Solution

Henry then asked, "So, from those fragments you can remember, are the personalities or ways of speaking of your companions the same as your actual memories?"

Thena thought for a moment, then shook her head and said, "No. They're like a completely different person."

"So just treat those as if they weren't your memories. Maybe it's just a compensation mechanism for memories, making you project other people's memories onto your own." Henry gave a plausible explanation.

"Do you have a solution, Henry?" Kingo asked.

"I do have an idea."

"Then hurry up and tell me," Gilgamesh.

Even Thena, who thought she would live like this for the rest of her life, was curious about Henry's thoughts. Her empty eyes regained a little vitality.

After thinking for a moment, Henry still brought up the sketchbook. This time, however, he used two different colored pens to write in the same area, with the two colors mostly overlapping.

Have you ever played this game? When two colors of text are written together, and you only want to see one color of text, what should you do?

Seeing the confused expressions on the three Eternals' faces, Henry had no choice but to say, "Alright, no need to guess. Just cover it with cellophane of a different color, and all that will be left is the color you want to see."

"I don't have cellophane of the same color or thin enough fabric on hand right now, so I can't demonstrate it for you. But you can understand my situation, right?"

This time they finally got a positive response. However, they didn't understand how to use this method.

Henry continued, "Simply put, it's about creating a filter to externally cancel out excess brainwaves and suppress brain responses related to memory."

"I don't even need to worry about what What If...? the wrong brainwaves are filtered. Because Thena's normal memories and those that interfere with her are like narrations using different frequencies of brainwaves."

"Suppressing these unwanted memories will prevent them from interfering with your daily life. This should improve what you call ' Mahd Wy'ry' and reduce the burden on your brain."

Kingo questioned, "Wait a minute, you said it's just suppression, not erasure. Doesn't that mean those memories are still there?"

Faced with Kingo's doubts, Henry patiently explained, "No matter what kind of creature it is, the brain does not process memories like a stone tablet or paper, where things are recorded and occupy a place forever."

"Memory is categorized into short-term memory and long-term memory. Once it enters the long-term memory stage, as long as the event is not recalled for a considerable period of time..."

Memories of this event will be stored in deep memory and then forgotten.

"So the brain clears out unimportant information on its own. I believe that even the Eternals wouldn't be able to remember what they ate for breakfast or dinner on a particular day five thousand years ago, right?"

Gilgamesh said with a strange expression, "Hmm, actually I remember. Which day do you want to ask about?"

Kingo and Thena, both members of the Eternals, looked at their companion with disdain, their heads tilted back.

Kingo was even more blunt, saying, "Ignore him. Do you think he's so fat just because he has a large frame? You're right, we really don't remember things from five thousand years ago."

Henry, who almost couldn't continue after being rebuked by Gilgamesh, composed himself and continued calmly, "In short, Thena's problem is that she uncontrollably and frequently thinks about unimportant things, which increases the burden on her brain."

"If we could suppress this uncontrolled state of the brain, I believe the situation would improve. The filter I've come up with is specifically designed for the brainwave frequencies of those fleeting fragments." That is, when it absorbs the emitted signal, it responds with an opposite waveform, thus canceling it out. You can imagine it as a sound-absorbing device; all sound waves are suppressed upon contact, thus eliminating the sound.

"It is precisely because you are Eternals that your brains are so precise that you can use this method to accurately suppress those interfering memory fragments."

"What If...? it were an ordinary human, their brainwaves would be too chaotic. Only special individuals like Professor X, who possess Mind Stone abilities, could do something similar. The reason I say it's possible is based on research conducted on this type of ability."

Henry's explanation left the three Eternals looking at each other, unsure if they had understood.

However, Henry added, "But I must make it clear that this approach is not a cure for Thena, but merely a corrective measure."

"Just like how people wear glasses to improve their vision when they are nearsighted. Um, do you know what glasses are?"

Gilgamesh shook his head in dissatisfaction and said, "We still know what glasses are."

"Oh, that's good." Henry looked at Kingo and said, "Anyway, that's the method I can think of. It's not a treatment, just a correction."

"What If...? the orthodontic device I make, the one that functions like 'glasses,' is destroyed, Thena will return to normal."

"Of course, we can just make a new one now, it's no big deal. Can this be considered fulfilling my promise?"

Kingo nodded and said, "I just want to find a 'solution,' not necessarily a cure, so I can accept this outcome. But are you sure it will work?"

"Don't worry. I'll make it first and make sure it works before I take payment. That way, I won't run off with the money," Henry said with a smile.

"Reward? What reward?" Gilgamesh asked, puzzled.

Kingo didn't hide anything and said frankly, "I promised Henry that if he could solve Thena's problem, I would give him a vial of my blood."

"His initial idea was to study our suits and then make one for himself. But as you know, we can only wear the suits on the Domo."

"But I think that What If...? Henry can solve the problem, drawing a vial of blood for him wouldn't be unacceptable. Of course, that's assuming it's all feasible."

"One tube? Is that a lot?" Gilgamesh asked hesitantly.

Kingo replied, "No, of course not much. Only about a hundred milliliters, roughly the volume of a finger. Oh, my finger, not yours."

Gilgamesh immediately exclaimed excitedly, "It's just a little bit, I'll have my blood drawn too. As long as you solve Thena's problem."

Thena, who was involved in the incident, didn't refuse and said, "I can do it too."

Henry said in surprise, "Well, originally this was just an agreement between me and Kingo. But What If...? you're willing, it's triple the reward for me, so there's no Reason not to do my best to complete it. Is that alright?"

"Of course," Gilgamesh stated.
