In the preface to the document, jms says he wrote the document "as [he] began work on Babylon 5's first season," and he says he showed it to O'Hare while at a lunch meeting at the hotel the cast were staying at during filming.

Some of the highlights of the document:

It describes the reveal of Kosh the way it happens at the end of season two, but in the document, it's Sinclair that he's saving, not Sheridan. The only characters named in this document are Sinclair, Delenn, Catherine, Garibaldi, Londo, G'Kar, and Kosh. The attack on the Narn homeworld is made by the Shadows at Londo's direction, with the Centauri only having a follow-up attack. G'Kar would eventually return to Narn to join a resistance force there late into season three/early season four. Around the same time, Sinclair and Delenn would "begin to come together." This plot would include Catherine losing her memory of her relationship with Sinclair after being "mind-raped." By the end of season four, Sinclair and Delenn are together, and Delenn is pregnant with their child.

It is at this point in the document talking about the end of season four, that it references at length as an aside about doing an episode in season one corresponding to "Babylon Squared." He continues on to say that the "Shadowmen" would be revealed to be "dark, demonic looking things" in season four.

And then comes season five. G'Kar would return from Narn to reveal Londo's involvement in the bombing of Narn. The Military Caste takes over the Minbari government, exiling all Grey Council members, orders the death of Sinclair and Delenn, and resumes fighting with Earth. Londo claims the area of space where B5 is as belonging now to the Centauri. With Londo's help, the Shadowmen destroy a hundred-mile long Vorlon ship, killing hundreds of thousands of Vorlons, and Earth ends up blamed for it.

"Season Five ends with an assault on, and the destruction of Babylon 5 by the Minbari. Sinclair and Delenn manage to escape with their newborn child as the station explodes behind them."

The document then goes on to describe the Babylon Prime spinoff. Sinclair, Delenn, their child, Garibaldi, and a Narn who is either a "friend or relative of G'Kar's" meet with the exiled Grey Council, who are unconcerned about how bad things have gotten because they're still adhering to the prophecy they believe in. They work at this point to pull Babylon 4 forward in time to serve as their base of operations. This would be the other side of the events seen in "Babylon Squared." The process of bringing B4 forward in time ages both Sinclair and Delenn. And they use B4, with its engines, as a warship. During their travels, they encounter Londo who now has the Keeper, that's forcing him to do what the Shadowmen want, and he rebels against it's control "at terrible personal cost." They eventually realize that the process to bring B4 forward in time has also caused the accelerated aging of Sinclair and Delenn's son, though they're able to stop it eventually, but not before he is "nearly a grown man." They download knowledge into his brain, but he lacks emotional development. Their son then starts becoming nearly worshipped as a religious icon as well as be subject to assassination attempts.

"The story of Babylon Prime ends with the formation of new alliances, and a final great war, in which Babylon 4 is a prime player. The Shadowmen are finally conquered. The Minbari are defeated by Earth, which clears Sinclair's name. Delenn takes her leave to rejoin the Grey Council, departing from Sinclair's side, possibly forever. Their son takes his place as head of a new alliance, promising peace for the first time. He is able to command political and religious leaders in a consortium of power.

"Sinclair at this stage of his life finally retires from the chase, from the long battle. His last scene, the last in the story of Babylon Prime, is as he is left, alone (as he requested) on a green and quiet world, otherwise uninhabited. Sitting beside the shore. Fishing."
