Nan struggles with a breakup and Martin's bad behaviour, as he acts out in response to her newly busy work schedule.

When Nan installs an automatic dog door so Jason can still walk Martin, Martin believes he's using his mind to open the door; Nan's boss spirals into confusion as he struggles to understand the new ad campaign she sold.

Nan brings Martin to work with her, hoping to keep her boss from further interfering in her ad campaign.

Hoping to score a date, Nan asks an attractive dog owner for help with Martin; the man's better-behaved pooch inspires a crisis of self-confidence in Martin.

When Nan, Jenn and Kevin travel to New York for a marketing meeting, Martin takes advantage of his time with Jason by going on a trash-eating bender.

Martin's seventh birthday is disrupted by the arrival of Nan's friend Jenn and her new puppy; Nan and Jenn go out for a night on the town.
