The gravity cabin that contained Anna's body was transported to the basement of the Genetics College laboratory. Peter specifically put the gravity cabin with John. Thus, if Anna woke up, she could see John immediately.
As the metal door was opened, the gravity cabin slowly entered the basement. Meanwhile, Anna's father was on the innermost platform. He did not have a body now, only a mechanical head.
In order to prevent Anna from breaking down when she saw John, Peter specifically let Betty in and combined John's mecha body with his head.
John hated his mecha body. However, when he learned that his daughter, Anna, was still alive, he was very cooperative with Betty as she combined his head with his body.
