Bell's ready to grab a Geiger counter and go -- much to Walter's excitement -- but Peter won't have it, saying they can handle it. He wants Bell to concentrate on getting out of Olivia's body so Peter can get back in, but Bell says the computer's searching the local hospitals for potential hosts based on their parameters, and he's not someone who can make that happen any faster -- but he is the only person in this universe with extensive experience in interdimensional decay. That's a great thing to put on a resumé, too. Peter backs off, sulking.
Over to... Hartford? All right. At an FBI office, a fax comes in with a set of fingerprints and a picture from the half-suicide/half-miracle the other night. The agent who takes it off the machine runs out to get Agent Lee, who's walking away from the camera to build up the reveal that we're finally going to get to see this universe's version of Lincoln Lee, who turns around, looking Clark Kent-handsome in his glasses that appear to be of the "my vision is perfect but I like how I look in these" variety. He looks at the fax. "Where is she?" he asks. "Boston," says the other agent. Wouldn't that information be on the fax? Maybe Lee needs real glasses.
Over in Roxbury, the Fringe team's checking out the convertiblized taxicab, with Bell saying they have more advanced molecular-degeneration-detection technology over there, but a radiation test should be enough to see if that's what's going on here. He's running the Geiger wand over the taxi, and Peter impatiently wants to know if he's found anything. He hasn't. "So if it's not the place, then it's got to be the girl. Must be something about her that allowed her to survive the fall," says Peter, which means Walter and Bell will get to work gathering DNA. Walter giddily points to his grumpy son that he and Belly are collecting human tissue and fluid specimens, just like when they were kids. "Glad you guys are enjoying yourself," says Peter, too mad to let anyone else be happy or to use grammar that befits his supposed genius-level IQ.
And Agent Lee shows up, with Broyles introducing him to the Bishops, telling them Lee has information regarding the case. Bell strolls over, and Broyles and the Bishops are awkward about introductions until Bell introduces himself as Olivia Dunham with Fringe Division. Lee's all, "What division?" but no one explains, so he tells him the woman who jumped and walked away is Dana Gray.
Showing them crime scene photos, he explains that Dana was murdered eighteen months ago with her husband and two children in a home invasion. "They ever find who did it?" asks Peter, instead of "Hold on, she took two bullets in the head eighteen months ago?" Lee says they did, and the guy was killed in a shootout with FBI agents, so case closed until Dana's body disappeared from the morgue. He thought it was stolen until -- he's got another set of police photographs -- he got a report of a double suicide, two people jumping out a dorm window, but when cops got there, there was one body. Two sets of fingerprints on the ledge, though, including Dana Gray's -- which is insane because she's dead, says Lee. "Well, you know, stranger things have happened," says Bell, nonchalantly. Amusingly, Lee says, "Um, no. They haven't." Peter tells Lee not to listen to him, which he hastily corrects to "her." Anyway, not knowing what else to do, Lee put Gray's fingerprints into the system, and over the next couple of months her prints were found at three other double suicides that turned out to be a single suicide by the time first-responders showed up. "I know this sounds insane, but I don't think this woman can die," says Lee. Walter leans over to Bell and says, "Isn't this our lucky day?"
I realize that Lee's an FBI agent, but considering the work they do you'd think the Fringe team would at least lock the door to the lab. Lincoln strides into the lab, and comes up short when he sees that there's an actual cow there. He calls out "hello?" and Astrid comes out to say "hello" and Peter comes out to say, "What's he doing here," like nice welcome, and Bell, back in his lab coat and working with Walter on dueling microscopes, says he invited him.
So Astrid introduces Lee to Gene, and Peter tells him that this is the place where the mysteries of the universe get answered. "And congratulations. Whatever your security clearance was, it just got about seven levels deeper," he adds. At what level of security clearance does the FBI start locking its doors, I wonder?
Anyway, Walter's got something to show them: they found two sets of DNA in the specimens they took from the scene. Really? In a cab? Congratulations on finding the cleanest cab in the history of ever. Anyway, they found something weird while conducting tests: the molecules of Gray's body didn't want to come apart; they're held together by an unusually strong electromagnetic bond. Lee actually raises his hand to ask a question: "You're saying that her body's being held together by magnetism?" Bell points out that everyone is held together by magnetism; our molecules are held together like these hematite rocks that just happen to be sitting there fortuitously for demonstration! "In Ms. Gray's case, the attraction was almost unbreakable. It's a miracle she left any blood behind at all," says Walter. "Miracle" or "plot hole"? Meanwhile, Bell's wrapping the hematite rocks into a bracelet around Astrid's wrist, and he says, "I think it suits you, dear." Thoroughly creeped out, Astrid thanks Bell but then removes the rocks and nervously buttons the top button of her blouse. Fortunately, she's not too unnerved by her increasing sexual harassment to ask how Dana got magnetically supercharged, and Walter wonders if she took the energy from the people she jumped with.
"Yeah, that'd make sense," says Bell. Yeah, that makes a LOT of sense. Bell takes it further: "She absconds with their life force at the moment of death." Lee, too polite to ask what everyone's been smoking, is all, "'Life force'? You mean like a soul? Is that even a scientific concept?" and Peter rolls his eyes and Bell lectures him on the evils of being "reductive," because every living thing is bundled energy, and maybe Gray has found a way to capture some vital portion of another person's essential energy and therefore has extended her own life. Lee, ignoring Bell's advice to not be reductive, skeptically says, "A soul vampire." Peter notes that in the file it said that each of the victims had already tried to commit suicide, so Bell figures Gray only wants to take the souls of those people that are already prepared to surrender their own. "A compassionate soul vampire," amends Lee, and Walter and Bell heartily agree. "Oh boy. Um, who are you guys?" asks Lee. Peter says he'll explain that on the way, and Lee didn't even realize they were going somewhere. "If you were looking for victims who had previously tried to commit suicide, where would you go?" asks Peter, and Lee suggests suicide hotlines and therapy groups, and Peter's all "Exactly." So... shouldn't you look a few of those up before you just jump in the car? Or are you planning to just drive down to Boston's suicide-hotline district?
Speaking of the compassionate soul vampire, a tearful Dana Gray kneels at the headstone where her 10-year-old daughter Kristin and 13-year-old son Eli are buried. She puts some fresh flowers in a vase, and then looks over at her husband Henry's grave.
Some time later, as she's leaving the cemetery, her cellphone rings. "Helpline. This is Joan." she says, sadness still in her voice. It's some downer named Brian who says he's going to hurt himself. "I guess you're in a bad place right now, huh?" she says, and he tells her that he's tired. She says lif
