This episode features the following exchange between Lenore Case and Britt Reid regarding Reid's sister Susan, his only known sibling:
CASE: And here is the mail. There is a letter here from your sister at college.
BRITT: Susan? Well what's possessed her to write? Let's see it.
CASE: She's been reading of this Green Hornet. Says that when she comes home for vacation she's going to spend the time with you and play detective with Michael Axford and try and make a sensational capture.
BRITT: (laughs) She probably wants that reward.
CASE: The easiest way for her not to come close is to work with Axford.
