One of the few episodes to date that doesn't have the opening title sequence with palm trees and opening theme of "Kings & Queens" by ChinChin. Instead it contains the title 'The Rookie' with the title in red.
Raphael Sbarge joins the list of Once Upon a Time alumni to guest-star on The Rookie, alongside Mekia Cox (Harper) who played main character Princess Tiana/Sabine and several episode guest-stars and minor recurring characters. Interestingly, the most recent major actor crossover was in another episode set mainly in the same hospital (episode 3x12, "Brave Heart") and featured the actor who played Sbarge's character's closest friend; Tony Amendola played the dying druglord Madrigal in that episode and Gepetto/Marco in Once, Sbarge played Jiminy Cricket/Dr. Hopper in Once.
