Johanna (character)

Anthony Hope falls in love with her at first sight and vows to rescue her from her containment. Judge Turpin discovers her plot to escape and sends her to Fogg's Asylum for the mentally deranged. She is rescued by Anthony, posing as a wig maker's apprentice. During the escape, she is forced to kill Fogg, the Asylum owner, when Anthony cannot bring himself to. Disguised as a sailor, she is taken to Sweeney Todd's barber shop, where he has been longing to see her. When an insane beggar woman (later revealed to be her mother) pursues her in the upper room, Johanna hides herself in a large trunk. From there she presumably witnesses Todd's murders of the Beggar Woman and the Judge. She is nearly murdered by her father when he discovers her, as he does not recognize her as his daughter (being as he had never met her since infancy and because she is disguised as a young man). She survives when Mrs. Lovett screams in the basement bakehouse, distracting Todd and allowing her to escape. In the final scene, Johanna, Anthony and two policemen encounter Toby in the bakehouse, mindlessly turning the meat grinder, surrounded by the corpses of Todd, Lucy, Mrs. Lovett, and Turpin. Presumably she elopes with Anthony after the events of the show.
