After opening the "door" to the Body of Heart and Mind, Klein carefully extracted the memories related to The Fool. He gathered them together and "Grafted" them above the gray fog.
Following that, he saw the blonde-haired Audrey, who had a light white silk scarf covering her eyes, appear on the ancient stone steps. Step by step, she landed onto his mind island via the sea of collective subconscious.
After some hesitation, Klein no longer allowed his consciousness to stay high in the sky. He gave up the corresponding control and allowed them to return and fuse together.
If he didn't do that, he would maintain absolute rationality in the subsequent treatment, making him unable to be moved by all kinds of memories and lose the possibility of strengthening his humanity.
This meant that Audrey's treatment was destined to fail right from the start.
