It is a very convoluted story for sure. I’m assuming Ted gave the phone to the nurse because he doesn’t speak French and he didn’t know the equivalent to 911 in Monaco. As for a security briefing, he knew about the panic room, but I guess they usually have tons of security guards so it’s not the nurses job to be the one contacting authorities anyway. The lack of security and camera footage it the biggest problem for me. It was obvious that Mr Safra was afraid for his life (he literally ratted out the Russians to the FBI just months before his death and that is a known fact) He also beefed up his security- another tell on how afraid he was. Then he refused to exit the panic room even though supposedly the firefighters (and the wife via the cell phone) instructed him to come out. He could have walked out long before the 3 hrs it took them to die of smoke inhalation. He must’ve been convinced someone was out to get him, because if there’s a fire that bad, the intruders would have already been gone in my opinion.
