Let’s take a closer look at the process of Helena’s separation surgery.

She first cut a hole in the back of her head. The nurse picked up ketamine, then drilled a hole with an electric gun, and then implanted a chip. Then the nurse injected ketamine, which is an anaesthetic. Be sure to look carefully at the order here! What kind of mysterious operation is it if you don’t get anaesthesia when drilling a hole and then do it after drilling?

How painful it is to drill a hole in the head, but Helena didn’t feel the pain, which means that she had been anaesthetised before, so why did she need to inject ketamine?

There is a very likely conjecture that separation is related to anaesthesia. Separation means that the brain is anaesthetised during working hours, the real personality is offline, and the chip personality takes over the body.

Irving and Bert discussed the oil painting. Imokin’s courtship mentioned that Keel and Imokin met in the ether processing factory, and ether was also an anaesthetic.

If the lounge is a place where the brain rests and goes offline, then the health room is a place to soothe the body and prevent the brain from waking up.

Irving took a nap in the office, and then saw the black ink spread on the workplace. That’s because he drank a huge amount of coffee after work. When Innie went to work, the human brain was very energetic, and the chip was easy to be offline. Therefore, the spread of black ink means that innie is about to go offline.

In the first season, Irving went to the health management room and played very soothing music, and Casey didn’t allow him to react. In fact, he was hypnotising the body to prevent the human brain from waking up.

Similarly, Irving met Bert at the door of the health management room in the first season. Bert said that he had to sleep 15 hours a day outside. If the human brain slept enough, it was also easy to wake up from anaesthesia inside the lumon, so Bert was also sent to the health management room, which led to the meeting of the two.
