abigail had been hidden away for years, the question of who orchestrated her disappearance would become the biggest mystery in town.

Sofia Mattsson’s Potential Impact

If Mattsson is indeed taking over the role, she could bring a compelling new dimension to Abigail.

The character has always been portrayed as resilient, compassionate, and fiercely loyal to those she loves. But years spent missing—possibly in captivity or hiding—could dramatically reshape who Abigail has become.

Mattsson has already proven her ability to portray emotionally complex women navigating trauma and survival. Her version of Abigail might carry deeper scars and a darker edge than audiences remember.

Perhaps she returns suffering from memory loss, unsure of who she can trust.

Perhaps she has spent years gathering evidence against the people responsible for her disappearance.

Or perhaps she has her own secret agenda that could change everything.

Whatever direction the story takes, Mattsson’s acting range suggests she could deliver a powerful reinvention of the character.

The Ripple Effects Across Salem

Abigail’s return wouldn’t only affect Chad.

Her parents, Jack and Jennifer, would be forced to confront the shocking truth that the daughter they mourned might still be alive. Their reunion alone would promise some of the most emotional scenes the show has delivered in years.

The Horton and DiMera families—longtime rivals with intertwined histories—could once again find themselves pulled into another explosive conflict.

And Salem’s delicate balance of power might never be the same.

A Classic Soap Opera Comeback?

Of course, nothing has been officially confirmed about Mattsson’s role. Producers remain tight-lipped, and daytime television is famous for misdirection.

She could be playing an entirely new character—a mysterious newcomer with ties to Salem’s past or a rival determined to disrupt the DiMera dynasty.

Still, many fans believe the clues are too strong to ignore.

The unresolved mystery surrounding Abigail’s death, the missing body, the current DiMera power struggle, and Mattsson’s arrival all seem to align perfectly for a dramatic resurrection storyline.

And if soap history has taught viewers anything, it’s that no one in Salem stays gone forever.

For now, fans will have to wait until 2027 to learn the truth. But one thing is certain: the mere possibility of Abigail’s return has already reignited excitement across the Days of Our Lives fandom.

Because in Salem, secrets always surface eventually—and when they do, they have a way of changing everything.
