Now, please notify the captain that I'm here, I need to meet with him and the rest of the command staff ASAP. I assume my usual quarters in the brig are available. I have grown so attached to the place.
This episode contains examples of:
Earth-Shattering Kaboom: The allies of the Shadows evacuate Z'ha'dum, then seemingly set a self destruct that goes off soon after the White Star arrives.
Foreshadowing: While Bester is speaking to Caroline, he mentions that he has things in store for Sheridan's crew, ones that will hurt them a lot more than he's been hurt.
Frameup: President Clark's intention is to destroy an Earthforce patrol and leave evidence that Babylon 5 was responsible. Thanks to Bester's warning, it backfires.
Hyperspeed Ambush: Black Omega intend to take the patrolling Earthforce picket by surprise and destroy them, leaving Babylon 5 to take the blame, but Ivanova's squadron gets there first and lets them destroy the Black Omega fighters.
Naval Blockade: President Clark has Earth Force cut off all traffic between the Earth Alliance and Babylon 5.
Reality Subtext: Garibaldi says that many people warned him against hiring Zack, but it worked out well, a reference to many of Jeff Conaway's former co-workers warning JMS about the problems his heroin addiction had caused, yet he'd kicked it by that time and always worked at his best on the show.
Royal Inbreeding: Minister Virini suggests this for a reason why the Royal bloodlines have left something to be desired lately.
Stealth Pun: When Zack is giving the briefing to his subordinate regarding customs, Londo and Bester come through the gate within a minute of each other. Zack then decides to get out of there, since for all he knows the next arrival could be the Second Coming. After he leaves, the subordinate checks through three Elvis Impersonators. The three Kings.
Touched by Vorlons: While it's clear that Lyta was modified when she went to Vorlon space by now, we start to get hints of just how powerful she actually is.
What the Hell, Hero?: Sheridan realizes the timing of the above mentioned kaboom is no coincidence and the only one who could have tipped them off was the most powerful telepath on board while they were in hyperspace. When he confronts Lyta about it, she doesn't bother to deny it, and he angrily responds that if she ever does anything like that again he will let Psi Corps do whatever they want to her.
Although the way he says it it seems that his only real problem was that she did it behind his back.
There's a contrast, later, though-after they use thirty of the Shadow-modified telepaths against the Earth Force destroyers Bester confronts Sheridan, demanding to know if Carolyn was one of them. She wasn't. Sheridan tells him that having suffered losing someone, regaining them, and losing them again, he wouldn't wish the experience on anyone, even Bester. Sheridan has no problem using people when it's necessary for the greater good, but he doesn't inflict pain for the sake of it, setting him apart from Lyta, who justifies herself here by saying Bester has caused so many people to be separated from loved ones, he deserves to experience it himself.
