When The Bold and the Beautiful introduced Lisa Yamada as Luna Nozawa in the fall of 2023, Forrester Creations’ new intern seemed too good to be true. Spoiler alert: The secretly shady lady was too good to be true.

Luna’s mother Poppy warned her to steer clear of the Forresters. But… um… why, exactly? We would soon discover that the affluent Angelenos were in danger from Luna, not a danger to her!

Poppy’s sister Li read Luna the riot act for taking a job at Forrester Creations. The doctor’s reason for doing so? Who knows? It did not appear that Li was even remotely aware that Luna had a dark side.

Immediately, virginal Luna fell into a serious romance with Forrester golden boy R.J. And thus, her reign of terror really began. She was so sickly sweet with him that she threatened to give everyone in their vicinity diabetes.

Luna was completely and totally devoted to R.J. — to the point that she rebuffed his handsome cousin Zende’s every attempt to seduce her. A confounding move, considering the next step in what we would be told had been her master plan all along.

After mixing bubbly and a few of Mom’s “special mints,” a loopy Luna slept with Zende. She’d later reflect on the tryst as the best sex of her life, but that was just a bonus. Her real goal, she’d explain, was “exposing” Poppy’s drug use. Why? Just wait.

Luna actually only fake-cried over her one-nighter with Zende for a few weeks. But it wasn’t just an excuse to lounge around in fuzzy slippers and eat chocolate. Somehow, the show insisted, this was part of a scheme that would result in her getting super-rich Bill Spencer named her biodad.

For “reasons,” Poppy began hinting that yes, Bill might be Luna’s father. So why had Poppy initially denied the possibility? And how come Luna waited until the long-ago lovers had reconnected to target his deep pockets? Beats the hell out of us.

After Li’s DNA test proved that Luna was a Spencer, Bill fell right into her trap and had new family portraits taken. “No, Liam and Wyatt and Will, your presence is not required. I am all about my daughter now!”

We still had no idea just how diabolical Luna was — or that she was diabolical at all — when Bill offered to adopt her. Which seemed unnecessary since he was supposedly her father, but whatever. She quickly grew accustomed to the VIP treatment at Il Giardino.

So far as we saw, Luna never met Tom Starr, the down-on-his-luck former rocker who insisted to Poppy that he was the young woman’s pop. But thanks to the letters he’d written Poppy over the years, Luna knew he was a threat to her plan and — gulp — eliminated him.

Not really. But Luna apparently drugged herself and slept with Zende just as preparation to frame her own mother for Tom’s murder. Mind you, he hadn’t even arrived on the scene yet when Luna “accidentally” shagged Zende. So… um… huh?

When Hollis the Waiter happened upon Tom’s revealing love letters to Poppy, Luna ensured that he had served his last breadstick and let Mom get arrested for the crimes. But by then, Luna had an even bigger problem.

Bill’s busybody ex Katie Logan had been instrumental in getting Poppy out of the picture. But Luna wasn’t able to alter the results of the second DNA test on which Katie insisted. No matter. Luna still made Bill the answer to the question of…

If Luna wasn’t going to get a fat allowance from Bill, she figured that she could cash in another way — by enticing her father figure to tell her an especially scandalous bedtime story. Even the Stallion was like, “Whoa, Nellie!”

After Steffy Forrester got an eyeful of Luna paying lip service to Bill, she confronted her half brother’s girlfriend. Whereas everyone else who crossed Luna wound up dead, Steffy got lucky: She was only locked up.

Thanks to the keen intuition of Luna’s incredibly smart cousin Dr. Finn Finnegan, Steffy was found and her captor, busted. But surely Luna would have another trick up her sleeve, right? Why else wear sleeves? In L.A.? Come on!

Over and over, Luna wrote to Bill and insisted that she didn’t know what had come over her. She wasn’t the kind of person who’d commit a double murder. Maybe a single, but… Anyway, once Bill saw how she was being treated in prison, he worked his magic and got her released into his custody. Because that’s totally a thing that can happen.

No sooner had Luna and Bill established that they’d never really been hot for one another than his secret houseguest became infatuated with his son, Will. And just after his girlfriend Electra Forrester had escaped from the clutches of another psycho! What are the odds?

The longer Luna stayed at Bill’s, the more she and her savior bonded over their horrible upbringings — yes, even though she’d always said that she and her mom had had an unconventional but fun life. Now and then, Luna also dissed Tom as a “one-hit wonder.” Mm-hmm. ’Cause nothing says “I’m truly remorseful” like insulting your murder victim posthumously.

Meanwhile, Li got it in her head that ex-husband Jack had knocked up Poppy way back when. But a paternity test proved that Luna didn’t owe him any Father’s Day cards. So, once and for all, who the hell was her dad? Li probably wasn’t going to like the answer at which we arrived.

No sooner had Remy Pryce, aka Will Spencer’s new girlfriend Electra Forrester’s stalker, started doing odd jobs around Bill’s estate than he and Luna became fast friends. You know the one thing that was missing from that particular recipe for disaster? This psycho waitress.

Years after the fact, Luna’s cousin Finn Finnegan got it in his head that “Hey, ya know what? Maybe the fact that I had sex with Aunt Poppy means that her daughter is also… oh my God, my daughter!” He was right, too!

After getting a mysterious text, Finn showed up at Bill’s and eventually — OMG, he hemmed and hawed for a whole episode — got around to telling Luna that he is the dad that she should have had all along. Read her portrayer’s take on Luna’s reaction here.

Even before learning that her cousin is her father, Luna had begun talking like she was preparing to mount a dissociative-identity disorder defense in order to get a retrial for Tom and Hollis’ murders. With Finn’s support and Bill’s money, would she soon be a free woman?
