Favorite Side Story

While the overall arc of the show was great, there were so many great 'filler' or standalone stories that were fun to watch and re-watch. What are some of your favorite standalone / side stories from the show?

'Faith' was one of my favorites early on. The brothers were still a bit young in their career. Still not sure of how to handle every situation. It showed the desperation from the brothers to always be trying to save each other. The aesthetic of this episode was just right.
