Mallory and Jessi joined the club at the same time, in Hello, Mallory. At this time, the club was looking for a new member because Stacey McGill had just moved back to New York City. The girls of the club were wary of Mallory, and gave her a bunch of tests. Mallory then created a new club Kids Incorporated, with Jessi Ramsey who was new to town at the time. When that failed, the BSC allowed both girls to join the BSC.
Mallory loves to read, write, and illustrate her books. She one day wants to be an author for kids. Her story won "Best Original Fiction" of the sixth grade in Mallory on Strike.
She leaves the BSC to go to Boarding school.
Mallory has seven younger brothers and sisters. Because of all the children, The Pikes are a frequent client of the Baby-sitters Club.
Mallory likes Ben Hobart. They go to the Valentine's dance together in Stacey's Ex-Best Friend, even though they had been fighting at the time1. Mallory's best friend is Jessi Ramsey. Sometimes Jessi and Mallory pretend they are horses2.
