After focusing on the ordeals of Vanessa (Eva Green) in the previous episode, the fifth episode (entitled “The World Is Our Hell”) in the third season of “Penny Dreadful” will shift its focus to Ethan and Hecate as the two endure the scorching temperature and stark landscape of the desert wasteland they are in.

In the 45-second promo video released for the episode, Hecate (Sarah Greene) is shown questioning Ethan (Josh Harnett) as to the reason why he is being hunted down by his own father. Ethan, although hesitant at first, admitted that he killed his friend and went against his family’s wishes. He also said that he plans to send his father to hell.

On the other hand, Dr. Victor Frankenstein (Harry Treadaway), is seen testing out his science expertise on another test subject, which in this case, looks like an older man.  

The episode fits what show runner John Logan told Entertainment Weekly earlier about Season 3 explaining more of Ethan’s past, including how he became a werewolf and how he fell out with his family.

Logan, who also serves as an executive producer of the paranormal thriller, credits this plot thread as the reason for bringing Ethan back home to the United States as it is where he grew up.

“I’ve always loved Westerns,” he said. “And I’ve always known, from the beginning of the series, that I wanted to take Ethan back home for a final reckoning with his demonic father, who Brian Cox plays later in the season, brilliantly.”

Sebastian Croft, who plays Boy Familiar in the show, recently posted a picture of him chilling out behind the scenes with fellow actor Jack Greenless.

“Vampire taking a break on set,” he wrote, adding the hashtags #CreepyVampireBoy, #PennyDreadful, #BoyFamiliar and #LeadFamiliar.

“Penny Dreadful” airs every Sunday on Showtime.
