The personnel in charge of the lie detector, along with the invited psychologist, reviewed the data of the two individuals in detail.
The psychologist stated, "Their physical data did not change significantly."
"Not much has changed?" Watson found it hard to believe.
The mother and daughter seemed fine at first glance, but there were many things about them that made him suspicious.
This lie detector didn't detect anything wrong?
"Yes, when asked all the questions, their physical data didn't fluctuate much, and neither of them showed any suspicious behavior emotionally," the psychologist stated frankly.
"So, they're both fine?" Watson asked, hands on his hips, sounding annoyed.
After all these days of effort, is it all for nothing again?
"No, that just shows there's a problem," said the person in charge of the testing equipment.
Watson didn't understand these technological things very well and was a little confused by what he was being told.
"Didn't they say their physical data hadn't changed much?"
"It's suspicious precisely because there wasn't much change." The man said, pulling up Mr. Ling's lie detector data from before. "This is Mr. Ling's data. When asked about Gu Weiwei, his emotions changed, although not very strongly."
Watson looked at the two of them and asked.
"So you're saying... this Mr. Ling is suspicious?"
The psychologist shook his head and offered an explanation.
“Mr. Ling, this is a normal physical reaction. When a person related to their family who has died is mentioned, his various data change. This is a normal reaction.”
"However, Mrs. Ling and Miss Ling have not shown any significant changes in their physical condition or emotional state regarding Miss Gu."
"They appeared very calm and composed, even though their answers and data seemed flawless on the surface."
...
After hearing what she said, Watson understood to some extent.
"Compared to Mr. Ling, Miss Weiwei had the most contact with them, mother and daughter. Someone who was so close to them passed away, and her heart was transplanted into Ling Yan, but when she was mentioned, their reaction was as calm as if they were strangers. This is not normal."
“Yes, that’s exactly what I mean,” the psychologist said.
Watson gritted his teeth. "These two are definitely suspicious."
"Furthermore, when we asked if they wished Miss Vivi to die so that her heart could be transplanted, both of them firmly denied it," the psychologist said.
“Normal people, driven by the instinct for survival, would have such evil thoughts to some extent, but they are vehemently denying it, as if… they really don’t want us to see their true reactions and emotions on this issue,” said the person in charge of the lie detector.
Watson nodded thoughtfully. "Reactions that seem too ordinary are often the extraordinary ones."
Mr. Ling had less contact with Gu Weiwei than he did with his mother and daughter. When Gu Weiwei was mentioned, her physical condition and emotions changed.
However, the Ling mother and daughter gave a very simple answer, and their expressions were calm and unsmiling, which was very abnormal.
He claimed to be a close friend who would die for someone, but his eyes and expression showed no grief or sorrow for the other person's death.
They were deliberately restraining themselves, suppressing their true emotions.
If you're not guilty, why hide your true feelings?
"These conclusions, drawn from their reactions, suggest that they intentionally withheld their true emotions and cannot be considered direct evidence," the psychologist stated.
Watson smiled meaningfully, "Thank you for your hard work, this is enough."
At least, this confirms that his suspicions were correct.
