As he did for most of the original "Avengers" series, John Steed is once again acting without a direct superior—in many ways his character takes on the duties of "Mother" from the Tara King era of that series. Steed is seen to be the mentor to Mike Gambit and Purdey, taking on a paternal role towards them (especially in the episode "Hostage"). Gambit is the athletic action hero, while Purdey incorporates the wit and fighting skills of her predecessors. The verbal interplay between Gambit and Purdey, with her humorously keeping his romantic advances at bay, harks back to the Steed/Cathy Gale era of "The Avengers".
