"All Alone in the Night" is an episode from the second season of the science-fiction television series Babylon 5.
Meanwhile, Ambassador Delenn is summoned by the Grey Council to decide her fate. Although a member of the Council, her decision to undergo the physical change into a half-human, half-Minbari hybrid has stirred strong feelings against her on the Council and in Minbari society. Fearing that she will be punished by the Council and not allowed to return to Babylon 5, she tells her loyal aide Lennier that she has never felt so alone. However, Lennier assures her that all will be well and insists on accompanying her on her trip. When she meets with the Council, they ridicule her physical change, but Delenn offers a passionate defense of her actions. However, the Council votes to remove her membership on the Council. She is replaced by Neroon of the Minbari warrior caste, giving the warrior caste four members on the nine-member council and disrupting the balance between the three castes (worker, warrior, and religious) that had existed for a thousand years. The Council tells her that she may return as Ambassador to Babylon 5, but they also make it clear that they now regard her status as ambassador as a joke and no longer take her seriously.
While traveling back to Babylon 5 Delenn intercepts messages from the station concerning Sheridan's disappearance. She identifies his captors as the Streib, a reclusive but advanced alien race who kidnap members of other races and experiment with them to determine their strengths and weaknesses (an apparent allusion to author/abductee Whitley Strieber). She offers to lead the Agamemnon and Babylon 5's fighters in a rescue mission. Sheridan and the Narn pilot manage to escape the Streib warship just after the Agamemnon and a squadron of fighters led by Commander Ivanova jump from hyperspace and attack the Streib vessel; it is subsequently destroyed. Back at Babylon 5 Sheridan finally meets with General Hague; Sheridan tells Hague that the command staff at B5 are loyal to Earth and are "good people". Hague then informs Sheridan of his belief that President Clark had President Santiago killed so he could take over the Earth Alliance; Hague also suggests the Psi Corps may be pulling the strings as well. He intends to expose Clark's conspiracy and he asks Sheridan to help him, Sheridan agrees. He also decides to ask his command staff for help in uncovering the conspiracy.
