Think I thought it may be keeping the machine hidden, but as Matt pointed out, Sherridan uses its holo-projectin system to address the whole station, earth force loyalists and all. Also the Captain of the Hyperion from voice in the wilderness definitely saw it unleash hot laser death on the alien ships. I woudl imagine he reported the presence of an alien weapons system on epsilon 3, along with Draals warning for everyone to stay away "or else" It is basically a plot hole and would have probably been worth introducing a reason it couldn't intervene, For example, when they get the Holo system Ivanova could tell Sherridan "bad news, The great machine's weapons are offline, Draal won't say why." He coudl be busy dusting, Playing Skyrim perhaps he already knew Delen was coming to the rescue.
Warning: Spoiler!The reason could be revealed to be the amount of power used to make War Without end Happen.
In fairness, there aren't too many situations where the Great Machine is needed, but it being there is a pain for this particular episode.
Anyway, on to the episdoes
A Late Delivery from Avalon.
It has some redeeming features, we have Marcus and Franklyn banter and bonding, some top Marcus action in general. I do particularly like him assigning Knights to Everyone at the end, and I liked him pleading with Stephen to let Arthur continue believing he is an ancient knight, although it woudl have been a nicer twist if he'd just been a tax man and Marcus just though having King Arthur around was much cooler. Drunk G'Kar is also entertaining.
The Bad, the epsidoe seemed a bit of a jumble to me. The B-Plot with Sherridan and Ivanova feels like it should be the A-Plot and have more in it. Meanwhile the Arthur plot has the interesting ideas, effectively the guy who pulled the trigger on the guns that started the war suffering some serious Guilt and PTSD, but it jarrs with the general light tone of the rest of the plot. It also doesn't help that Michael York sounds like Arthur from "Holy Grail" when he says "I am Arthur, King of the Britons" Overall Agree with Sherridan, All very interesting but don't we have more important things to do.
Also, what is it with garibaldi getting dumped with the comedy plotlines, first Garibaldi vs. the Comedy computer AI, next Garibaldi vs. Comedy beurocratic postman.
Ship of Tears
Bester's here, always a good sign, and his character is further fleshed out. The character we see who is closest to an out and out baddy has a human side. Great to see Garibaldi not lumbered with a comic sub-plot. Instead his studies of the book of G'quan prove very worthwhile. Actually, its surprising how much happens in this episode, we also find out why Sherriden was reluctant to tell G'Kar about the shadows. Finally, we see a bit more of the Newer Starfuries (Thunderbolt for completists) a nice enough ship but rather too X-Wing (just about has S-Foils) Much prefer the classic Starfury.
Warning: Spoiler!Well, a number of things set up in this episode, obviously the Cyber telepaths are weaponised at the end of the next season, they do use telepaths to "Jam" shadow ships, and indeed find out this is why telepaths were created. The cyber-Implants are also important at the end of this season. Finally, the scary Alien surgeons. I'm sure we see them in Season 5 doing unspeakable things to Londo, so might this be a first appearance of either the Drakh or a species who work for the shadows (And later the Drakh) I completely forgot we see them in this episode.
Anyway, much more fun to come. I look forward to the next cast
