John accepts bionic reconstruction of his face in exchange for working as an F.D.A. agent. Mike Applebee takes particular glee in pairing Tony and John as partners. Applebee sends the agents to investigate a bank robbery where the perpetrator left a pile of fecal material. The agents make a side trip to visit D-Bear -- just for old-time's sake. John processes a boatload of data, deduces the perpetrator, and the boys make the collar. But at the crime scene, Tony tastes the chicken gumbo and finds something unexpected.
