Clemens and Fennell decided to film a new episode to introduce Tara King. This, the third episode filmed for the sixth series, was titled "The Forget-Me-Knot" and bade farewell to Emma Peel and introduced her successor, a trained but inexperienced agent named Tara King. It would be broadcast as the first episode of the sixth series. Tara debuts in dynamic style: when Steed is called to Headquarters, he is attacked and knocked down by trainee agent King, who mistakes him for her training partner.
