Jan's Bassoon Cleaner
In Season 1, when the trio first snoops through Tim Kono’s apartment, they find a box of his intimate items. Among them is an odd-looking tool they dismiss as a quirky toy. Only later is it identified as a bassoon cleaner. This is a huge clue pointing
directly to Charles’s new girlfriend, Jan, the resident bassoonist. On first viewing, it’s an easily missed detail among many red herrings. On rewatch, knowing Jan is the killer, this item is a glaring piece of evidence hiding in plain sight, implicating her from the very beginning.
Tim Kono's Trash Bag
When the trio first encounters Tim Kono on the elevator moments before his death, he's holding a trash bag. This seems unremarkable, until a podcast fan points out that Tim lived on the ninth floor but got on the elevator at the sixth. Why would he be taking out someone else's trash from a different floor? The finale reveals he was leaving Jan's apartment on the sixth floor after she poisoned him. The trash bag was hers. On a rewatch, this small, seemingly mundane action becomes a critical piece of the timeline, confirming his secret relationship with his killer.
Mabel's Knitting Needle Dream
In the very first episode, while introducing herself, Mabel mentions a recurring dream where she stabs an intruder with her knitting needle. At the time, it just seems like a quirky, dark character detail. But it’s brilliant foreshadowing for two key events. First, it hints at her defensive capabilities, which we see later in the season. More importantly, it directly sets up the Season 2 mystery, where she is discovered kneeling over Bunny’s body, who has been fatally stabbed with—you guessed it—a knitting needle.
Bunny's Last Words
Bunny Folger's final, cryptic words to Mabel were “14, Savage.” For most of Season 2, the trio and the audience are stumped. They chase theories related to the 14th floor or Charles-Haden Savage. However, on rewatch, the answer is tied to a seemingly unrelated scene. The killer, Poppy White, orders a specific sandwich—number 14 on the menu—at the local diner. Bunny wasn't saying “Savage,” but “sandwich.” This misheard clue, which feels like a dead end for so long, becomes the key that unlocks the entire case once you know where to look.
Poppy Sitting Under Her Own Missing Poster
Poppy White, Cinda Canning’s ambitious assistant, reveals late in Season 2 that she is actually Becky Butler, the subject of Cinda's hit podcast All Is Not OK in Oklahoma. While this feels like a sudden twist, the show visually hinted at it earlier. In one episode, there's a scene where Poppy is sitting directly underneath a “Where Is Becky Butler?” promotional poster. The first time you see it, your focus is on the dialogue. The second time, it’s an incredibly cheeky visual gag from the creators, telling us the answer was right there all along.
The Sneeze in the Secret Passageway
While hiding in the Arconia's secret passageways, Charles’s quasi-daughter Lucy hears someone enter and then sneeze. This becomes a key piece of testimony, but the identity of the sneezer remains a mystery. The clue pays off when Poppy’s allergy to birds is revealed. Bunny owned a parrot, Mrs. Gambolini. On rewatch, the moment Lucy hears that sneeze, it's no longer just a random event but a direct link to Poppy, who was in the passageways on the night of Bunny's murder.
The Mother-Son Producer Duo's Kiss
In Season 3, the relationship between producers Donna and Cliff DeMeo is presented as uncomfortably close, often sealed with a kiss on the lips. This recurring, slightly jarring interaction is more than just a character quirk. It establishes the intense, ride-or-die bond between them. This dynamic becomes central to the motive, with Donna poisoning Ben Glenroy to protect her son's producing debut from a bad review, and Cliff later pushing Ben to his death to protect his mother. The kiss is a visual motif for their toxic codependency.
Donna's Lipstick on Cliff's Handkerchief
The key piece of evidence found on Ben Glenroy's body is a handkerchief with lipstick on it. Donna eventually confesses to poisoning Ben, and the lipstick seems to confirm her guilt. But Mabel realizes something is off. She recalls seeing Donna blot her lipstick on Cliff's handkerchief before tucking it into his pocket as a good luck charm. This means while the lipstick was Donna's, the handkerchief belonged to Cliff. On a rewatch, this seemingly minor pre-show ritual becomes the detail that unravels the whole case, proving Cliff was the one present at the final, fatal confrontation.
