Teddy finds it hard to make the last diary special. Amy is trying to get herself a full-time job on Good Morning Denver since the leading lady is leaving the show. Gabe and Mrs. Dabney attempt to stop the new kid Matt, from pranking her. PJ and his friend Gravy try to have a food truck and sell Fish and Gravy, but PJ doesn't think it is a good idea. PJ then gets the truck for himself, and Bob gets to work with PJ selling peanut butter and jelly sandwiches which everyone finds excellent.
Bob and Charlie know Spencer is back in town, and Teddy wants him at her going away party. Spencer said he'd think about it and then comes along with Victor, Skyler, Emmett, Mrs. Dabney, Lauren, and Vonnie comes to say goodbye. Teddy and Spencer sing a song because Charlie wants them to.
The next day, when Spencer visits the Duncans because he left his jacket, Teddy and Spencer figure their colleges are not so far away from each other, and they should meet up as friends. Before Spencer leaves, they kiss twice and end up back together.
Everyone then gets rid of their new neighbors with a marching band practice which they would have every day. Mrs. Dabney sees that Toby will be the next "devil child." The series ends with Teddy making the last video diary with the whole family, and they say together, Good Luck Charlie, also joined by Charlie.
