Aeon Flux - Isthmus Crypticus
I’ve recently been re-watching Aeon Flux with a friend who’s never seen it before. I could probably write a lot more about the whole show but this episode in particular caught my attention for the quality of sound design and the range of effects created by sound (not sound effects) in the story.
"Trevor Goodchild’s latest obsession is an exquisite being which he keeps locked away in a secret chamber. It’s non-of Aeon’s business but…. "
We see the female Seraph-Trev for the first time in Ilbren’s projection, then a photo from the carrier pigeon, both without sound. We first see the male Seraph-Trev at 09:00 when Trevor uses a video screen to check on it; we can hear it wail in discomfort, which infuriates Trevor.
At 09:12 we see the female first-hand, and hear it cry out. On the other side of the wall that separates the two Seraphs, the male hears these screams and becomes distressed. As the male struggles and cries back, loud distorted drones begin playing from speakers in its pen, muting the Seraphs ability to communicate with one another.
At 10:05 Una, who has been enlisted by Aeon to work on an urgent translation, falls asleep while looking at a photo of the male. She dreams of it flying, through red and yellow clouded skies, before a bat-like Aeon swoops in and attacks. The music in this dream sequence is all reversed.
When Aeon finds Una has not completed the translation, she exclaims they will now have to improvise in the field. At 12:52 while Aeon drives them to Trevors complex, Una falls asleep in the passenger seat; out the window behind her we see a red and yellow clouded sky, just like the one in her dream. Each time Una’s head droops in micro-sleeps the energetic music (signifying the tense mood in the car) reverses; just like the music in her dream.
At 15:03 Aeon gives Una an earpiece and microphone so they can communicate while Una translates, and Aeon goes forward on foot: they navigate the maze-like complex together, using sound.
At 17:37 Una uses her mic and earpiece amp to create feedback, deafening Aeon, causing her to fall into the male Seraph’s chamber.
Aeon Flux stories often contain a lot of self-reference, and make use of motifs, which repeat on various scales. There are set-ups, and then payoffs: An idea will be suggested to the audience, often quite abstractly. This could be a piece of dialogue, in the form of a phrase, key word, or story element; a piece of animation, an object, a shape, an angle, or a motion (both character and camera); or in the case of Isthmus Crypticus a sound event, maybe music, or simply the way sound is used in the world of the series.
We see the idea of communication having both positive and negative aspects set up when the seraphs try to communicate with one another but are drowned out by speakers, then complimented later when Una deafens Aeon using their radios. The link isn’t literal, but still an interesting function for sound in the story, as now a device used for communication is being used as a weapon.
The call of the reversed music in Una’s dream also has its answer when she falls asleep in the car with Aeon. Opening us to ideas about mirrored or opposite worlds; things which are familiar, and yet strange. This theme of two halves being separated can also be seen in the large circular chamber that houses the Seraphs, with a single straight wall that connects the two. The dream Una has in the car features a composite Aeon-Narik that flits back and forward between the two, both in appearance and dialogue. Showing how fragile a separation there often is between what is real and unreal, known and unknown ect. Even the episodes title:
isthmus - ˈɪsθməs,ˈɪstməs,ˈɪsməs/
noun: isthmus; plural noun: isthmuses; plural noun: isthmi
1. A narrow strip of land with sea on either side, forming a link between two larger areas of land.
2. Anatomy: a narrow organ, passage, or piece of tissue connecting two larger parts.
Chung is consistently hesitant about providing clear answers to questions about the shows plot and themes; encouraging fans to draw their own conclusions:
"The Seraph-Trevs are not aliens, they are either mystical or genetically engineered by Trevor (take your pick)."
– Peter Chung (from a Q&A with fans)
This embraced plurality creates far more powerful work, by actually creating ‘work’ or problems to be solved, and not answers in the forms of stories. And the use of this setup-payoff method is a great way to get an audience to come along for the ride. If you simply tell someone something you want them to know, they can be resistant to it, for all manner of complex reasons involving layered personal defences. But if you can present them with a question – maybe in the form of a puzzle, half an answer, only a fleeting glimpse of something tantalising – then later return to this idea, you bypass the personal defences of the viewer. You create a bridge between the audiences inner world (via their memory) and the outer world you want them to connect to. Sound, for many complex reasons I can’t get into now, is often the best way through this defensive wall (isthmus).
“On a side note, writing Seraph-trev in the plural reminds me of something in Hebrew grammar called a smikhut, which the construction "Seraph-trev" seems to fit. If you go by the rules of the Hebrew language (which the word seraph is derived from), then the plural would be Seraphei-trev (this sounds more correct to me, as "Seraph-trev" sounds more like Hebrew to me than English). Anyway, I guess that's not really relevant, but it's something that occurred to me and I thought I'd mention it.
And now that I think about it more, perhaps there is relevance to this. If you treat "Seraph-trev" as a smikhut, it means "the seraph of trev", or "Trevor's Seraph" if you want to extend it a little. Makes me wonder if Todd French (who wrote the episode) knew any Hebrew... “
