|Episode||Sisters at Heart|
Mr. Brockway is a prospective client of McMann & Tate who is a secret racist. When Lisa Wilson answers the door at the Stephens' house, Mr. Brockway thinks she is Darrin's daughter, thus the child of a mixed race marriage. He tells Larry he wants Darrin off of his account.
When Mr. Brockway later discovers his error and wants Darrin back on the account, Larry tells him they are not interested and to take his business elsewhere.
Later, when visiting the Stephens house, Samantha casts a spell so he can see everyone - including his mirror reflection - with dark skin and he leaves. The next day, he admits his problems and apologizes. Samantha invites him to stay for dinner.
