Rathenn uses a triluminary to restore Sinclair's memories of the Battle of the Line - how he was captured by the Minbari, interrogated and tortured and finally released.  He is told about the Minbari souls being reborn in humans, and that he has such a soul.  It was agreed between Earth and the Minbari that the secret would not be revealed for fear of reprisals from both sides.  And it was with EarthGov's permission that Sinclair's memory of the event be wiped.

Sinclair is to be taken "home" - to Minbar, as Earth Ambassador.  With an angry and distrustful warrior caste member watching his every move, he is taken to meet the Grey Council, where he will read them an excerpt from Tennyson's Ulysses in the hope they will understand.

On Minbar during preparations for the ceremony, Sinclair contacts Garibaldi to apologize for not being able to say goodbye, and learns that Delenn has departed for Minbar.  He meets her, shocked at her change of appearance, before he is accused of a plot to assassinate the newly chosen Leader: a high-powered weapon and plans were found in his luggage aboard Delenn's ship.  If he is convicted, there is certain to be war against the humans and the Minbari once more.

Colby plans to kill Talia Winters as she could expose him as the one who attempted to kill Hall.  He is contacted by his superior, Webster, and he pleads to be taken off Babylon 5.  Talia evades him, and she agrees to Sheridan's request to scan Hall's mind to find answers to their dilemma.  Colonel Rabock has arrived early, so she has to make it quick.

Hall is an undercover agent for Psi Corps, infiltrating a group who call themselves "Homers", an action group against the increasing alien influences on human society.  They are aboard the Chiyoda-Ku celebrating the death of "that Minbari stooge" Santiago - and one of them mentions a plot in motion to kill the new Minbari Chosen One.  Hall tries to get a warning to the Minbari but is discovered and a firefight ensues.  After a distress signal is sent from the ship, Hall is forced to asphyxiate the crew to save his own life, and he is on the verge of death when the Babylon 5 Starfuries arrive.  After the attempt on his life he sought out the resident telepath.

Garibaldi finds a video record of Colby smuggling the weapon's package onto Delenn's shuttle.  Delenn interrupts Sinclair's trial to present the new evidence.  Neroon refuses to be moved, even when Delenn reminds him that a renewed war with the humans will still cause great sufferance to Minbari souls.

Colby ambushes Webster, still posing as Colonel Rabock, and gets him back onto his shuttle along with Hall's body.  Colby discovers that Webster himself is really Cypher - and Colby fires his weapon at the shuttle's systems, destroying it before Babylon 5's Starfuries can recapture them.

Neroon is determined that even though Sinclair may not be entirely guilty of the plot, this act against the Minbari is just cause enough to declare war.  The tribunal agrees, but Sinclair, according to an ancient Minbari custom, is prepared to sacrifice his own life in exchange for war.  The new Minbari Leader is impressed with Sinclair's willingness to pay the ultimate price for peace and exonerates him.  Delenn congratulates Sinclair on his plot: he knew full well that the Leader would not have allowed Sinclair to die because he holds a Minbari soul.
