I am re-watching the entire Babylon 5 television series. I had not seen a single episode since B5 completed its tumultuous run. Does J. Michael Straczynski still have the touch? Come along and find out.
In Valen's Name: Talia Winters' telepath mentor, Jason Ironheart, shows up on Babylon 5, running from the Psi Corps. He had volunteered for Psi Corps research into creating stronger telepaths. It turned out that the experimental treatment was intended to create stable telekinetics, and succeeded in spectacular fashion. Not only could Ironheart manipulate matter and energy with his mind, he could see into the mind of any telepath, no matter how powerful. That's when he discovered his telekinesis was intended to be weaponized, used for covert assassinations and the like, so he killed the program head and fled. Hot on his heels is Alfred Bester, a tough, ruthless Psi Cop intent on taking him down. As Bester rampages through the station (relatively speaking) breaking telepath rules right and left, Talia brings Ironheart to Sinclair. Ironheart explains his discoveries to Sinclair and warns that the Psi Corps is growing too powerful to trust. Ironheart himself is growing more and more powerful, losing control of his abilities as they outstrip his mastery of them. He is becoming a danger to the station. Bester and his team catch up with Ironheart, there's a fight (Bester loses) and Ironheart transforms into a being of pure consciousness or somesuch, infinitely more powerful than before. Then he waves "Bye" and goes off to wherever supremely powerful entities go. Bester intends to bring Sinclair up on charges for harboring a fugitive, but Sinclair threatens to do the same with Bester for all the Psi Corps and telepath laws he violated, so their pissing match ends in a draw.
Meanwhile, Sinclair's lady friend Catherine is about to launch a lucrative scouting mission to the abandoned world of Sigma 957 to search for Quantium 40 deposits, a very valuable material used in the manufacture of jump gates. G'Kar warns her not to go, indicating strange things happen around that system. Catherine ignores him, and once there encounters a massive, mysterious ship that vanishes leaving her without power in a decaying orbit. This is the first appearance of one of the elder races of the B5 universe, outside of the Vorlons, of course. At the last moment, Narn fighters sent by G'Kar arrive and rescue Catherine. It's one of the first time G'Kar is shown making a gesture that isn't wholly self-centered.
What Jayme Says: I remember first seeing this episode, and being surprised to see Walter Koening guest-starring. I also geeked a little when they revealed his name as "Bester," which of course is a reference to Alfred Bester, author of The Demolished Man which has some influence on this episode. I was a little disappointed when they revealed the character's full name as "Alfred Bester," which pushed the homage into elbow-in-the-ribs territory. This episode is our first real introduction to the active menace of the Psi Corps, Ivanova's hatred of them because of her mother being a bit too removed to drive the point home that the Corps is a menace to everyone, not just unwilling telepaths. Bester is bad news, all the way down to his black, fascist uniform. That said, the teeth are pulled from this episode pretty quickly. Despite warnings of dire consequences to come if she helps Ironheart, Talia helps him repeatedly with no real consequences. Yes, she's mind probed, a painful process clearly analogous to rape, but that comes early in the episode to show how ruthless Bester is, and Talia passes anyway. There are no consequences for Sinclair, who openly defied and obstructed Psi Corps business, and there are no consequences for Bester, who disregarded and broke countless regulations and laws in his pursuit of Ironheart. Realistically speaking, this sorry incident should've ruined all three parties rather than preserve the status quo because of the blackmail fodder each party has on the other. It also has one of the most Star Trek endings in all of Babylon 5, in which a character inflicted with god-like powers evolves into a higher form of being and is never seen again, thus resolving the moral choice the regular characters would otherwise have to make. And while I like Andrea Thompson/Talia far more than Lyta Alexander/Patricia Tallman, her acting is undeniably stiff and stilted here. False notes like this, coupled with the abysmal performances in "The Gathering, gave rise to that long-running and (in my opinion) misguided claim that Babylon 5 is rife with bad acting.
Ultimately, "Mind War" isn't among the series' best episodes, but is notable for what it sets up for the future.
