Due to my rambling science post will try and keep these short. WHat a cracking set of episodes though.
Point of No return
Really good episode, you can feel things are beginning to get out of control and events begin to force the hand of the conspiracy of light. The exchange between Sherridan and Garibaldi has Sherridan for teh first time with no idea what his next move will be. If he had a plan he may have been able to stop Michael going to bust up the night watch recruitment, but without a solution he can't stop him. Even at the end they know the solution is only stalling for time. I do think general "Wink wink nudge nudge" must have been arrested shortly after, prize for most obvious hints in a message. I remember on first viewing I genuinely didn't know which way Zack was going to jump, B5 never shied away from letting its characters make bad choices and then deal with the consequences. The Londo Plot is not bad either, and the final exchange between Londo and Vir is a nice juxtaposition with the exchange at the end of Dust to Dust.
Regarding Charly's take on the Chain of command. You are correct that station security appears to be closer to a civilian force like the Police than Military. The mistake Clarke actually made was in how B5 is run. The colonies who he ordered into martial law would have been administered by civilians, however B5 is administered by the military. Chain of command meas that B5's orders have to come from a different source, regardless of makeup security are under overall command of the station commander, who can not be given orders by a civilian agency.
Severed Dreams
Firstly. I love angry Delenn.
I also love the Omega Class Destroyer. It's not pretty, not even handsome, but I love it's functional, utilitarian look. In fact I love the general Aesthetic of the Earth Alliance ships. I love the way each ship has its own logo (You can see part of the churchill's in the background) remeniscant of current Naval destroyers. Another nice detail, not actually explained but observed, is the use of "interceptors" basically guns to shoot down incoming fire. Again this is similar to some of the anti-missile systems on present day Navy ships. The idea of using the fighters for the screen, as we see in the early fight between the Alexander and the Clarkestown, was later purloined by Battlestar Galactica, in the pilot fighters are used to shoot down incoming cylon nukes.
Anyway, enough going gooey over space ships, reat episode. They build on the reluctance of the crew to take the actions they ultimately take, considering it is a Military coup we are looking at here it had to be handled just right so as not to make the good guys look like they're knocking over a legitimate civilian government. It has been done that well. There is also a lovely moment where B5 avoids the cliche, Sherridan asks any C&C crew who don't want to be involved to leave, and people actually leave, so rarely happens.
Effects work is superb, the battle seems both epic and brutal. A small nitpick (Which seems awfully like complaining your delcious sundae is 1 chocolate sprinkle short) Near the end Sherridan signals the Roanoke, but it was destroyed when the Churchill rammed it. The Agrippa was the surviving ship. Sorry.
Finally, Delenn's big entrance. Did I say I love Angry Delenn? I do. Probably my favorite speech from Babylon 5, Delenn's response to "Don't make us engage" is just "Why not" in two words she says "We can take you without breaking a sweat" then the speech followed by "Be somewhere else" today's lesson kids. Never, ever, EVER mess with Angry Delenn.
I love Angry Delenn.
G'Kar is also fantastic in these episodes but I have rambled on enough. Sorry, intended to keep this short.
Sneaky edit - Plausable explanation as to why they were reluctant to use Draal, Clarke has shown an interest in aquiring advanced tech (Shadow ships for starters) now as far as we know all he knows about the great machine is that it currently has an eccentric Nimbari in it who has told everyone to bugger off. Finding out that it is fully operational and at B5's disposal may attract a lot more unwanted attention further down the line. Obvoiusly in a crunch they would have called him but I coudl see why they wouldn't just let Draal take care of things from the off.
Great work guys.
