In Eric's office, Ridge and Brooke kissed. Brooke proposed that they work out in the company gym. Ridge thought she was talking about his pudge, but she clarified that she needed to get in shape and look good for the Bedroom line.
R.J. arrived with Ridge's pizza, and his parents noticed something was wrong with him. He said it was about Luna's mother, Poppy. R.J. wasn't sure if he should talk about it with them. Brooke asked what it was, and R.J. revealed that Luna had found Tom Starr's backpack. It had just shown up at Luna and Poppy's apartment, full of letters claiming that he was Luna's biological father.
Later, R.J. shared Katie's theory, and Ridge sighed heavily at the notion that Poppy was responsible for two deaths. R.J. wondered how Hollis had gotten dragged into it. Brooke replied that they didn't know what "this" was. Claiming not to want to spread information, R.J. said the letters were proof that Tom had been pressuring Poppy, and it wasn't a stretch to think Poppy might do something to stop him.
Brooke reasoned that Poppy had gotten a DNA test to prove Bill wasn't the father, but it had turned out that he was. Ridge murmured that tests weren't foolproof. Brooke wondered if Poppy had felt cornered by Tom, causing her to do the unthinkable. R.J. didn't agree with Katie but couldn't dismiss her ideas, either. R.J. and Ridge agreed that murder for the proposed motive was a bit extreme. R.J. said it would devastate Luna if it were true.
Ridge continued to point the finger at Sheila. Brooke agreed but could understand her sister's opinion. Ridge asked what Katie intended to do with the information. R.J. worried about Luna if the police questioned Poppy.
At Il Giardino, Liam and Will met for lunch. Liam joked that Will had forgotten he had an older brother. Liam was glad not to be on video chat and joked that they made Will look fat. Liam brought up Will's awkward return home and figured Poppy had been mortified, too. Will said Poppy wasn't what he had thought she'd be, and he had his doubts about Poppy and Luna.
Liam asked how Will felt about Luna. For Will, it was too soon to really know, but he thought it was really strange that the woman had suddenly decided to do a paternity test and had hit paydirt overnight. Will noted that Poppy and Luna were living large in what had once been Will's home. Liam replied that it was still Will's home. Will knew it but said Bill was very different due to the Nozawa women. Liam wasn't ready to form an opinion because he hadn't spent a lot of time with them, but it was apparent to him that Will thought Luna and Poppy were questionable.
Will wondered if Bill was in love with Poppy and had gotten over Katie. Liam declared that Bill would never get over Katie, and he had a son with her. Will replied that Bill had a daughter with Poppy. Liam acknowledged it but said Bill hadn't gotten where he was without reading people exceptionally well. Will agreed but remained leery of Poppy.
At Bill's house, Luna entered behind her mother as Katie announced that she was there to warn Bill about Poppy. Poppy called Katie a jealous ex-wife who was constantly invading their lives and causing trouble. Poppy asked Katie to leave. "Are you ordering me out of Bill's house?" Katie asked. Poppy said she was being as polite as she could be, but Katie refused to go.
Katie asserted that Poppy had motive to kill. Poppy asked how many times she had to say she'd had nothing to do with the deaths, but Katie claimed that the facts spoke for themselves. Two men had overdosed on the same drug. Poppy deemed it a coincidence, but Katie asked if the backpack full of letters from Tom, claiming to be Luna's father, was a coincidence, too.
Poppy gazed at Luna, who looked away. Katie continued, saying she'd talked to Sheila, who had spoken to Hollis about the backpack the day he'd died. Katie claimed that two people who'd known about the letters that could upend Poppy's life with Bill had mysteriously died of the same drug. Luna interjected that the deaths were senseless accidents.
Poppy asked how Katie had known about the letters, and Katie readily revealed that it had been R.J. "Did you...?" Poppy said to Luna. Luna began stammering that she'd been upset. Poppy guessed R.J. had run straight to his aunt. Katie said he hadn't really wanted to tell Katie about Poppy's secret meeting with Tom before his death or that Poppy had told Luna not to worry because Poppy had taken matters into her own hands.
Katie claimed it didn't take a genius to see that Poppy had killed because Hollis and Tom had been in the way of Poppy's life with Bill. Bill asked why Poppy had gone to see Tom. Poppy informed him that she'd told Tom to stop harassing them because she had a paternity test that proved Bill was Luna's father. Bill claimed he had people who could have handled it, and he asked why she'd gone alone in secret.
Poppy admitted that, in hindsight, she should have gone to him first, but Katie said Poppy hadn't known if Bill would send her packing for keeping the truth from him. Poppy asked Bill not to listen to Katie, who didn't know what she was talking about. Katie insisted that she did. She told Bill to get another test to ensure Luna was his daughter.
There was a knock at the door. "I'll get that," Katie said, taking it upon herself to answer the door. Chief Baker entered, and Katie announced that she'd called him and told him what she'd learned about Poppy. There to follow up, Baker said they'd gotten a search warrant for Poppy's apartment, and that had been where they'd found "this." He pointed to Tom's backpack.
Poppy asserted that she hadn't done anything wrong. Chief Baker said he was there with evidence. Bill replied that he knew all about the backpack and letters. Baker asked if they'd talked about what else had been in the backpack, and he pulled out a baggie containing a pill case that looked like Poppy's mints case. "Drugs," Baker stated.
Baker guessed Bill recognized the case. Poppy said it was insane. She didn't know how the backpack had gotten into her apartment or about the tin or drugs. Katie asserted that it was the same drug Poppy took, but Baker added that it was laced. Poppy denied it, asking Bill to believe her. Baker said she'd been with Tom before he'd died, the drugs connected her to both crimes, and they had motive and evidence. Baker announced that they were taking her in.
Luna asked if Poppy had really done it. Poppy denied it. Luna asked if Bill was really her father. Poppy affirmed it, saying Li had done the test. Poppy swore she was innocent, and the police and Katie were wrong. Bill told Baker to do what he had to do, but Bill hoped none of it was true. The police handcuffed Poppy, and Baker read Poppy her Miranda rights and took her away.
