Up in Docking Bay 13, Sheridan and Ivanova are marveling at Kosh's ship. "They must be at least a thousand years ahead of us." Sheridan says, and tries to go closer, but is driven back by some kind of defense system. Before they can do anything else, Garibaldi shows up with news.
As they leave, Kosh appears and the ship presents a message on its side to him.
An alert has gone out that Dr. Everett Jacobs, the president's former physician is now a fugitive. He is said to have stolen information and has apparently come to Babylon 5. An Agent Cranston from Earthforce arrives to conduct a search for him, and Sheridan agrees to cooperate.
Dr. Franklin, who is Jacobs' former student, protests that Jacobs was a humanitarian and wouldn't do something like this, but Garibaldi isn't so sure.
In the meantime, Dr. Jacobs is wandering through the Zocalo trying to get an Identicard, but the merchants refuse to sell him one when they see how desperate he is and figure he must be on the run.
Sheridan runs into Kosh in a corridor and asks him about the dream he had a while back. Kosh's response is as enigmatic as ever:
- Kosh: I sought understanding. I listened to the song. Your thoughts became the song.
Sheridan: Has this ever happened before?
Later as he and Garibaldi are reviewing the search patterns that will be used, Sheridan notices a ribbon on a wall and hastily leaves. A short time later he meets with an envoy of General Hague (Sarah) in a dark corridor. She informs him that Dr. Jacobs does not have stolen information, he has information that then Vice-President Clark did not have a virus when he left Earth Force One, implying he knew it was going to explode. She then tells him they need to find Jacobs, get a statement from him and get him off station alive.
- Sheridan: Yeah, you want mayo on that?
He runs off to inform Garibaldi.
Later, Garibaldi sends a secret message to Franklin telling him to meet him at his place. He intends to go looking for the doctor and wants Franklin to come along. He takes a couple of guns and puts on a fedora, calling it a "clever disguise".
Jacobs, in the meantime, has fallen into the hands of some unsavory characters who find his official pocketwatch and figure he must be worth something to someone.
Sheridan is dealing with Cranston, and manages to send him on a wild goose chase giving Garibaldi and Franklin some breathing room. He suddenly gets notice that Ambassador Kosh wants to see him.
Franklin and Garibaldi haven't been having much success until Garibaldi notices a merchant trying to sell Jacobs' watch. He intimidates the man into telling him where he got it and he and Franklin are able to find Jacobs that way.
In Kosh's quarters, Sheridan tries to find out why the Vorlon wants to see him, but after several attempts, Kosh, seemingly disappointed, dismisses him. Sheridan gets irritated and demands to know what he wants, prompting a strong response from the Vorlon: "Never ask that question!" Eventually, Kosh says he will teach Sheridan.
- Sheridan: About yourself?
Kosh: About you. Until you are ready.
Sheridan: For what?
Kosh To fight legends.
The crew manage to rescue Jacobs from his captors, but now they have another problem. Cranston is about to conduct a full sweep of the station for the tracking implant Jacobs has. They need to get him off the station now, but all the docking bays are covered. All except one, Sheridan realizes.
Later, Cranston is with Sheridan and Ivanova in C&C as they activate the sweep. Moments before, Kosh's ship is granted clearance to leave. The scanner sweep runs down the length of the station and reveals...nothing. Cranston is not happy, and as Kosh's ship requests permission to jump out, he demands it be scanned first. The scan turns up one lifesign, not human. Sheridan points out that they could order it back and search it, but that would create a terrible diplomatic incident. Cranston lets it go.
After Cranston and his posse leave to pursue other leads — many of them handily provided by the B5 command staff — the ship comes back; the command staff meet it in the docking bay. Sheridan explains that the ship itself is alive, and that this was what the sensors detected. After a few moments, it opens and takes out a comatose Dr. Jacobs. Franklin wakes him up and Dr. Jacobs looks up at the ship in wonder, saying it sang to him.
Sheridan meets with Sarah again, and gives her the data crystal that has Jacobs' readings on it. She thanks him and promises to get Jacobs off station as quickly as possible. As for the data crystal, it isn't enough evidence to use against President Clark — yet — but it's a start.
This episode contains examples of:
- All Your Base Are Belong to Us: Cranston essentially hijacks Babylon 5 to search for Dr. Jacobs
- Berserk Button: Kosh doesn't respond when Sheridan goes on a tirade but responds, somewhat angrily, when Sheridan asks him "What do you want".
- When Garibaldi asks Max to hand him the data crystal, the latter tries to deny knowledge of it. Garibaldi responds by shooting the floor and wall around Max, telling him You Wouldn't Like Me When I'm Angry.
- The Chessmaster: Sheridan shows himself to be quite a good one in this episode.
- Chekhov's Gun: Kosh's transport.
- Cloak & Dagger: A lot of it going around. Sheridan has a secret meeting with an unnamed agent of General Hague, signified by a red bow tied to a non-descript area of the station. Clark and his cohorts are trying to silence Dr Jacobs because He Knows Too Much.
- Continuity Nod: Garibaldi is skeptical of Jacobs despite Franklin vouching for him, reminding him what happened the last time one of his old colleagues came on board.
- Dark Secret: Dr. Jacobs has information that then Vice-President Clark was not ill when he left Earth Force One, implying that he knew it was going to explode.
- Kosh doesn't like being asked, "What do you want?"
- In addition, Dr. Jacobs' habit of using stims to stay awake suggests that he may have taught Dr. Franklin some things not on the curriculum.
- Jerkass: Cranston
- Cranston, again. He was in C & C with Sheridan and Ivanova when Corwin repeatedly tells them that Ambassador Kosh's ship is launching out of the docking bay, and yet when Kosh's ship is about to enter the jumpgate, Cranston reacts angrily that he wasn't notified about a launch (despite him being right there hearing all about the launch from the get go).
- Freeze-Frame Bonus: In-universe. Garibaldi's actual message to Franklin, hidden in a visual transmission where he wishes Franklin a happy birthday (it isn't actually Franklin's birthday), is a pair of speech bubbles in a single frame of that transmission.
- He Knows Too Much: When your personal physician, who knows one of your biggest secrets, decides to go public...
- I Don't Think That's Such a Good Idea: Franklin's reaction to Garibaldi's disguise and idea to go hunting for Dr Jacobs' on their own, asking rhetorically "why is my life suddenly flashing" before my eyes".
- Living Ship: Kosh's Vorlon transport.
- Never Say That Again: When Sheridan asks Kosh "What do you want?", Kosh replies "Never ask that question."
- Paper-Thin Disguise: Garibaldi puts a fedora on and calls it a disguise, also noting that many of Downbelow's residents don't notice his face as much as his badge.
- The Professor: Jacobs was one of Franklin's teachers.
- Understatement: Sheridan unknowingly makes a pretty huge one when he speculates the Vorlons "must be at least a thousand years ahead of us." It's the Minbari that are about a thousand years ahead of humanity. The Vorlons are more like a billion.
- You Didn't Ask: Part of Ivanova's reasons to Cranston why no one mentioned they might be able to use the station's internal sensors to speed up the search.
