Left for dead after the brutal murder of her family, during which she herself was assaulted, Henrietta suffered severe psychological trauma, making her suicidal. Like the other cyborg-girls, she was brainwashed into forgetting these events by a technique known as conditioning. Henrietta is devoted to her handler, Jose Croce, towards whom she has strong feelings. She even shows signs of jealousy when she feels Jose is paying attention to other women. He encourages her to share his interest in astronomy which she passes on to the other girls. Jose even gives her a diary, but this causes her distress when, as a result of the long-term effects of the conditioning, she begins to forget the events she noted in the book. She's killed by Jose in Chapter 83 as she euthanizes him as part of a suicide pact she had made with him while investigating Elsa's death. Henrietta's preferred weapons are the SIG Sauer P239 Two-Tone, the Fabrique Nationale P90 PDW, and the FN FAL. She and her handler have also used the Walther WA 2000 sniper rifle and Ingram MAC-10.
