 Kingsfield s character and background are further developed in this episode: his own days as a student at the law school, hanging out at Ernie s in the 1930 s, and his friendship, then, with Ernie Sr. However, now Ernie s is threatened with closure. The entire block, owned by the university, is to be razed to enable construction of a new gym and a parking lot. Ernie can t afford to hire a lawyer to fight the university and Hart takes on the job -- only to learn that his adversary is Kingsfield, representing the university. Bravely, Hart confronts Kingsfield and appeals to him, only to be rebuffed by his professor. But Kingsfield s nostalgic memories are sparked by the encounter and he visits Ernie s, there encountering Ernie Sr., who s visiting his son. While they talk, Kingsfield discovers something that might save the bar from being torn down. Later, Kingsfield craftily drops suggestive hints to Hart without revealing that his aim is to guide Hart into making the same discovery. At the last moment Hart finds proof that the building was built in 1774 and is eligible to be named an historic monument, thus illegal to tear down. This saves Ernie s, the law students are happy, and Kingsfield is satisfied that his mentoring, though covert, worked..
