How to treat the biggest Bug in the good-looking Spanish movie Invisible Guest?

I think the biggest bug in Invisible Guests is jet lag.

How can parents who have lost their son determine when the man will see a lawyer?

First, the real female lawyer and the male host agreed to meet through the male lawyer, and the male lawyer met the real female lawyer in the real female lawyer's office. My father learned about the meeting between the two during the tracking process, but how to determine the real meeting time agreed by the female lawyer and the male host? (According to the bug set by the mother for the man, the victim's parents don't have the conditions of a high-level bug, so they have to turn off their mobile phones before they can pass, otherwise the signal of the bug will affect the signal of the mobile phone, so eavesdropping will know that they have passed.)

Second, after the real female lawyer and the male host agreed on the time, how did the victim's parents grasp the time difference? That is, the fake female lawyer played by the victim's mother must meet, talk and leave the male lawyer before the male lawyer meets the real female lawyer. Then she must get to the designated place before the real lawyer. To achieve this goal, either arrive earlier than the agreed time, or create trouble for Zhen and female lawyers to delay the time. The victim's parents are only two, and there is no third party to help them in the whole film, and they don't trust the police. In addition, if you really meet a female lawyer, you will be late, and there is a great chance that you will contact a male lawyer to report the situation. So the plan was passed. Then we have to get there early and talk about it. The movie lasted more than two hours, and we put aside all kinds of memories. According to conventional speculation, the fake female lawyer arrives at the host's residence at least one and a half hours in advance. As we know, a real lawyer is a very powerful lawyer who is ready to retire and has never lost a lawsuit. Faced with such a female lawyer, why does the man have no doubt about her early arrival?

Third, shortly after the female lawyer arrived, the man talked to the male lawyer. The male lawyer asked the male owner if he had seen a female lawyer, and the male owner answered yes. Then it means that the arrival of the fake female lawyer coincides with the appointed time. That would be weird. Real female lawyers are late? Still so late? She's late. Why didn't she contact the male lawyer? Suppose she can't contact the male lawyer, but she doesn't contact the male host to tell her that she is late.

Fourth, fake female lawyers talk on the phone with male lawyers. Male lawyers have had direct contact with real female lawyers. But the male lawyer didn't hear it, and he wasn't talking to a real female lawyer. (This bug can be explained if it is difficult to explain. It can be considered that male lawyers have limited contact with female lawyers, or that fake female lawyers imitate the voice of real female lawyers when answering the phone. )

I think the biggest bug is jet lag.
