"The others were saying that he died serving Reign, that--that he's a martyr. They'd become fanatics."
Tanya Spears on the Cult of Yuda Kal
"The Fanatical" is the nineteenth episode of the third season of Supergirl, and the sixty-first episode overall. It aired on May 21, 2018.


When Tanya, a disciple of Coville's, escapes from what’s left of his cult, she gives Kara and James a journal that could hold the key to saving Sam. Someone learns Guardian’s identity and threatens to expose James if he doesn’t do what they ask. James contemplates what it means to be a black vigilante without a mask in America.[1]


  • In the beginning of the episode, Lena mentions the ability to override genes in crops through a biolistic delivery system by coating particles of heavy metal in DNA and delivering them into the cells' interiors. This exists in real life and is also known as a gene gun.
  • The arcade that J'onn, Alex, Ruby, and M'yrnn go to is called Fun Centre. The Canadian spelling is a nod to the fact that the show is filmed in Vancouver, Canada.
  • The getaway car that the cult members use to kidnap Tanya has a license plate reading "590 WUG". Tanya is a linguistics professor, so this is likely a reference to wugs, small cartoonish birds used in a famous linguistics experiment on child language acquisition that are popularly used as a symbol for the field of linguistics.
  • When James considers revealing his identity as Guardian at a live press conference to throw off the cult's plan, Winn likens it to the 1996 film Ransom, in which the main character turns the tables on his son's kidnappers by using the ransom money to place a bounty on their heads on live television.
