The opening logo is red in "Brothers" and "Revenge" rather than the traditional yellow.
The word 'brother' is spoken 16 times, 9 of which are uttered by Savage Opress.
The 'Jedi fortune cookie' message that opens the show reads "The enemy of my enemy is my friend."
The 2020 anthology book "Star Wars The Clone Wars: Stories of Light and Dark" features a story based on "Brothers" and "Revenge" that is told from Darth Maul's point of view. It is written by Rebecca Roanhorse and titled "Dark Vengeance". The audio-book version is read by Clone Wars voice actor Sam Witwer.
