I think we have finally talked him into talking with a lawyer once he returns from the funeral about all of this. I told him that he literally can't run forever.
He is still REALLY worried about getting caught flying though. I tried to reassure him with all of what you guys said though. He is still afraid somehow someone out there will cross reference his name and birthdate with some list and find him. I told him thousands and thousands of people fly every single day and not to worry about that so much.
