Inside the Episode: Learn more about Tiffany & Nica's return, Fiona Dourif's Chucky transformation in Ep. 5, 'Little Little Lies'

It was a monumental week for SYFY & USA's Chucky, as Episode 5, titled "Little Little Lies," saw the return of two not-so-little characters in the franchise: Tiffany Valentine and Nica Pierce. In this week's installment of Inside the Episode, we go behind the scenes and hear from Jennifer Tilly (Tiffany) and Fiona Dourif (Nica/Chucky) as they discuss their blood-curdling return to their Chucky roots. We also hear from creator Don Mancini and actors Zackary Arthur and Björgvin Arnarson, who talk about filming Jake and Devon's much-anticipated first kiss and what it took to get the scene just right.

Watch Dourif and Tilly break down their series debut together, which includes a not-so-subtle sex scene and (yep, you guessed it) murder. "It's so much fun to be back," Tilly says. "When I put on my Tiffany wig, I was like, 'Oh, there you are!' And of course, the fans go crazy."

We also get a glimpse into Dourif's transformation into the young Charles Lee Ray, who she strikes an eerily similar resemblance to — probably because her father, Brad Dourif, is that character's original actor and the voice of Chucky. "I was thinking of who would be perfect to play the young Charles Lee Ray," Mancini says. "The answer was right in front of my face."

Watch all of that and more in this week's installment of "Inside the Episode," and be sure to check back for more content after each new episode of Chucky airs on Tues. nights at 10/9c. Remember, he's your friend 'til the end.
