"Fire Walks with Z" is a reference to 1992's "Twin Peaks: Fire Walk with Me," the prequel to the television series "Twin Peaks," and follows the last seven days of the life of Laura Palmer (Sheryl Lee), whose death kicks off the original show's plot. The film is directed by David Lynch, who co-created "Twin Peaks" with Mark Frost. Outside of "Twin Peaks," Lynch is a renowned filmmaker, having directed classic films such as 1977's "Eraserhead," 1986's "Blue Velvet," and 2001's "Mulholland Drive."

As it turns out, the "Gossip Girl" episode based on the title of Lynch's film was actually directed by his daughter, Jennifer Lynch. The younger Lynch has been directing since the late '90s and has helmed episodes of several popular TV series, such as "Psych," "Quantico," and "American Horror Story." Along with "Fire Walks with Z," she also directed the third episode of the "Gossip Girl" reboot, "Lies Wide Shut."

We can't wait to see if "Gossip Girl" cleverly plays with their film reference titles again throughout its run.
