Complete story — includes the ending
Bell, in possession of Olivia's body, promises that no harm will come to her and he will leave it after finding a suitable host. The Fringe team tracks down an apparently immortal woman, Dana with the help of an FBI agent, Lincoln Lee. Walter and Bell believe the immortality may be due to Dana having been struck by lightning twice before. They find that Dana is attempting to connect to the souls of suicidal people, hoping that she can die with them and "stow away" with their soul to heaven to rejoin those of her family that were killed in a burglary attempt. They are able to prevent Dana from using a bomb set to destroy a commuter train. Instead, when she leaves the train with the bomb, the bomb explodes and she finally dies. As Bell discusses the potential theological implications with Peter, a church bell ringing nearby brings about Olivia's personality temporarily, and Bell realizes his possession of her body may be more difficult than he thought.
