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.

Greg plays dirty to convince Katie to let them keep Anna-Kat's beloved pet pig; Oliver and Viv compete for the attention of a new neighbor; Taylor considers leaving her boyfriend.

Greg makes big plans to impress his parents when they visit for Thanksgiving; but his vision is shattered when his neighbor Spencer and Katie’s mom, Kathryn, arrive unannounced and nothing goes as intended.

Katie is worried that the launch of Greg's new book might go poorly, so she enlists Angela and Doris to write positive reviews; when the book unexpectedly does exceedingly well, Greg buys a new car without consulting Katie.

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.

Katie and Greg struggle to help the kids accept loss as a family friend suddenly passes away and as their pet pig, Hans Gruber, must be returned to his natural habitat.
