Booth and Brennan investigate the mysterious death of a surgeon whose life and death challenge Brennan's legendary objectivity.
As the team sifts through the evidence, Brennan identifies more and more with the brilliant doctor and her life.
Which, in turn, makes her question some of her own choices.
Could she end up like the doctor in the photo, someone who disappeared and no one knew or cared?
As time goes on, Brennan keeps on seeing the victim as herself. The voice of the doctor sounds like her as well.
When Temperance discovers that the victim died with heroin on her person, she leaps to her defense.
What this does is allow her to see her life from another perspective, and she doesn't like what she sees.
We see very little of the other cast members, but the writing and acting keep our attention riveted to the screen.
Only Micah, the nighttime security guard, seems to get through to her. Like a figment of her imagination almost, he can talk about what’s troubling her.
Brennan finally acknowledges the signals that Booth had been sending her. When he responds, he says he's with Hannah, end of story. She cries.
