History Recap / BabylonFiveS03E13ALateDeliveryFromAvalon

* UnstoppableMailman: He's had to resort to smuggler networks and prices have risen accordingly, but the mail sill gets through.

* HollywoodPsych: It is generally considered to be a very bad idea to attempt to cure delusions by abruptly confronting them. Any doctor that passed their psych rotation shpuld know that ''Franklin.''

* BashBrothers: G'Kar is so impressed with Arthur's gallantry against a pack of lurkers, he immediately down from a balcony to join the fight. The pair get drunk afterward, and Arthur promptly "knights" G'Kar with his sword.

** Ends up foreshadowing the Reveal of Babylon 5

* ArbitrarySkepticism: Marcus points out that completely dismissing Arthur being the real thing when the Vorlons [[Recap/BabylonFiveS02E21ComesTheInquisitor have abducted at least one noteworthy figure from Earth's history for their use.]] He's wrong in this case but it's a fair point.

* MeaningfulName: [=McIntyre's=] old ship, the ''Prometheus'', is named after a Titan in Greek mythologoy who gave fire to mankind.

Garibaldi, on the other hand, is suffering from a lack of sufficient awe--for the Post Office. His jittery aide wonders what they're doing breaking into the mail locker. Garibaldi says to put a lid on it; They've faced down the entire Earth alliance and two carrier groups, what is this guy whining about? Sure, sputters the lackey, but this is THE POST OFFICE. Garibaldi scoffs and breaks the lock, only to find the clairvoyant postal worker ready and waiting for him. He announces that the Postmaster General will hear about this. As a final insult, he charges Garibaldi an excuse 20 credits for the lock.

Back in [=DownBelow=], Arthur finds a distraught old woman weeping after a framed picture of her late husband was seized by ruffians. Arthur vows to help her, and sets off at once to vanquish the thieves. On the upper level, G'Kar is busy with a smuggler who is passing messages between the Narns and their families back on the homeworld. They hear a scuffle and from a balcony they see four thugs assaulting a man. Neither of them intervenes until Arthur appears, sword in hand, and demands the return of the portrait. He gives the loan shark a sound thrashing, with an admiring G'Kar looking on, but more thugs appear from behind. That prompts G'Kar to intervene on Arthur's behalf, leaping down from a balcony and busts loose into his Wolverine stance.

Meanwhile, the ''Asimov'' passenger from before has reemerged wearing a cape and chainmail. Great. Just when things were starting to get normal around here. When the man passes through customs, an alarm immediately sounds. One of the guard politely informs him that he's carrying a weapon, which is a violation under station rules. This causes him to go absolutely berserk, whipping out a broadsword and proclaiming himself King Arthur, son of Uther Pendragon and King of the Britons. Well, ''that'' was unexpected. Thinking quickly, Marcus calls off the guards and bows reverently to "Arthur", who is pleased to be addressed by another Briton. Marcus promises to send word to Galahad and Lancelot - which suddenly provokes Arthur into holding his sword to poor Marcus' throat. Have at you, sir! As usual, Marcus' literary expertise is impeccable... but his chronology was off. ''This'' Arthur hails from the Battle of Camlann, where nearly everyone - himself included, supposedly - was slain by Mordred's troops (Spoiler Alert). Recovering from this blunder, Marcus manages to sweet-talk Arthur into following him to [=MedLab=]. Lead on!

The Jumpgate opens and an Earth passenger ship, the ''Asimov'', zooms towards Babylon 5. Up in C&C, Sheridan and Ivanova are grousing over the steep drop in trade since they declared independence from Earth. Docking fees make up the biggest chuck of their income, and they can't rely on the Minbari ships to protect them forever.

* EternalEnglish: Lampshaded by Franklin, as he says that Arthur's "speech patterns are too contemporary" and his "vocabulary is all wrong".

* ARiddleForTheAges: As the image caption notes replica swords are not that hard to come by but it is unclear where [=McIntyre=] found battle ready chainmail.

* HollywoodPsych: It is generally considered to be a very bad idea to attempt to cure delusions by abruptly confronting them. Any doctor that passed their psych rotation shpuld know that ''Franklyn.''
