- “My diary? You read my diary? That is not okay! A diary is like a person's most private place!”
- ―Buffy Summers[src]
Buffy Summers kept a personal diary in which she wrote about her experiences, thoughts, and feelings. She was specially protective of others taking it or reading her secrets.
In 1997, after Angel had spent the day in her room, Buffy found her diary misplaced and though he had read it. In attempt to cover the attraction for him she had described in the diary, she ended up mentioning that she had written he was “hunk” and his eyes “penetrating". He was identified in her entries with the initial “A”, which Buffy tried to argue it actually referred to “Achmed, a charming foreign exchange student,” lying that he was the actual object in the description of a certain fantasy.
In the same year, the robot Ted Buchanan went through Buffy's personal items in her absence, and found out she was a Slayer after reading her diary. With this, Ted told her the supernatural events she described were evidences that she was delusional, and he threatened to obey him for then on, or he'd show the diary to her mother so Buffy would be taken away to a mental institution. As she attempted to take her diary back from him, Ted attacked her, and the two fought until he fell down the stairs in apparent death.
In 1999, Sunday's gang robbed Buffy's belongings from her dorm at University of California, Sunnydale. In their nest, Buffy discovered this included her diary, and was able to intervene as soon as Rookie started reading it. Buffy retrieved the diary and all her things after she defeated the vampire gang.
Behind the scenes
- In the non-canon story Slayer, Interrupted, Part One, a ten years old Dawn finds Buffy's diary and shows to her parents the writing about her being the Slayer. This is developed as the cause for them to take Buffy to a mental institution, as Ted would threaten her ten years later.
