It all begins when Kyle starts noticing strange inconsistencies in Sienna’s story. Her alibis don’t line up, her explanations for her sudden

wealth sound rehearsed, and her connection to Noah Newman raises too many questions. Ever since she entered Kyle’s life under

mysterious circumstances, fans have suspected Sienna was hiding something — and now, those suspicions are confirmed.

 

 

In this week’s explosive Y&R episode, Kyle takes matters into his own hands. Determined to protect his family and the Abbott legacy, he quietly begins investigating Sienna’s past. With the help of Jack Abbott’s trusted contacts and Phyllis’s tech-savvy instincts, Kyle uncovers a trail of deceit and manipulation that leads straight back to Sienna.

The turning point comes when Kyle discovers a set of bank transfers linked to an offshore account — all under Sienna’s name, but funded by a familiar source connected to Newman Enterprises.

“You’ve been lying from the start, Sienna,” Kyle says in a tense confrontation. “And now, I can prove it.”

The Moment of Truth: Sienna’s Breakdown

 

 

Cornered and unable to escape, Sienna initially tries to deny everything. She accuses Kyle of paranoia and insists he’s been misled by others — particularly Audra, who has her own history of manipulation.

But when Kyle produces the final piece of evidence — a recording of Sienna meeting secretly with a Newman insider — the façade crumbles.

In a gripping, emotionally charged scene, Sienna breaks down and confesses the entire truth.

“I didn’t mean for it to go this far,” she sobs. “I was desperate… they promised me it would only be temporary.”

Her shocking confession reveals that she was recruited as a spy inside Jabot, tasked with gathering information on Abbott operations and sabotaging Kyle’s efforts to expand the company’s digital division. The orders came from someone high up — and fans are already speculating that Victor Newman may have had a hand in orchestrating the scheme.

Kyle’s Fury Erupts

The moment Sienna admits the truth, Kyle’s world collapses. He’s been betrayed before — by love, by business partners, even by family — but this hits differently. He trusted Sienna, even defended her when everyone else doubted her.

“You played me,” Kyle says coldly. “You used me to destroy everything I’ve worked for. And for what? Money?”

The heartbreak on Kyle’s face says it all. His emotions shift rapidly from anger to disbelief, then to deep sadness as he realizes how easily he was manipulated.

Sienna tries to explain that she never intended to hurt him, that she fell in love for real somewhere along the way. But it’s too late. The damage is done, and Kyle can’t bring himself to forgive her — not this time.

The Fallout in Genoa City

Word of Sienna’s betrayal spreads quickly, sending shockwaves through the Abbott and Newman families alike. Jack is furious that his son was targeted, while Diane fears this could reopen old wounds between the two powerful clans.

Meanwhile, Phyllis wastes no time digging deeper into the mystery, suspecting that Sienna might not have acted alone. Her instincts tell her that this scheme is just one piece of a much larger corporate war brewing beneath the surface of Genoa City.

Audra, on the other hand, seems almost pleased by the chaos — though no one can quite tell whether she’s involved or just enjoying the spectacle.

Fans online have gone wild with theories: could this betrayal tie into Victor Newman’s ongoing feud with the Abbotts? Or is there another puppet master pulling Sienna’s strings — perhaps even Tucker McCall, looking to stir up trouble for Jabot?

A Devastated Kyle Faces a Choice

After the dust settles, Kyle finds himself alone at Society, replaying the confrontation in his mind. He’s hurt, humiliated, and furious — but also haunted by Sienna’s words. Despite everything, part of him wonders whether her feelings were ever real.

Jack urges his son to stay strong and focus on protecting the Abbott name, while Diane tries to comfort him as a mother. But Kyle’s heart remains conflicted. Should he press charges and expose Sienna publicly — or walk away and try to rebuild his life quietly?
