I sort of expected that, though I would never admit it aloud in fear of tempting fate.
He is too good-hearted a person to get over a thing like that so easily. If the press and JSF made him believe that he is "worthless", then nothing short of turning back time could stop him from hating himself.
For him, skating was not to get medals, but to share his joy and love of skating, and to see happy faces in audience was his greatest happiness. Now when he probably believes that people are angry at him or hate him, how he is supposed to skate in front of those people?
Some of the Japanese articles really painted him as the heart of blackest evil, twisting facts to add more dramatics. There were a few trolls that appeared on figure skating message boards and saying that Nobu should be banned from competing forever, and that if he appears at Nationals, they will throw stones at him. Judging by the language they used, they were most probably jealous teenagers, but if Nobu read some of the messages (which were sent to his blog, too), then it is very probable that he thought that if he does skate in Nationals, people will hate him even more, that they will treat it as act of stubborness and lack of humility, as laughing in the face of victims of all car crashes.
I'm beyond devastated for him - I'm afraid that torn between wanting to please fans/JSF/coaches through competing and cleaning the family name; and between wanting to please his haters through disappearing from the public - he will chose the only way to reconcile those two options and commit suicide.
I just do not have words.
I do, however, have a few words that I would like to tell to JSF, most preferably supported with a more physical expression of my distaste. First they treat him as a piece of trash that got stuck to their shoes - and now they are disappointed that they will lose 3 spots? Have they no heart or imagination? ...Rhetorical question, I know.
