Despite Lisbeth’s nearly total indifference to what others think of her, she is not impervious. When she falls in love with journalist Mikael Blomkvist (played by Michael Nyqvist) she is so afraid of being ridiculed for her feelings, especially after she realizes that he only sees her as a friend and occasional sex partner, that she takes off on a year-long trip. Even after he has saved her life and helped secure her freedom, she refuses to see or speak to him until her “foolish” feelings of romantic love are gone. Then can she be friends with him again. Which suggests that the ridicule Lisbeth fears comes from a harsh inner critic and is more about how she appears to herself than to Blomkvist; but this doesn’t seem to occur to her.
The last we see of Lisbeth, she is either shutting the door on Blomkvist but saying she will “see him later” (in the film), or allowing him to invite himself in for coffee (in the book). In both cases Blomkvist is relieved to have her friendship again, and Lisbeth is relieved that she only wants him as a friend.
Off the top of my head I can think of two righteous avengers who find something better on the other side of revenge – Clint Eastwood in The Outlaw Josey Wales, and Simon Baker as Patrick Jane in TV’s The Mentalist. Once the scales are back in balance (the eye for an eye) and justice restored, the character (and the society they are part of) can begin to heal.
Eastwood’s Josey Wales finds love and community in an idyllic Western landscape of mountains, forests, and rivers, living in harmony with the indigenous people and the land. Baker’s Patrick Jane finally hooks up with former boss Teresa Lisbon and plans to rebuild a house so ramshackle it has no keys – like a child’s treehouse – in another idyllic setting, while family and co-workers dance ecstatically at their wedding. In both stories there is a sense of innocence regained or discovered, even if only momentarily — innocence achieved.
In the Millenium trilogy the society is saved, a hidden canker revealed and cut out – but what Lisbeth Salander might do with her life is unclear. She has been saved from death and prison, her rights have been restored, and she has piles of money. So what now?
