Chosen answer: SPOILER ALERT: It was the 1970's. Loose morals. The era of free love. Little Bill and his wife were active in the porn industry. It's likely that his wife presumed, but never discussed with her husband, an "open relationship." Bill, stunned by his discovery (but, perhaps, suspecting it all along), was simply trying to maintain his composure and not seem pathetically unhip by what would be perceived as an absurd overreaction. Clearly, however, he was suppressing a great deal of internalized rage. Ultimately, but very calmly as always, he eventually shoots and kills his wife and her gentleman caller mid-coitus, and then eats his own gun, at Jack's New Year's Eve Party, 1980.
