Starring: Malcolm Goodwin, Rose McIver, David Anders, Rahul Kohli, Robert Buckley
Johnny Frost: Frankly, I resent being questioned every time a hooker or stripper or dominatrix gets killed in this town. Why don't you ever bug me when somebody murders a plumber?
Detective Babineaux: You hang out with a lot of plumbers?
Johnny Frost: That was rhetorical. Look, hookers, strippers, yeah. But a dominatrix? I'm a married man, Detective. I already give way too much of my money to a woman who abuses me.
Real Dead Housewife of Seattle - S2-E3
Trivia: Liv says to her roommate "a long time ago we used to be friends," talking about her former roommate Peyton who is now back in Seattle. This is a direct homage to the lyrics to the theme song from Veronica Mars (created by Rob Thomas, who also created iZombie).
