The Ending Of Interview With The Vampire Season 1 Explained

Just as ruthless and calculating as Lestat, Claudia is a fascinating character. Like Lestat, she wasn't given a choice in becoming a vampire, and her turning is all the crueler because of her age. She develops mentally and emotionally into a seasoned killer and a fully realized woman, but her physical form remains stuck in adolescence. 

Whereas her companions can blend in among men, Claudia is forever regulated to an inferior status in society because she's a child. Nothing changes in her body over the decades, and in Episode 4, her diary entry rails against her "flat-chested, hairless-crotched ... baby doll body." It doesn't help that Lestat is naturally withholding and Louis doesn't know enough to share with her, so she's kept sheltered like a little girl as well. 

This inexperience and naiveté costs her dearly, but by the end of Season 1, she seems to be fully in charge of her life. She's angry and frustrated with Louis for his continued submission to Lestat, and all that's left of her in Louis and Daniel's present are her exhaustive diaries, which Louis maintains like priceless relics. It's unclear where she goes or what her fate is, but given that Louis has excised certain events from her records and only wants her shown in the most favorable light, her vengeful actions in Episode 7 will likely catch up to her. Claudia isn't a girl who goes down without a fight, though, and she's learned to outsmart even Lestat. So what could possibly bring her down?
