Warning: This post contains spoilers for Something Very Bad Is Going to Happen.At first it seems like one type of very bad thing is going to happen. Then it's another. By the finale of Something Very Bad Is Going to Happen, the very bad thing that's about to happen has become all too clear. But that doesn't mean our doomed protagonists are capable of stopping it.Created by showrunner Haley Z. Boston (who previously wrote for Guillermo del Toro’s Cabinet of Curiosities and Brand New Cherry Flavor) and executive produced by the Duffer Brothers (Stranger Things), the new Netflix horror series, all eight episodes of which are now streaming, spans the week leading up to the ill-fated wedding of engaged couple Rachel Harkin (Camila Morrone) and Nicky Cunningham (Adam DiMarco). After a disturbingly eventful drive out to the Cunninghams' remote cabin compound, Rachel originally comes to believe her fiancé's family—who she is meeting for the first time—is planning to sacrifice her in some sort of satanic ritual. But after the Cunninghams' strange behavior is mostly explained away by the revelation that Nicky's mother, Victoria (Jennifer Jason Leigh), has a terminal brain tumor they've been keeping secret from Nicky, Rachel is forced to contend with the real supernatural danger hanging over her head."The first half of the show, Rachel believes the threat is external. Then by the midpoint, she realizes it's coming from within," Boston says of the initial bait-and-switch. "She thinks this family is out to get her, that there's some evil in the woods. Then she realizes it's actually her. It's her doubt that's causing all this anxiety. There's something interesting about wanting to put the blame on other people but ultimately realizing you have to go deeper inside yourself in order to face your fears."An irreversible curse(L-R): Adam DiMarco as Nicky and Camila Morrone as Rachel in Episode 5 of Something Very Bad Is Going To Happen. —NetflixAs it turns out, the Harkin family has been damned by a curse that causes any member of the bloodline who marries someone who isn't truly their soulmate to gruesomely bleed out and die once the sun sets on their wedding day. Rachel ends up learning this information from the creepy old man (played by Zlatko Burić) she first encountered peering down at her in a bar bathroom on the drive out to the cabin. The man, who we'll refer to as the Witness from here on out, reveals the curse was passed on to Rachel's family as a result of his long-ago decision to jilt his bride-to-be at the altar. He tells Rachel the curse originated from a bargain his great-great-great grandmother made with Death itself to bring her deceased fiancé back from the dead. Death agreed, so long as she believed her late groom was truly her soulmate. Then, for good measure, Death also cursed all her children, her children's children, and so on to carry the same burden. After the Witness got cold feet on his beloved Marianne, she eventually went on to marry a man named Thomas Harkin, Rachel's great-great-great-great-great-grandfather. Thus, the curse was passed to the Harkins and the Witness was punished with immortality for betraying Death's bargain. Since that fateful day, he has been forced to bear witness to all the weddings in Marianne's bloodline. As the Witness informs Rachel, it's simple. She must get married by sundown on her wedding day. If Nicky is her soulmate, she will live. If he's not, she will die. Considering Rachel has also just learned this is exactly how her heavily pregnant mother met her end on the day she married her father—prompting him to perform a forced C-section on her mother's lifeless body to keep baby Rachel alive—she already isn't feeling so great about the whole situation. "I believe there are right people and wrong people. I don't believe in the fated side of things," Boston says of her opinion on soulmates. "But when I was figuring out how to answer the question of what makes people soulmates, I didn't want it to seem like I had some holy answer. I think the right person will see you for who you truly are."A blood-soaked finaleRachel and Nicky's wedding gets underway in Episode 8 of Something Very Bad Is Going to Happen. —NetflixRachel's belief that Nicky is her soulmate is fueled by their couple origin story, which revolves around neither of them getting on a plane after being unable to shake the feeling that something bad was going to happen and instead choosing to make the four-day drive to their final destination together. So when it comes out at their rehearsal dinner that the circumstances of their airport meet-cute were all a lie, Rachel begins to have pretty serious doubts . By the time their wedding day rolls around, Rachel is prepared to undergo a painful and irreversible ritual to ensure she truly is Nicky's soulmate—even if it changes her into a different person entirely. But in the end, she decides to put her faith in her connection with Nicky and forge ahead with the ceremony as her true self.However, Nicky has spent this time stewing over their relationship as well and ultimately refuses to marry Rachel at the altar. He claims this is because he feels it's what she actually wants, but he eventually admits he also doesn't really believe in the curse. Unfortunately, Death's bargain is all too real. And when sundown arrives without a married couple to show for it, the burden is passed to Nicky's bloodline, causing all of his non-soulmate wedded relatives in attendance to begin hemorrhaging out. Nicky then tries to reverse the damage by slipping a ring onto Rachel's finger and saying "I do," completing the ceremony without her permission to force her into marriage. This, in turn, causes Rachel to bleed out and die."If Nicky had said yes at the altar, if he had just been even and if he hadn't grown at all, everything would have been fine," Boston says. "That's kind of the great tragedy of the finale. Ultimately, the show is saying that the greatest sin is not believing your person is the right person for you."The next morning, Rachel awakens once more, having been brought back to life as the new immortal Witness who will now be required to attend every wedding involving a member of the Cunningham bloodline. The final sequence of Something Very Bad shows Rachel driving away from the cabin alone before faintly smiling to herself. "The whole story is a breakup story. So Rachel dying is the death of the relationship. It's the death of her old self. And in order to move on, she had to be reborn," Boston says. "When you exit a relationship, you leave all that behind and you're free, though not unscathed."
