S3:E10 - To Save Us All From Satan's Power

In our first Yuletide set Sopranos episode, we get several revealing flashbacks in which Tony is haunted by ghosts of Christmas past. As Gavin and Hannibal observe, “To Save Us All From Satan’s Power” displays tremendous depth in its approach to referencing past events, and setting up future ones. It also gives insight into how mobsters emotionally process the experience of being betrayed by one of their own.
