I think you might be projecting. According the the parents, they did not want Shawn there but he asked to go. The decision was left up to him.
Well, that's odd because he refused to utter a single word when he got there. Maybe he volunteered to go because he didn't want to be alone with his parents, maybe it was just too awkward. Who knows?
I am a little puzzled about his parents. They showed a film clip from the time that Shawn was first abducted of a nice looking man in a beard, talking about Shawn, was that his real father? It doesn't look anything like the guy with the horrible teeth that was seen at the school.
By the way, why the nasty personal remark? Why do you feel the need to attack?
"The decision was left up to him"
Someone needs to call these parents, and tell them that they need to protect their son, not turn him into a media sideshow. This kid has been playing a role for 4 years. His parents haven't figured out that what he says he wants to do, may not be in his best interest.
