B:TB&tB season 2 episode 15 "The Siege of Starro!: Part 2" Directed by Michael Goguen.
For a lighthearted show, Brave and Bold touched on death more than a couple of times in the second season. After the big climactic battle of this episode, we wanted to have the backgrounds to have a more somber and reflective tone.
