Our Very First Show, Again

Nicky has been attending College in San Francisco with his brother Alex, for the past 6 years. They plan to graduate, move to LA and open a Fish Taco Truck together. But until they 'hit it big' they are going to move back in with their parents, who are not too pleased with that idea.

Fuller Thanksgiving

Nicky attends Thanksgiving at The Tanner House with his family. He brings fish tacos from his Fish Taco Truck that he co-owns with his twin brother Alex (that their dad paid for) in Los Angeles. No one eats the tacos because the fridge in the Fish Taco Truck is broken.

While D.J. and Matt prepare Thanksgiving dinner, Nicky, Jesse, Danny, Joey, Stephanie, Becky, Kimmy, Jackson, Ramona, Max, Tommy Jr., Fernando, Alex, Jimmy, Ginger, Phyllis, Jerry, Joan, Lewis and Cosmo are out playing football. 

Nicky and Alex sit at the children's table for Thanksgiving dinner. Nicky complains to Becky that Alex is kicking him under the table.
