According to Lin Fan's speculation, the behind-the-scenes manipulator obtained the only source of information that the target individual would board this flight to the United Kingdom, and they had already purchased a ticket. Upon checking the ticket information, a total of 69 people had booked this flight.
In other words, the target individual is among these 69 people.
However, to ensure the target individual can successfully board, the manipulator does not dare to conduct an in-depth investigation on these 69 people, nor do they dare to contact them, fearing that once they alert the target, the individual might cancel the flight.
If that happens, they would then be unable to get any more information and certainly couldn't locate the target individual, let alone eliminate them.
For the sake of caution, they decided to remain inactive, not to investigate, and let the target individual board the flight smoothly.
