Endora intimates that there'll be trouble in store for Darrin when he refuses to allow Samantha to accompany him on a business trip to Egypt. Upon his arrival, Darrin discovers that his new assistant, Gideon Whitsett (Jonathan Daly), is ruthlessly jockeying for Darrin's job. What he doesn't know is that Gideon is a warlock, summoned by Endora to gum up the works. Written by Joanna Lee, "Your Witch Is Showing" first aired on February 4, 1965. ~ Hal Erickson, Rovi
