Trivia: This series was originally announced as "Agatha: House of Harkness" in 2021. The subtitle was then changed to "Coven of Chaos" in July 2022, before being changed again to "Darkhold Diaries" in September 2023. It was then officially confirmed to be titled "Agatha All Along" in May 2024. The previous titles were all probably announced as jokes to lead up to the actual title, given that "Agatha All Along" was the name of the song used to reveal Agatha being the main antagonist of WandaVision.
Trivia: SPOILER: This series marks the MCU debut of the personification of Death, as played by Aubrey Plaza. In the comics, Death has unreciprocated romantic feelings from Thanos, and she was the impetus for him acquiring the Infinity Stones and using them to wipe out half of all life in existence.
Trivia: Watch the fake opening for "Agnes of Westwood"; at three points (just after Agnes O'Connor's name disappears, as soon as Herb Feltman's name appears, and when Mrs. Hart's name is on screen), there are very quick cuts to seemingly dead women. And indeed dead they are; they are witches Agatha will kill (or rather, has killed) in the very last episode (from the first and the second encounter in the Witches' Road montage).
