The space station is still reeling from the revelation of Kosh's true shape. A ranger, Marcus Cole, arrives to the station, having narrowly escaped from a warzone. The station is visited by a representative of the Earth Force Special Intelligence division, he wishes to find out more about the Shadows. The knowledge of it, isn't given him lightly, and a secret war council is formed as the threat of Shadows is a growing concern. Mollari is trying to break the pact with Mr Morden. It's proving more difficult than Londo naA vely thought it would be as he owes them.

A wave of seemingly random terrorist bombings spreads fear across the station. No known terrorist group is claiming responsibility, and people are scared. The hunt for those responsible of the bombs becomes top priority. Meanwhile, Lennier who was caught in one of the explosions fights for his life in the medical bay. A religious group wishes to move in to the station, and spread the teachings of their God and learn of other races' Gods. They are a highly educated group of followers, and means to spend 4-5 decades researching spirituality of other races.

There are extensive delays in the customs check-point, and people are angry. Sheridan manages to calm things down momentarily, but problems are piling up. G'Kar is to be replaced by another council member, a council formed by the Centauri. This measure to defuse G'Kar's attempt for a resistance movement. The Narn appointed is doing it out of pure fear for the continued killings, and means to try to stop them by cooperating with the Centaur. A mysterious alien probe is sweeping the station, making things even more stressful. The doctor is trying to keep the stress at bay, by taking stims.

The monks are settling in nicely at the station, and are making friends amongst the staff. The punishment where a mind is wiped clean and replaced with another personality, usually works. But it would appear that sometimes it doesn't work, one of the peaceful monks goes through a major transformation. Lyta Alexander returns from the Vorlon home world. She isn't allowed to talk about what she saw there, but she is clearly affected by her experience, improved even. She has returned to work for Ambassador Kosh.

The secret war counsil, containing the leaders of Babylon 5 and Delenn plans to seek out allies in a war with the Shadows, that they feel certain will take place. There are a race that are old and almost forgotten, The First Ones, old enemies of the Shadows and may prove to be difficult to approach. Draal, the guardian of the planet below, provides advice and help on their journey to find and negotiate with them. G'Kar is sensing there might be something of interest to him, fishing for information, and intends to be a part of it - not even knowing what it is. Beside not getting along with the Earth Force standard issue fashion, Zack is forced to help the new political officer that just arrived. This new position created, of course, being news to Sheridan and he's objecting vehemently.

The Nightwatch are taking a more agressive attitude in controlling expression of views and upholding codes of conduct. Things are a bit unstable after President Clark has been revealed as the man behind the murder of the former President Santiago. While the world awaits to hear if the proof of his guilt is correct, Bester is pursuing somebody he claims to be of danger to B5. A drug has been spread through the station, called dust and works as a telepathic conduit into somebody elses brain.

Alien parasites that attaches itself to humans and then controls them - has been brought onboard Babylon 5. Marcus has a wide array of contacts down below, and one of his most trusted ones doesn't show up. When going to look for him, it turns out that the contact has changed. When looking for another dear friend, that has gone missing, Marcus gets worried. Ivanova needs to find out if the newly appointed lieutenant David is to be trusted to be invited to partake in the secret alliance. David mistakes her interest as a romantic interlude.

Marcus shows Ivanova a lot of attention - to her dismay. When not courting Ivanova, Marcus has a tough and physical task of having to deal with the underworld. As the alliance continues relentlessly to collect evidence against President Clark, Garibaldi has asked Marcus to bring a woman over from Mars. The story she has to tell is very important. She has encountered Shadows, and the people involved are not to be trifled with. Her revelations forces Sheridan to make a rather shocking decision. G'Kar doesn't seem too affected by the experience of being in jail, and is spending his time writing a book. The Nightwatch continues to spy around the station and Zack is saddened by the prospect of having to make reports of his friends.

As the evidence that President Clark was responsible for the death of his predecessor mounts, the man takes a bold step and declares martial law, dissolving the Senate and reigning in the military. On Babylon 5, the Night Watch sympathisers are given power over security, much to Mr Garibaldi's righteous anger. Captain Sheridan has a plan, but it doesn't come without its own risks.

The citizens of Babylon 5 are leaving in droves since the martial law was put in place on the station. Things are getting hairy and few wants to be around when bad goes to worse. The Narns are helping out handling the security and don't miss an opportunity to make Londo's life a misery. Renegade ships fighting the current government finds their way to Babylon 5. Sheridan must decide on how to allow them on the station, without the Earth government finding out. Earth troups are finding themselves fighting eachother, they know everyone they kill and it's taking its toll on everybody. A seriously injured ranger is smuggled into the medical bay and he reports that the Shadows are moving, with many allies.

Following the breakaway from Earth, Delenn thinks that it would be a good time to hold a rebirth ceremony. Everyone else seems to be too busy. The Nightwatch have not chosen to go quietly into the night and kidnap Delenn, demanding that the station be returned to Earth jurisdiction. The kidnapping causes more than a few of the station's personnel to confront their inner fears.

One of the strengths of BABYLON 5 is the care with which all of the characters, including the more minor ones, have been detailed. Stephen Furst's Vir Cotto has been a comedy sidekick since the start of the show, but as with all the other characters he has been evolving and now we see what he has evolved into, a man of honour and courage despite his outward appearance of fear and ineptitude.

King Arthur walking onto a space station in the far future. It's an idea that is utterly absurd, but the plot manages to take such a ridiculous idea and turn it into an affecting and occasionally touching episode. The man isn't Arthur, but it is the revelation of who he is and what happened that drove him to such a delusion is the core of the story.

ISN is back on the air, finally, but it is soon clear, that ISN isn't to be trusted as a news source anymore. What started as a hope for better circumstances, ends up being a proof that all is not right back on Earth. When Sheridan is out testing a new space ship - they pick up a distress signal. It comes from Bester, the Psi Corp leader. He claims he have information that may help them in their quest against the Shadows. Although not a person they'd normaly trust, Bester asks for an unprecedented collaboration. G'Kar is growing restless about not having been invited to the secret alliance yet and is forcing the issue.

The Shadows are not hiding anymore and are now attacking openly. Knowing that they are vulnerable to telepaths, the secret alliance now finally have a weapon of sorts. The trouble is to create a fleet big enough to take them on. Kosh is hardly around at all, and is a troublesome sign. Adira is back, the exotic dancer that managed to catch Londo's heart. Mr Morden moves about the station, with his ever present Shadows. They're not happy with Londo not wanting to have anything to do with them. Worlds previously aided by the Shadows now find themselves on the receiving end of violence. Sheridan struggles to unite all races in a war against the Shadows, but internal quarreling and fear of the Shadows makes it very difficult. Dr Franklin handles the stress by taking too many sims, and it's starting to affect his work.

Commander Sinclair receives a mysterious letter, kept by the priest cast for nine hundred years to be delivered at a specific day and time. Messages from the past or future, Babylon 4 in a temperal flux - there are mysteries to solve and Sinclair, now ambassador, is the key. He returns to Babylon 5 meaning to set everything right. Delenn received a letter too, and plays a significant role in past, present and future. The planet below is finally fulfilling its purpose and our heroes are shown what they've already done and now must do.

With Sheridan, trapped in time with a future emperor Londo, and a Centauri in burning ruins, Sinclair, Delenn, Ivanova and Marcus are on Babylon 4, trying to set in motion what has already been seen. Knowing, that in eight days they'd be destroyed by the Shadows, invigorated and with a lot larger fleet than if they don't manage to change the past. The staff of Babylon 4 has no idea of the purpose of their presence and doesn't make it easier for them. The future Londo has a startling revelation, and isn't perhaps as hateful and filled with thoughts of vengeance as he first let on.

Dr Franklin has taken a personal leave of abscence. His abuse of stims have pushed him to a limit where he's lost control. He has left his normal life to pick up the pieces, and try to find himself. Lyta Alexander is heart broken to hear about Kosh's death. A new ambassador of the Vorlons is sent to the station, and he is to be called Kosh as well. He's no less enigmatic, than his predecessor. Sheridan decides to test and see if their theory of having a way to beat the Shadows will work - and he needs Lyta's help to succeed. The Narn fleet is slowly getting back together, although heavily damaged.

Delenn is to become the next head of the Rangers, now that Sinclair isn't there anymore. She gets unexpected competition for the job, though. A maintenance worker disappears suddenly, and once Garibaldi starts digging - it would appear that a whole section of the station is missing. Ivanova is out looking for Dr Franklin - as he's needed to try and get hold of more telepaths to help fight the Shadows. He's suffering from stim-withdrawal syndrome and needs to take his time getting back.

As a group of religious leaders visits Babylon 5 with important news as to what is happening on Earth, Sheridan finally figures out what the Shadows are planning and Delenn shows him the forces that he will have at his command. Ambassador Mollari brings to fruition a plan to destroy his rival Lord Refa by luring G'Kar to Narn into a trap.

The station is expecting the Shadows making an attack at any moment. The war council are having troubles trusting the leaders, not being able to say clearly what the plans are in fear of it reaching the wrong people. Ivanova and Marcus are sent out to scout, to be able to give an advance notice on when the enemy turns up. The plan that has been worked out, depends on the station knowing exactly when they arrive. Dr Franklin is still on a walk-about, and his expertise is going to be needed.

Delenn and Sheridan are growing closer , and are going through a Minbari tradition where the woman sit and watches the man sleep for three nights to see his true self. In the midst of this - John's wife suddenly turns up. Anna - that died on Z'ha'dum several years earlier, has come to take Sheridan there. Sheridan goes through an emotional roller-coaster, and Delenn is on the receiving end. Having been warned about going to Z'ha'dum by Kosh, it's a difficult decision for him to make. Londo receives a warning from one of Mr Morden's associates - leave the station, or he may die.
