Time-Locked Cursive-Reading Ability is one of the comic stories of the unofficial Charlie's Head Is In The Hatbox ‘verse, created by Rain N. Thirteen. It features Rain's World's Rain and Diego Santiago and also mentions its Hatbox Ghost (Charlie Hatfield).
Having received Charlie Hatfield's letter, the siblings Rain and Diego bicker about who'll get to read it first. When Rain gets the upper hand, it turns out that the letter is, in any event, written in such cursive handwriting as to be nearly illegible — at least in Rain's current state of sleep-deprivation.
- This story follows through on Charlie Hatfield's resolution in Hatbox Diary… Diaries??? Anyways… (2020) to contact some expert on “multiverse stuff” to resolve the “problem” (the expert here turning out to be Rain).
- Rain's Journal (Entry 403) (2021), released the same day as this comic, is a direct sequel to it, presenting Rain's thoughts after they have read Charlie's letter.
