I actually had a hard time understanding this. Can anyone explain? I felt like it was just kind of tacked on at the end - "Oh, he's always been psychic." But why were certain people chosen to be saved?
For some reason he doesn't realize he's psychic at the beginning and thinks a higher power is controlling him. So this psychic stuff only happens every so often. But then somehow Holly wanting him to save more people on the plane expounds his ability and he guides the plane down to save more. IDK....kind of weird when I think back on it and how it all makes sense. I feel like it's something I'd have to read again having the ending in mind.
Jim actually tasked himself to save these people somehow. We never know if they truly became the greatness The Friend explained they would be. Holly's presence on the plane altered the outcome, pushing Jim further in using his psychic abilities (diagnosing the planes malfunction, landing the plane, etc) and being a savior if you will for Jim himself. He would have likely died without her.
Question modified - sorry!
