The new girl in town on The Testaments is already causing problems for Gilead’s girls and providing fodder for theories IRL. Who is Daisy and what is her deal?! The show is making a major change to Margaret Atwood’s follow-up to The Handmaid’s Tale, so let’s get into it.

Lucy Halliday’s character on The Testaments first appears as a “Pearl Girl” immigrant from Canada. These young women are converts to Gilead’s fundamentalist religion. Agnes (Chase Infiniti) and her classmates at school are suspicious of Pearl Girls, as they tend to be more devout and loyal to Aunt Lydia (Ann Dowd) than they are. But when Daisy gets her first taste of Gilead’s violence, she’s horrified. The mask begins to fall. We learn, over The Testaments’ three-part premiere, that she is a spy for May Day sent by June Osborne (Elisabeth Moss) to help take Gilead down.

Daisy joins the fight after her parents Neil and Melanie, who she later learns are adoptive, are murdered by Gilead. In a flashback, June tells Daisy that she was born in Gilead and therefore its government wants her back. By becoming a spy, she’s essentially hiding in plain sight. That said, orphan savior? I’ve heard that one before. But like Harry Potter and Luke Skywalker before her, does this mean her biological parents are significant? Let’s get into it.

This is a major change from The Testaments’ source material:

In Atwood’s novel The Testaments––seriously, major major major book spoilers ahead––Daisy is a grown-up Nichole Waterford, a.k.a. Holly Osborne, a.k.a. the biological daughter of June and her guardian/lover Nick Blaine (Max Minghella). That also makes her half-sisters with Hannah, June’s grown-ish daughter with Luke (O-T Fagbenle). TV show spoilers ahead now, but if you read Atwood’s books or watched the final seasons of The Handmaid’s Tale, you know that Hannah is now known as Agnes Mackenzie and played by Chase Infiniti on The Testaments.

Just like on the show, Daisy was adopted by Toronto residents named Neil and Melanie. Just like on the show, she was sent to Gilead as a Mayday spy after their untimely death. FWIW, Halliday also looks an awful lot like Moss. June has intimate knowledge of how Daisy came to be in Toronto.

But the details don’t 100 percent match. June and her younger daughter went from Canada to Alaska and back to Boston in the last two seasons of The Handmaid’s Tale. Would June really send Baby Nichole back into Gilead as a spy?

Unfortunately, the series is not going to become June’s biological daughters vs. Gilead like it is in the book. Showrunner Bruce Miller confirmed to TV Insider that Daisy is not Nichole on The Testaments TV series. This adaptive change was, according to Miller, partially to justify having Daisy and Hannah/Agnes be closer in age and attending school together.

According to this theory, Daisy could be a different part of The Handmaid’s Tale history

Some fans are suggesting that Daisy is one of the infant refugees that June and an underground network of Marthas smuggled to Canada in an operation called Angel’s Flight at the end of The Handmaid’s Tale season 3. Reuniting families who Gilead had separated and getting as many young children out of the regime’s clutches in general was a major priority for June as she grew into her role as activist and rebel on the original series.

That still doesn’t quite add up with the television show’s timeline. Another big adaptive change between the book and the series is that The Testaments television show takes place only four years after the end of The Handmaid’s Tale, and the novel takes place 15 years later. A baby smuggled out at the end of The Handmaid’s Tale season 3 would probably not be a teenager already!

Could she be the secret daughter of another character? Most of the handmaids’ were reunited with their babies, as far as I can remember. I’m thinking about Emily (Alexis Bledel) and Janine (Madeline Brewer) specifically. Who could have had a baby smuggled out of Gilead at the beginning of the takeover? I have a hunch that The Testaments won’t be able to resist a twist, so let’s all keep our eyes peeled for clues.
