This is the first episode in the entire series dealing with the method by which Gems are corrupted, and is also the first episode dealing directly with White Diamond's actions during the rebellion.
Centipeedle's humanoid form is wearing a uniform with decals on the arms and legs quite similar to Pearl's space suit in "Space Race" (S01E28). Pearl's space suit in that episode is white and features a pink diamond in the center, which either represents Rose Quartz, her direct superior, or Pink Diamond, Rose Quartz's former superior officer. Unfortunately, Centi's uniform is covered by an errant strip of cloth where her insignia would be, meaning the audience can't know for sure from this episode who Centi's Diamond was.
