After the end of the Shadow War (but before the events of
Babylon 5: The Lost Tales), President John Sheridan and Delenn leave Babylon 5 for Minbar to further develop the Interstellar Alliance. While participating in the opening of an advanced power station, John begins to feel poorly and learns the power plant uses tachyons. As in "War Without End", John becomes unstuck in time and space. John jumps 23 years into the future to see an older Dr. Stephen Franklin. John died three years prior, but Stephen does not have the heart to tell him, and instead claims that John is 18 years in the future. Stephen's tests prove that Sheridan is out of phase in time and can end up in alternate realities. Stephen formulates a plan: find Zathras and obtain a time stabilizer. Before anything can be done, John jumps into the past. John finds himself on Earth in the year he took over B5, at his parents' farm with his father. As he enjoys the scenery, he jumps to Z'ha'dum in 2256 during the ill-fated expedition of the
Icarus and the awakening of the Shadows. John attempts to warn the expedition not to tamper with the aliens in hibernation, but is too late. The Shadows awaken and attack the expedition crew. John jumps to an alternate timeline where he never commanded B5. The Shadows are overrunning B5 and John meets Commander Jeffrey Sinclair, quickly explaining what is happening to him. Jeffrey drafts John to make a last stand against the Shadows. Both John and Jeffrey agree that B5 is lost and the only way to save the evacuating populace of the station is to stop the Shadows by destroying B5. As John struggles to blow up B5's power core he encounters Lyta and G'Kar. John jumps before he can destroy the station, but Lyta and G'Kar complete the process. The station's explosion destroys the invasion force, saving the escape shuttles. John finds himself aboard B5 in his correct time in Captain Elizabeth Lochley's bedroom. John convinces Elizabeth to shuttle John to Epsilon 3 to speak with Zathras. Zathras determines that John's shifting through time and space risks creating a dimensional collapse event, where all timelines will fall upon each other. Before Zathras can stabilize John, he jumps again. John finds himself in a city on Earth in a reality where the Shadows are victorious. John finds Susan Ivanova and Londo Mollari resigned to the destruction of Earth. After losing the Shadow War, the Vorlons do not want the Shadows to have Earth and intend to destroy it by pushing the moon into the planet. As the moon descends, John jumps once more and finds himself at The Rim, the edge of space, time, and reality. He meets an entity that takes the form of G'Kar, explaining John is a threat to reality. John questions the point of his existence if he is so dangerous, but the entity explains that destroying John would defeat the great experiment of consciousness. The entity tells John that possibility is based on love and its greatness cannot be so easily destroyed. John wants to ask more questions, but jumps again. John finds himself in a reality in which the
Icarus expedition never happened and his younger self has peacefully commanded B5. John talks with his younger self and tries to explain his situation. After Lyta telepathically confirms his story, Zathras arrives to help John. When John starts to jump again, Zathras reminds him that he has influence over where he jumps based on his feelings and he thinks of Delenn. A portal opens, revealing that Delenn has been chasing after John the whole time. John joins hands with her and returns home. ==Cast==
