When Cad Bane is arrested, he is arrested by a Coruscant royal guard clone trooper (red color on armor) however when he discovers Hardeen is actually Obi Wan, the guard is now a regular clone (no red color).
Cad Bane has been previously shown to require a special apparatus in order to breathe in an oxygenated atmosphere. The apparatus is missing in this story, yet he suffers no ill consequences.
