Thom and Cal attend an "end of the world" party (featuring guest star Stephen Guarino), where spirits are consumed ... and a demon is confronted.
Actually, the demon that's confronted is not the perpetually shirtless Jeremy, but what he represents, as Cal tries to drown his sorrows, and a bordering-on-callous Thom tries to diffuse the relationship bombs he's juggling.
Meanwhile, we meet new character Ian (John Halbach), who is Kathy's easygoing boyfriend, and will wish it was the end of the world by the time the episode ends
