Heading into the fourth episode of the James Wan-produced “Swamp Thing,” Abby Arcane is now fully aware that the monster is the deceased Alec Holland, while Holland/Swamp Thing has found himself in control of the mysterious (and sometimes quite evil) forces of the swamp. What’s next? This Friday’s episode looks to be taking things into Shape of Water territory!

In “Darkness on the Edge of Town”…

“Realizing that his new abilities allow him to communicate with the life around him, Swamp Thing senses a growing darkness within the swamp and begins to understand his role in the struggle for balance between growth and decay.”

“Abby, meanwhile, is forced to accept that the things she has witnessed in Marais are evidence of supernatural forces at play – especially when her return dredges up her dark history with the Sunderlands. And Liz shares some evidence with Sheriff Cable about her investigation into the death of Alec Holland. Lastly, we learn more about the mysterious Daniel Cassidy and the supernatural bargain that keeps him in Marais.”

The new episode premieres Friday, June 21st on the DC Universe streaming service.
