In contrast to the Gale episodes, there is a lighter, comic touch in Steed's and Peel's interactions with each other and their reactions to other characters and situations. Earlier series had a harder tone, with the Gale era including some quite serious espionage dramas. This almost completely disappeared as Steed and Peel visibly enjoy topping each other's witticisms. The layer of conflict with Gale—who on occasion openly resented being used by Steed, often without her permission—is absent from Steed's interaction with Peel. Also, the sexual tension between Steed and Gale is quite different from the tension between Steed and Peel. In both cases, the exact relationship between the partners is left ambiguous, although they seemed to have "carte blanche" to visit each other's homes whenever they please, and it is not uncommon for scenes to suggest that Steed had spent the night at Gale's or Peel's home, or vice versa. Although nothing "improper" is displayed, the close chemistry between Steed and Peel constantly suggests intimacy between the two.
