Before the Series
When Kit was four years old, the same age as the Denouement Triplets, the schism began in V.F.D. As she grew up, she played a major role in the Volunteer side of the schism. It is implied that she once was in a relationship with Count Olaf, but was also the object of Dewey Denouement's affections.
In The Grim Grotto, it is revealed that Kit assisted Captain Widdershins in the construction of the Queequeg. She and her brothers fought against Cafe Salmonella after the restaurant wiped out the fleet of V.F.D. salmon. Kit also wrote a letter to her friend Gregor Anwhistle, warning him about the danger of the Volatile Fungus Deportation program.
According to Lemony Snicket's autobiography, she went to Prufrock Preparatory School disguised as a teacher (Ms. K), replacing Mr. Remora after he choked on a banana and retired. She had her students read books relating to V.F.D. Nero fired her when he read an article in The Daily Punctilio supposedly given to him by Mr. and Mrs. Spats, that forbade that particular list of books. When Nero informed her of his decision, Kit grabbed two orphaned students by the ankles and ran off, recruiting them into V.F.D. It is unknown who the students were or if they featured in the books at any point.
A Series of Unfortunate Events
The Slippery Slope
Though her name is not mentioned, Kit Snicket must be the addressee of Lemony Snicket's letter hidden in Chapter 5 of The Slippery Slope, as it is addressed to 'My dear sister'.
The Grim Grotto
At the climax of The Grim Grotto, Kit meets the Baudelaire orphans on the Briny Beach, tells them her name and takes them away in a taxi.
The Penultimate Peril
In The Penultimate Peril, it is revealed that she was taking them to a meeting at Hotel Denouement where she would give them their mission. By this time she was pregnant, and it is implied in the narration of chapter 9 she was the love interest and possibly even the wife of Dewey Denouement.
Kit washes onto the coastal shelf near the island aboard a raft of books with both legs injured and informs the Baudelaires of the fates of the Quagmires, Fiona, Fernando, Captain Widdershins and Hector.
In chapter 13 it's revealed she and Count Olaf had a previous romantic relationship. She dies after being poisoned by the Medusoid Mycelium just before giving birth to her daughter, who is named after the Baudelaires' mother, Beatrice. Her grave is on the island where Ishmael facilitated. When visiting her grave, the Baudelaires often left flowers in her memory.
Her final lines in the series quote an excerpt of a poem written by Francis William Bourdillon: "The night has a thousand eyes, and the day but one; yet the light of the bright world dies with the dying sun. The mind has a thousand eyes, and the heart but one: yet the light of a whole life dies when love is done."
