Babylon 4 reappears at the same place it disappeared four years before, and Sinclair and Garibaldi lead an expedition to evacuate its crew. Meanwhile, Delenn is summoned by the Grey council. They inform her that they have selected a new leader - her.

Ivanova gets a distress call from herself pleading for help as the Shadows destroy Babylon 5. It is dated eight days into the future. At the same time, on Minbar, Sinclair is given a nine-hundred-year-old letter from Valen, telling him that a drastic action must be taken to prevent that future.

While Sheridan is unstuck in time, seeing a glimpse of a future Centauri Prime in ruins, the others continue with their plan to take Babylon 4 back in time.
