After countless times of babysitting Deacon and Kelly's children, Doug and Carrie feel that Deacon and Kelly should return the favor and babysit Arthur every once in a while. Deacon and Kelly decide to take Arthur out to dinner so Doug and Carrie can be alone, but they ignore a warning about Arthur's reaction to spicy food.

It's Thanksgiving in the Heffernan household and while Carrie cooks dinner for ten people, Doug lets a stranger into the house to use the phone. He is convinced the stranger is a nice guy but Carrie is not so trusting. Everyone at dinner feels sorry for the man, who's been left outside to wait for a ride, but when Carrie finally gives into the holiday spirit, it turns out her instincts may have been right.

Doug lies to Carrie and tells her that he regrets not accomplishing more in life and that he's going to sign up for the IPS management program. As part of his new outlook on life, he tells Carrie that he also he needs to conquer a local rollercoaster called "Goliath."

One night at the movie theatre, Doug and Carrie can't decide on which film they want to see. They run into Deacon and Kelly and it turns out Kelly wants to see what Doug wants to see and Deacon likes the movie that Carrie likes.

In the landmark 100th episode of "Without a Trace," the team searches for a family man, Aaron Gibbs (ERIK LA SALLE - "ER," "One Hour Photo"), who has been emotionally haunted and financially harmed by living through and being displaced by Hurricane Katrina. Aaron's wife, Sherise (LISA GAY HAMILTON - "The Practice," "The Sum of All Fears"), tells the investigators that she last saw Aaron the previous morning when he left their Queens motel room. Supposedly, Aaron had gotten a temporary construction job in New Jersey after being fired from a construction job with his cousin, Chuck Barr (MICHAEL BEACH - "Third Watch," "ER"). But the team learns that Aaron, whose truck was found abandoned and burned, actually quit his cousin's job and lied about having found work in New Jersey. Wondering what else Aaron may have been hiding from his wife, the agents entertain theories of foul play and suicide, as well as the possibility that Aaron chose to run away from his mounting financial woes.
