Joe is thinking about the world ending, whether that is by anthrax attack or falling clouds - and he wants to explore his feelings with Darren's help. An intercepted communication sparks a debate over what technology the gards use to communicate, after which absolutely nobody is willing to admit defeat. Darren considers a career in old school stand up comedy, and he's been doing Bono impressions at the dentist. Plus he's worried a fly infestation in his apartment means the haunting he has hoped for has come true, but Joe thinks the true cause could be far more mundane, and disturbing.
