Which subtitle follows "Chapter 3:" in The Mandalorian?

The subtitle following “Chapter 3:” in The Mandalorian is “The Sin.” It is the third episode of the first season and was written by series creator Jon Favreau and directed by Deborah Chow.

In the episode, Din Djarin delivers the Child to the Client, receives a valuable beskar reward, and begins questioning the consequences of abandoning his young charge. He later returns to rescue the Child, turning what initially appears to be a routine bounty assignment into the central protective relationship of the series.

The title is easy to confuse with nearby episode names. “The Child” is Chapter 2, while “Sanctuary” is Chapter 4. “The Sin” refers to the moral transgression at the episode’s center, as Djarin and the other bounty hunters confront the cost of treating the Child as merely a target.
