#but that room seems way too echo-y for the vds to take place in

[good-beanswrites]

My thoughts on how the Milgram mv machine works based on the evidence we have:

(I know there’s been discussion about where exactly the interrogations take place, but wherever they are,) the prisoners are made to sit in a specific chair near the wall that houses the machine.

It’s ordinarily hidden, but the wall panels shift aside to reveal it when the mechanical sounds play in the dramas. As well as the walls moving, the chair transforms to restrain the prisoner and attach whatever it takes to access their brain. The fact that none of the more frightened prisoners try to run or break it makes it seem like they physically cannot. This is why Fuuta sounds so panicked, and why Amane is suddenly helpless in front of Es in their T1 vds.

(My mind conjures very classic sci-fi mad scientist machines with wires, pipes, lights, nodes, needles, etc, but I’d love to hear how other people visualize it.)

In some vds (maybe all? I’d need to check,) you can hear Es take some steps right before their iconic line -- it would make sense that for safety reasons, the power mechanism is placed across the room. Once again it could be anything, but the sound effect makes me think of one of those giant wall-mounted levers you have to pull down.

The voice dramas don’t really provide the type of crime details that an actual interrogation would reveal, and it’s odd that they’re placed before the extraction rather than after Es gets to see the new details. This leads me to believe the machine functions with priming. All Es needs to do is get them talking about their murder, so it’s on their mind.

The video produced is much like a (non-lucid) dream. Even if the prisoners figure out that this is how it works, they can’t control it just by thinking really hard about something else. The murders produce the strongest emotional affect, and that’s what it picks up on. If someone else used the machine, it would default to whatever gave them the strongest emotional reaction in the ~15 minutes beforehand, hence why Es’ video focuses on their daunting task ahead. (The Undercover theory is still a bit loose, though, given the private shots that Es wouldn't have known about). It’s why the videos are usually closely linked to the vd topics/beats. I also like to think that the reason their prisoner colors appear so much is because they’re looking at those colors on their uniform 24/7.

The bell rings to inform Es that it’s the optimal time to use the machine -- the prisoner has been thinking about things for long enough that the video will be about their crime, and if the conversation lasts much longer they’ll start thinking of other things. It’s at a different time for each prisoner because it’s based on the specific conversation. I guess Jackalope is listening in to the interrogation, timing it perfectly. (The only one that kind of messes with this theory is Yonah, because they just keep talking afterwards lol, but it could just show that the interrogation is still in Es’ control.)

Their “Sing your sins” is the final priming nudge to get them to think of their actions as a sin, revealing their guilt.

Once activated, the prisoner enters a sort of trance/sleeping state. It’s very much like REM sleep, with the machine forcibly activating neurons and recording the output. The prisoners have asked Es what they saw, meaning they don’t remember the mvs. I like to think the prisoners do experience the mv in real time, acting as the major version of themself that appears, but can’t remember it afterwards. It’s when you experience a dream, but as soon as you wake up you’re just left with fleeting emotions and memories right on the tip of your tongue.

The video plays immediately upon extraction -- whether on a huge projection or little screen depends on which room it’s in. It simultaneously saves the memory so that Es can rewatch it later (on those old TVs in the jailbreak mix). The machine downloads the song and video together, but requires special parts to retrieve them. The technology is pretty new and fragile, so if one is broken, there might be a delay between when Es can hear the extracted song and see it with the video. (That’s my justification for Kotoko’s delays -- after 9 prisoners the parts wear out, or maybe Mikoto himself overheats it with his complex situation.)

Based on the lack of conversation we get afterwards, I picture Es leaving before the prisoner wakes from the trance. The machine adjusts their brain back to normal before they awaken, restraints freed and able to return to the rest of the prison.

It’s very much like a dream, so it’s not harmful despite the amnesia/head injuries the prisoners have. It does, however, exhaust them. Brain activity alone takes a lot of energy, so forced brain activity with added emotional strain would cause them to feel pretty drained the rest of the day.
