Update:
Cue 'breakfast club' closing music.
The captain's actual identity was revealed by 'apostate hunters' from Canada, that's what the elder visit was about apparently. They printed off all of his posts from here and physically sent them to his elders.
Confronted with his alter ego's postings in black and white he narrowly avoided being df'd and agreed to shut up about his doubts.
Four years later Mrs Blithering woke up, and she and the captain sailed away into the sunset, undf'd and with family intact.
The nice investigating elder is also out, with his family, having realised it's a crock too.
