Babylon 5, Season 2: The Coming of Shadows

[last lines of the season]

Susan Ivanova:
It was the end of the Earth year 2259, and the war was upon us. As anticipated, a few days after the Earth-Centauri treaty was announced, the Centauri widened their war to include many of the Non-Aligned Worlds. And there was another war brewing closer to home. A personal one whose cost would be higher than any of us could imagine. We came to this place because Babylon 5 was our last, best hope for peace. By the end of 2259, we knew that it had failed. But in so doing, it became something greater. As the war expanded, it became our last, best hope for victory. Because sometimes peace is another word for surrender…and because secrets have a way of getting out.

Newscaster:
When our ship encountered a distress beacon attached to an EarthForce recording device, these images, released exclusively to ISN, were found on that recording. Strategic analysts in Earth Dome have indicated they don't know who this new race might be, but promise to find out.
