When Anna-Kat brings home a lice infestation, Katie uses it to force bonding time with Taylor. Greg attempts to bond with Oliver (and avoid lice) by camping in the backyard, but Greg becomes concerned when Oliver keeps ditching their campout to be with their new sleazy neighbor named Spencer.

Katie and Greg dislike Taylor's new boyfriend, so they attempt to use reverse psychology to drive a wedge between them, which later backfires. After Spencer's over-the-top vision for Oliver's first date with a girl from his ballet class bombs, Greg helps Oliver make up for it with a romantic gesture.

In order to impress the other moms at school, Katie, Taylor and Oliver travel to New York to track down Nathan Fillion at a "Firefly" convention, so Katie can convince him to attend the school's spring gala.
