‘A Discovery of Witches’ Season 3 Episode 3: Diana Makes a Discovery

Diana and Matthew are separated by an ocean in the latest episode of A Discovery of Witches (streaming now on AMC+, Sundance Now, and Shudder). But being apart might be a good thing, because it allows each to take a big step forward when it comes to finding the thing they’re searching for. In Matthew’s case, that’s the still-elusive cure for blood rage. In Diana’s, it’s the missing pages of the Book of Life.

Matthew (Matthew Goode), Marcus (Edward Bluemel), and Jack Blackfriars (Toby Regbo) spend this episode in the Big Easy, where Marcus’ surviving vampire children live. But they aren’t exactly welcomed with open arms. 

Matthew’s decision to kill off those vampires infected with blood rage has left the survivors bitter and distrustful, especially their leader Ransome (Parker Sawyers). Jack’s presence is just salt in the wound, given that Matthew has decided to let him live, even though he also suffers from the disease that causes infected vampires to fly into unpredictable – and bloodthirsty – rages. 

Still, Matthew and Marcus have no choice but to attempt to heal the rift. They need this group of vampires to join their new scion as they go up against the Congregation. And they need samples of their DNA in order to get a better understanding of what causes blood rage and how to treat it. 

Eventually, Matthew engineers a meeting with Ransome, where the younger vampire blows up at Matthew for killing both his friends and the woman he loved. Matthew offers a half-hearted apology, but Ransome demands an expression of genuine remorse for what he’s done. So, Matthew mournfully lists off the names of all the vampires he culled. 

“I see what I did and I can’t change it,” he says. “And I am truly sorry about that.”

The apology satisfies Ransome, who agrees to join Matthew’s new scion.    

Diana gets closer to discovering the Book of Life’s secrets

While Matthew is reflecting on his past mistakes in America, Diana (Teresa Palmer) is in London searching for the two other missing pages of the Book of Life. They already have the witch’s page, and they suspect that one must have been given to the vampires. The third is likely in the hands of the daemons. 

With some help from Phoebe (Adelle Leonce), Diana figures out that another manuscript might contain clues that could point them to Ashmole 782’s missing pages. That book, in turn, leads her to Father Hubbard (Paul Rhys). Unfortunately, disgraced witch Peter Knox (Owen Teale) gets there first. He tries to force the priest to give up the page, but Hubbard tells him to get lost. 

Hubbard does give the page to Diana. But he only agrees to hand it over after she explains that if either Knox or Gerbert (Trevor Eve) get their hands on it, they’ll use it to further divide the creature community, which puts his flock at risk. Getting the page is a major coup for Diana, and by the episode’s end, she and Phoebe also have a good idea of where the third page might be. 

Gerbert and Benjamin plot against Matthew and Diana 

Matthew and Diana are making progress in their efforts to stand up to the Congregation and promote equality between all creatures. But their enemies haven’t given up the fight. 

Knox might have been kicked out of the Congregation, but he still poses a serious threat. Meanwhile, Gerbert and Benjamin (Jacob Ifan) are biding their time on the sidelines. Gerbert assures Benjamin that the best plan is to watch and wait while Matthew’s feud with his brother Baldwin (Peter McDonald) plays out. He argues that the conflict will weaken the De Clermont family. But Benjamin is eager to make an outright attack on the vampire who sired him and his pregnant witch wife.

Finally, there’s Satu (Malin Buska). Benjamin pays her a visit at the end of the episode and proposes an alliance. But Satu – who is also a weaver – wants to take on Diana on her own terms. She believes the prophecy from season 1 actually referred to her,​​ not Diana. So, could Satu be the witch “with the blood of the lion and the wolf” who will destroy the vampires? Viewers may find out in the next episode of A Discovery of Witches Season 3, which streams Saturday, Jan. 29 on AMC+, Sundance Now, and Shudder.
