- Royal Brat: Averted with Perdita. Throughout the entire short she was brave, calm, helpful, and serious.
- Royals Who Actually Do Something: Princess Perdita keeps her head during the assassination attempt, and even applies a field bandage to Green Arrow when he's wounded by one of Merlyn's arrows.
- Shipper on Deck: From Perdita's encouragement to Black Canary to say "yes" to Green Arrow's proposal, it appears that she ships the two.
