Originally, Wyndam - Pryce was supposed to be killed off in the season 3 finale but, due to Whedon's surprise at how well he fit into the series, Denisof was given the choice about his character's fate and chose for him to live . As a result, he later showed up in season one, episode 10 of Angel, and was an official main cast member from episode 11 (effectively replacing Doyle), appearing in 100 out of the 110 episodes of the series .
