Attending a Mardi Gras festivity, Claire recognizes Robert Latour in the crowd, and points him out to Charles, who is quick to challenge Robert to a duel. Robert gets to choose weapons, and he chooses knives, something Charles isn't quite prepared for. Robert gets a distinct advantage over Charles in the duel, and Claire steps in to interrupt what she fears will be the end of the banker's life. She tells Charles that she mistook Robert for someone else, thus ending the battle.
