During one of her charity streams, Dana Terrace released the audio for a supposedly cut episode featuring three characters (Hunter, Luz and Lilith) writing their experiences.

Hunter's palisman observations

Lilith's letter

Luz's diary entry

Supposedly, it was cut as it was mostly a "filler" episode, but it does unveil some new information about the characters. In particular:

• Lilith's letter contains a mention of her being Aro/Ace, which is never mentioned in the show!
• Meanwhile, Hunter spends some time with Flapjack, and his observations contain a foreshadowing of Belos belonging to the human world, as he's the only one who knows what a flapjack is ("Damn you, pancakes!" may be the funniest line in the entire series - I'm sad it was cut!).
• Luz's diary contains the least amount of notable information: the only new piece of info is her mom being lactose intolerant, and a foreshadowing of Amity and Willow "working out some things", which eventually happened off-screen in an unfortunately cut scene in S02 EP18 "Labirinth Runners" (I'll talk about more dropped/cut plot points in another post).

Luz's diary also contains enough evidence to put these entries in a narrow time frame: she mentions "seeing my mom in the rain", but also that "Philip" is a smart dude, indicating that she hasn't uncovered his identity yet. This means that these entries are being written between S02 EP10 "Yesterday's Lie" (the episode where Luz talks to her mom) and S02 EP16 "Hollow Mind" (where Luz discovers Philip's identity). Depending on how much you want to read into Luz calling Philip "smart", the time frame may be shortened to S02 EP12 "Elsewhere and Elsewhen", where Luz meets a very unpleasant Philip.
