Plot hole: When John arrives at Diana's crash scene, he has no reason to believe that she was involved in the accident. He doesn't know what she was driving. He would have just assumed it was someone else and kept driving through. But instead, he gets out of his car and asks where the children are, just assuming it was Diana there, for no logical reason.

Continuity mistake: When John is driving to the gas station, the back door of his car is missing, although it was there when he was driving from his house.
Ted Myles: Stay with me. I know how this sounds, but I've mapped these numbers to the dates of every major global disaster from the last 50 years in perfect sequence. Earthquakes, fires, tsunamis... The next number on the chain predicts that tomorrow, somewhere on the planet,81 people are going to die, in some kind of tragedy.
Phil Bergman: Whoa. Just step back. Have another look at it! Systems that find meaning in numbers are a dime in dozen. Why? Because people see what they want to see.
Question: The whisper people bring the selected boy and girl to safety before the final day of earth. Why do they plant a message to be found and decoded just before the final day? I do not think the whisper people need any help from any humans to save humanity (and organize a whisperers' version of Noah's Ark).
Answer: There is no intention on the part of the whisper people to warn humanity as a whole, merely a select group of children who appear, due to their telepathic powers, to be the next stage in human evolution, and their respective guardians.
