She returns to the station in late 2259, where she reveals Talia Winters as an unwitting mole for secret forces in EarthGov and Psi Corps.

[4] In season 4, Lyta is key to the eventual resolution of the Shadow War on Coriana 6, serving as the vessel through which Sheridan and Delenn confront the elder races and forces them to leave the galaxy.

Using unknown abilities and implanted instructions from the Vorlons, she triggers the destruction of the planet to spite Alfred Bester and prevents Shadow technology from falling into the wrong hands.

[7] In season 5, Alexander becomes romantically involved with Byron, revealing to the telepaths that they had been created by the Vorlons as weapons for their war with the Shadows.

After Byron's death, Alexander gets inspired by his cause to create a homeworld for telepaths, and becomes the leader of a movement sponsoring violent resistance against the Corps.

It is strongly implied in Crusade and some of the canonical novels that her actions (both on Babylon 5 in 2262 and afterward) led to the Telepath War of the mid-2260s, in which she was killed.

According to Straczynski,[13] Lyta was intended to appear in the Crusade episode "The Path of Sorrows" as part of a flashback, but Tallman's salary negotiations failed.

In the aforementioned script book, Straczynski wrote that both Lyta and Lennier were killed in the explosion of Psi Corps Headquarters in a major battle of the Telepath War.
