If the Season 13 WebD Exclusive is indeed the flash-forward finale, it offers a devastating conclusion: Charles dies of natural causes mid-episode. Oliver loses his hearing. Mabel moves to Prague.
But because it is a WebD Exclusive, the episode ends with a title card: "To solve the final mystery, delete this file and re-download it in 2027."

Season 13 opens with Charles, Oliver, and Mabel launching their most ambitious project: a live interactive podcast from the Arconia’s newly restored theater. But during the first episode, a body is discovered in the soundproof booth—wearing Oliver’s signature scarf. The victim? The host of a rival true-crime podcast called “WebD Witness.” The twist: the murder was livestreamed, but the only person who didn’t see it was the trio, because they were on a bathroom break.
Before we dive into the mystery of Season 13, we need to decode the "WebD" part of the keyword.

Here is the synopsis (translated from the leaked metadata source code):
"Charles, Oliver, and Mabel, now in their twilight years, reunite for one final episode of their podcast. The Arconia has been converted into a luxury time-share. A new victim has been found in the boiler room—but the body has been there since 2024. Using advanced DNA tech and senile recollection, the trio realizes the murderer of Sazz was never caught. The 'WebD Exclusive' refers to a fully interactive digital evidence board that viewers can control."
If true, this means the "Exclusive" aspect is technological. Viewers watching this specific WebD release would be able to click on evidence tags, listen to alternate audio confessions, and choose which suspect to interrogate—turning the episode into a playable visual novel.
