"Regardless, the conversation returns to Casablanca. Vance recites a story about a single shot that director Michael Curtiz needed for the film. It’s just a nod, but as Vance describes, it’s a pivotal point in the story. It’s the moment when Rick takes sides. Vance, in essence, gives Gibbs the direction for the same sort of call. He can take sides. He can do what he needs to do regarding Rivera, no questions asked. Gibbs doesn’t nod. He shakes his head. As they walk away, the shot resembles the ending of Casablanca, with the unspoken final line: “Louis, I think this is the beginning of a beautiful friendship.” Considering the animosity that has existed between Gibbs and Vance, they’ve come along way."
