Maybe....maybe his loyalty is to her and her/their reputation, nothing else. Young love and those passions. Maybe something happened that would be terribly, horrifically embarrassing to her/him/them and he is protecting her by disappearing. I know we have clips of dissention, but we also have a regular, consistent history of love reflected in pictures, and videos, too.
I think it's too easy to presume his guilt. It is harder to pretend you are on a jury where he IS presumed innocent, if he is in fact ever charged with such a crime. And he may be guilty of this horror, but someone else may be, too...if he is innocent, maybe he is waiting for that other to be found....if not, I am convinced he is dead, likely from guilt. MOO.
