Warning: This article contains FULL SPOILERS for the ending of the series. Midnight Mass is currently available to stream on Netflix.
Now that you've (hopefully!) made your way through all of Mike Flanagan's Midnight Mass, let's unpack the final episode -- "Book VII: Revelation" -- and the series' ending as a whole to see where the story landed.
And if you haven't yet, feel free to check out IGN's Midnight Mass review here!
The penultimate chapter, "Book VI: Act of The Apostles," capped things off with a harrowing Easter service bloodbath, as Monsignor Pruitt (Hamish Linklater) introduced the "Angel" to his congregation, encouraging everyone to take poison so that they may be resurrected in eternal life - aka as vampires (though vampirism is never said outright).
While this truly horrific scene occurs, with families watching each other painfully die and come back to life, Mildred (Alex Essoe) shoots Pruitt "dead," allowing Bev (Samantha Sloyan) her chance to take the reins on this awful operation. A few escape the massacre un-vampired, but Bev then orders Sturge (Matt Biedel) to open the doors, damning the rest of the residents of Crockett Island to the cravings of the St. Patrick's horde.
Pruitt, coming back to life, weakly objects, knowing this wasn't the plan, but Bev is unstoppable now. "Let God sort them out," she cruelly says, knowing that those left on the aisle who weren't attending church and taking communion wouldn't get resurrected.
For creator/writer/director Mike Flanagan, the thematic ties between religion and vampire lore have fascinated him for a long while. In an interview with IGN, he spoke about his preoccupation with "what happens when we die."
"Somewhere around 2008 or 2009, the idea of vampire blood being in communion wine took root for me and how -- if people experienced the benefits of vampire blood that I'm familiar with from their expressions in the genre -- that they would believe them to be miraculous. I thought that that was just a really irresistible idea."
"Being that weirdo, who was already a burgeoning horror fan, who looked around when they said this is the blood of Christ and if you drink it you'll live forever. Looked around and said, 'Does anyone else think this Vampiric?' And being told by parents and teachers to please stop bringing that up."
Let God Sort Them Out
The finale, "Book VII: Revelation," tracks the newly-christened vampires, released from St. Patrick's as they devour the stragglers, the dozens still left out on the island, while Erin, Sheriff Hassan, Sarah, Warren, Leeza, and Annie do their best to survive (and sabotage Bev's plans to spread this "gospel" to the mainland by burning the boats).
With a bloodlust that all but Ed (Henry Thomas) find too irresistible to manage, the vampires ransack the island, killing the rest of the citizens, most of whom perished in the carnage. After Warren (Igby Rigney) and Leeza (Annarah Cymone) discover the Angel feeding on a poor woman -- in a type of feeding trance that consumes all of its attention -- they try to light it on fire. When Bev sees the house burning, she decides that the entire island can burn, as long as the church and the recreation center stand as shelters for them during the daylight hours.
Monsignor Pruitt, Mildred, and Sarah
Mildred, having been attacked directly by the Angel, wakes up as a vampire, in the form of her "best self," a much younger version (like Pruitt), and finding Pruitt inside the church. It's here that he confesses his real motivations for bringing the Angel to the island. The heart of his plan was to share this "gift" with Mildred so that the two of them could have a second chance to be together, and then even reveal to Sarah that he was her real father.
Though it was his plan to (kill and) resurrect this island on Easter, a scheme born of his love for Mildred ("even out of blackness, love rises again"), it wasn't his idea to unleash his congregation on people who couldn't be brought back to life. He wanted the church doors closed and locked for when they all woke up so that he could explain to them what had happened, much like he had done with Riley. But now Bev had taken over and Pruitt was defeated. While the island burned, he chose to spend time with Mildred.
In the climax of the episode, Pruitt, disgusted by Bev and what his congregation had become, found Sarah (Annabeth Gish) inside St. Patrick's spreading gasoline around. Realizing his daughter -- to whom he'd never gotten to tell the truth -- was doing the right thing, he told her to escape out the back. But right then, Sarah was gunned down by Sturge. Dying in her parents' arms, Pruitt attempted to feed her his blood so that she could be brought back to life. But Sarah, with the strength she had left, spit out the blood, refusing to become a vampire. In the end, Pruitt and Mildred carried Sarah's body to her favorite bridge and waited for the sun to rise.
