The next day, St. John visits Jane to deliver news that she is twenty thousand pounds richer through the death of her Uncle John; but rewind, because first he has to go through her entire life story up to the part where Mr. Briggs contacts St. John in hopes of finding Jane. St. John suspects Jane is Jane Eyre, although she has always maintained an alias. Jane also learns that she is the cousin of St. John, Diana, and Mary, and is happier than twenty thousand pounds; she is willing to divide it between the four of them, though St. John thinks she’s out of her wits.
Mr. St. John wants Jane to follow him to India to serve as a Christian missionary, and to be his wife! She reluctantly relents to going with him to be a missionary, but not as his wife. He has a bad attitude about it. (That’s very unChristian.)
St. John is unyielding in his pursuit of Jane as his wife, but not for love, and she almost gives into his awesome power, because it is utterly spellbinding; yet, she thinks she hears Mr. Rochester call out her name, and she realizes that she must take care of unfinished business (Mr. Rochester) before or if she can move on.
Jane travels to Thornfield, but it is in absolute ruins; therefore, she must inquire at a nearby inn of what has happened to Thornfield and its inhabitants: Bertha Mason set the mansion on fire – you saw that coming - then jumped to her death, while Rochester was able to save his servants; unfortunately he suffered an injury and became blind. He is now living with two of his servants at Ferndean house.
Jane must go see Rochester at Ferndean, and Mary, the servant, lets her in. She enters the room where Rochester is: he hears her voice and thinks she is her ghost, but when he touches her, he embraces her and later asks her to marry him again, to which she obliges. He told her that a few nights ago he had called out to her, but Jane cannot bring herself to tell him that she actually heard him.
Mr. Rochester and Jane marry in a simple ceremony. Jane lovingly serves Mr. Rochester in aid of his blindness, and he regains sight in one eye. He is able to see his first-born son.
Jane is extremely happy in her marriage to Mr. Rochester, whereas they are as equals and truly live as one.
