The scene where Parker is testing Breanna with a jacket covered in bells is an old pickpocket tradition to train young pickpockets. Guilds of pickpockets would test new members by attaching each pocket of a jacket with a bell and putting it on a dummy. The pickpocket in training would have to remove an object from a pocket on the jacket without disturbing a bell.
Parker (Beth Riesgraf) names the vault on the riverboat as a Boylan-Kim. Christine Boylan was a writer and executive story editor and Albert Kim was a writer for Leverage (2008). Usually the vaults and safes are named Glenn-Reider after Leverage writers Melissa Glenn and Jessica Rieder.
