The Girl Who Played With Fire
How we cite our quotes:
After Salander's nighttime visit to his apartment [Bjurman] had felt paralyzed – thoroughly incapable of clear thought or decisive action. He had locked himself in [and] did not answer the telephone […]. (2.15)
This refers to an event from Tattoo. A week after Bjurman brutally rapes Salander repeatedly over an eight hour period, she comes back in the night to return the favor, in a manner of speaking. Since then, he's learned the true meaning of isolation.
Mimmi: "Check it out […]. That guy over there is Mikael Blomkvist. He was more famous than a rock star after the Wennerström affair." (9.93)
On the surface, Blomkvist is the anti-isolation to Salander's isolation, which is part of why she feels so isolated from him. He embraces so many people, and she doesn't feel there's room for her. Of course, he's far from immune to the sting of losing her, of being isolated from her.
He had tried to reach her every day since then. […] He was beginning to despair. (11.12)
After he witnesses her being attacked in the botched kidnapping, he can't deal with being isolated from her. Not only is he worried about her, but seeing her in action brings forth his intense feelings for her.
