Bod is adopted by Mr. Owens and Mrs. Owens, since his parents can’t take care of him anymore.Mrs. Owens sees it as her duty to take care of Bod, even though the other graveyard residents are against it.
Silas, the vampire, encourages Mrs. Owens to keep the toddler in the graveyard. He offers his help to raise Bod. Silas became the guardian and mentor of Bod. He is the only graveyard member who answers all of Bod’s questions patiently about why Bod is not allowed to leave the graveyard. He also takes the education of Bod very serious.
After Silas has to leave for a while, Miss Lupescu takes care of Bod as a substitute guardian. She is focused on disciplining Bod, which Silas probably didn’t do. Miss Lupescu is sincere about teaching Bod the dangers of the world outside of the graveyard. Even if Bod has a difficult time and doesn’t see any value in the teachings of Miss Lupescu, he still learns important lessons, which guide him on his future journeys.
