Duel of Honor (1x7)

:

When an Italian Count arrives in North Fork, his strange attire attracts the attention of Groder, a town bully. Groder trying to have fun with this stranger, destroys some of the Counts currency, mocks him, and tries to humiliate him. Eventually the Count challenges Groder to a duel and asks Lucas to be his Second. They meet at dawn and the Count, the offended party, brings his single shot dueling pistols, something Groder is unaccustomed to. Lucas as second must see that all rules of the duel are adhered to.
