Vault 101's resident gossip hound, she has her nose in everyone's business. Of course, like all true gossips, she will vehemently deny that she is ever involved in the affairs of others. She is best friends with Pepper Gomez and is interested in Mister Brotch. She also keeps up the gossip with her married sisters, Mary Kendall and Gloria Mack.
Her hobbies include reading Tarot cards and writing poems. At one time, she attempted to write a poem in commemoration of the first overseer on Founder's Day. However, she suffered writer's block when she couldn't find a word that rhymed with "overseer". This is one of the few occasions Beatrice reuses one of her older poems.
She used to regularly post a notice on the Bulletin Board in the Cafeteria advertising her services as a fortune-teller. She divines the questioner's fortune by reading tarot cards. On July 13, 2268, she gave the Lone Wanderer a poem for their tenth birthday party.
On the Overseer's terminal in the Vault 101 Atrium, there are security dossiers on several people that live in the Vault. Beatrice's dossier describes her as "an absent-minded, sexually repressed sycophant." The overseer states that he wishes to talk to "our good doctor" about a "long-term pharmaceutical solution."
Despite her normally cheerful attitude, the poem she gives the Lone Wanderer is dark and depressing.
Upon leaving the Lone Wanderer's tenth birthday, Beatrice will follow the player, attempting to give them the poem. She will even follow down to the reactor level unless the player talks to Jonas.
Beatrice adopted Steve Armstrong with her own father acting as Steve's father.
