Smallville - Season 10 Episode 7

Clark is far from impressed that Lois barely dares rebuke her kid sister's mean pranks on both of them, while squirming for each, even offensive, whim of Pa, full general Sam Lane, as their Thanksgiving guest. Clark firmly but politely hosts the Lanes, while reasoning against the general's support for a bill to make 'registration' compulsory for superheroes, an obvious trap given the congressional supporters' antecedents. While Oliver investigates them, Clark saves everybody from proponent Rick Flag's Machiavellian rocket attempt on the general's life. Only when Lois finally sides with Clark against Pa, he reveal his ulterior motive for exaggerated rudeness.
