HBO/Sky Atlantic's The Undoing [1] is basically one twist after another. In the premiere episode of the six-part miniseries [2], Elena Alves ( [3]Matilda De Angelis [4]) is brutally murdered, and now it looks like Jonathan Fraser (Hugh Grant [5]) may be responsible for her death. Not only that, but he also might be the father of her newborn baby.
If you've read Jean Hanff Korelitz's You Should Have Known, the novel on which the show is based, then you already know that Jonathan turns out to be the father of Elena's younger son. It's unclear if series creator David E. Kelley decided to stick to the same storyline for the show, but judging from the latest episode, it's certainly looking that way.
In the second episode, we find out that Jonathan was secretly having an affair with Elena prior to her death, and Elena's husband, Fernando Alves (Ismael Cruz Córdova), has demanded a paternity test, insisting to police that he's not the father of Elena's baby. Shortly after, we see Grace Fraser (Nicole Kidman [7]) having visions of Jonathan and Elena having sex, which could be Kelley's way of subtly confirming that Jonathan is indeed the father, or it could simply be for artistic purposes. The news of Jonathan and Elena's affair explains why Elena was particularly taken by Grace when they first met, however, we're still left wondering about the paternity of Elena's baby. With four episodes left, hopefully we'll get some answers soon!
