In the scene shortly after David wakes up and is escorted by the police to where his family currently lives, can you imagine what the dad is thinking when he sees his son run up to him who 1) disappeared 8 years before and was declared legally dead and 2) has not aged one second from that night. I'd be wondering who all of a sudden changed the rules.
