Sheridan decides to test the theory that telepaths can harm Shadow vessels. Lyta Alexander accompanies Sheridan on this mission, but no other members of the Alliance outside of the Minbari offer to help. Garibaldi confronts G'Kar about the lack of support from the Narns, especially in light of the risks the entire Earth crew has taken in helping and sheltering the Narns. G'Kar is able to not only convince the Narns to throw in with their support, but the other races as well.
The replacement Vorlon is introduced, whose name is never revealed but was later identified by JMS as "Ulkesh". This Vorlon is darker and somewhat more amoral than the previous Kosh and regards humanity with more disdain than his predecessor. Kosh and Ulkesh have also appeared to Delenn years before aboard the Grey Council ship as they lived inside Dukhat's sanctum in the Babylon 5 movie In The Beginning. Ulkesh is voiced by Kosh's voice actor and has a distinctly higher voice pitch than him. Also, the "chimes" that accompany Ulkesh's speech are somewhat darker. Even Ulkesh's overall color scheme seems darker than Kosh.
Lyta hears Kosh's voice while Sheridan is talking to her, hinting that a piece of him might have survived inside of Sheridan.
It is proven that Shadow ships are vulnerable to telepaths, although it requires tremendous focus and power on the part of the telepaths to effectively jam them. Lyta was almost driven insane by the Shadow ship when she initially tried, but after learning of how the Shadows killed Kosh, she angrily lashes out at the enemy vessel and manages to "trap" it inside her mind and prevent it from moving.
The G'Tok, the Narn warship which was granted sanctuary by Sheridan on "The Fall of Night", makes a return.
G'Kar reveals a strange discovery he has made - every race has its own version of what the humans call "Swedish meatballs." For the Narns, the name of the dish is "Breen" (it is unknown though if this is an absolute truth, and if it also applies to such beings as the First Ones, including the Vorlons and the Shadows).
G'Kar manages to rally many of the non-aligned worlds into helping Sheridan.
