He made you a Ronin... (15.21)

Bryan: Axelrod banished you. He made you a Ronin. I'm willing to bet he didn't give it a moment's thought, while you've been thinking about it every second of the day, suffering from something you've never felt before. Doubt. And all because you pledged yourself to an unworthy lord. Axelrod lacks five of the eight virtues of the Bushido.

Gus: Six. Oftentimes, he wasn't even polite.

Bryan: Under these circumstances, honor doesn't demand silence or self-harm. It demands vengeance.

A rōnin (浪人, "drifter" or "wanderer”) was a samurai without a lord or master during the feudal period (1185–1868) of Japan. A samurai became masterless from the death or fall of his master, or after the loss of his master's favor or privilege.

In modern Japanese usage, sometimes the term is used to describe a salaryman who is unemployed or a secondary school graduate who has not yet been admitted to university.
