While arranging the dead Minbari's burial, Delenn discovers that he and Ashan are from the same clan and sends Lennier to look for Ashan.

Plus, Morden's revelation in Day Of The Dead comes true with Lennier betraying the Rangers.

The series left Lennier's final fate unknown, although most of Morden's prophecies came true and there are hints in the series finale " Sleeping in Light " ( during a sequence when the guests were remembering their fallen friends ), that Lennier was killed in the Telepath War.

Gajic and Jinxo go to Delenn and Lennier and to Ambassador Londo Mollari and Vir, neither delegation can help him to find the Grail.

Londo has taken Lennier to a club with exotic dancers, and narrowly avoids giving Lennier an alcoholic drink, which reacts badly with the Minbari physiology.

Commander Sinclair confronts Lennier and Londo, Lennier takes the blame, and both are excused because of diplomatic immunity, although they are convinced to financially compensate for the damage caused.

* Lennier and Londo visit the ' Dark Star ' lounge / club.

In the course of the discussion, Londo reveals that Minbari sometimes do lie, but only when it is saving the honor of another ( as Lennier did for Londo in The Quality of Mercy ).

In a secondary plotline, Delenn, the Minbari Ambassador to Babylon 5 and Sheridan's lover, hears from her aide Lennier that Ambassdor Londo Mollari of the Centauri is holding a closed session of the Babylon 5 council.

The dead return for one night during a mysterious Brakiri religious festival: Garibaldi is visited by a ground pounder, Dodger, with whom he almost had a romantic fling three years ago ( see Gropos ), Londo cherishes a night with his lost love Adira Tyree ( see Interludes and Examinations ), Lennier tolerates the Shadows ' associate Mr. Morden, and Captain Lochley is visited by her friend for whose death she feels responsible.

" Garibaldi remembers G ' Kar, Vir remembers Londo, Delenn remembers Lennier, and Franklin and Ivanova remember Marcus.

Londo is very appreciative of his friends and reluctantly tolerant of insincerity ; he often chooses the friendship of people with temperaments similar to his own, but with personalities suited towards brutal honesty ( Michael Garibaldi ), or sincere naivety ( Lennier, Vir Cotto ).

However, in " War Without End ", Lennier states that the White Star is a living ship, and learns from each battle, thus removing this inconsistency.

However, in the season 5 episode " The Fall of Centauri Prime ", Delenn ( while talking to Lennier about themselves drifting in hyperspace ) appears to refer obliquely to the events of this film by pondering, " Who knows what's out there ; maybe we'll find a million-year-old jumpgate left over by the First Ones.

* Lennier explains to Brother Edward that the spiritual leader Valen is " a Minbari not born of Minbari ".

Sinclair asks Lennier for help, as Jha ' dur claimed she has been living with the Wind Swords, a branch of the Minbari warrior caste.

Lennier, representing the Minbari, votes " No ".

Sinclair confronts Lennier, claiming that the Minbari gave shelter to Jha ' dur.

* While talking with Gajic, Delenn and Lennier indicate for the first time that the warrior and religious castes of Minbari are often at odds.

Delenn takes a single White Star and travels to the Minbari homeworld with her aide Lennier to present Sheridan's proposal.

Delenn and Sheridan relocate to Minbar ; Lennier betrays Sheridan when an accident takes place on board the Minbari cruiser transporting him and Delenn to Minbar.

The Minbari characters of Delenn and Lennier figure prominently throughout the series ; Neroon, Draal, and Dukhat are less prominent Minbari characters.

Just as Delenn was an acolyte of Dukhat, Lennier was the faithful acolyte of Minbari Ambassador Delenn for five years.

Though other Minbari felt much animosity towards Sheridan, as they felt he'd acted dishonorably in destroying it, Lennier held no hard feelings, apparently understanding why Sheridan had done it.

Delenn speaks with actress Mira Furlan's normal Croatian accent ; most other Minbari have native-speaker accents for English ( for example, American for Lennier, British for Neroon ).

He is perhaps best known for his role as Will Robinson on the CBS science fiction television series Lost in Space ( 1965 – 1968 ), as well as for his role as ambassadorial aide Lennier in the syndicated series Babylon 5 ( 1994 – 1998 ).

Lennier, recognizing Morden, is unwilling to accept counsel from him, unable to see Morden as anything more than the Shadows ' emissary.

Having sent information requests to the ambassadors prior to his arrival, he is greeted as a very important guest, " Honored Seeker ", by Ambassador Delenn and her aide Lennier.

Lennier appears to be quite good at poker, but fails to grasp the subtleties of the game, meaning he is only winning modest amounts rather than large amounts.

* The question Delenn asks Kosh through Lennier, to which the answer is " Yes ," is revealed in Season Two.

* Lennier confesses to Marcus that he is in love with Delenn, even though he knows that she will never return that love.

Lennier has told Dr Franklin that he is breaking protocol, but Delenn is in trouble.

When Lennier returns with proof that the Centauri Republic is behind the sneak attacks on shipping from many different worlds, the Interstellar Alliance holds a hearing to see Lennier's evidence.

Her aide Lennier calls her " Satai ," when he first comes aboard, indicating that she is one of the leaders of the Grey Council, but Delenn chooses to keep this information quiet.

Lennier is a character in the fictional universe of the science-fiction television series Babylon 5, played by Bill Mumy.

In the episode " Day of the Dead ," Lennier is confronted by the ghost of Morden, the human who worked with the Shadows.

Just before he leaves at the coming of the morning, he delivers one of the most important messages of the night: Lennier will betray the Rangers.

Lennier replies that it was one of their more militant warrior groups that took her in and that his government had no knowledge of their actions until recently, and now wants to keep that embarrassing fact secret.

A series of random bombings threaten the station, with one explosion seriously injuring Lennier.

They are physically stronger than humans, as demonstrated by Lennier lifting a human male by the neck with one arm in one episode.

Morden predicts that Lennier will one day betray the Rangers.
