Previously — In episode 13, we learn the backstory of John Spillers, as told by Sergeant Zayas during his final moments following the attack on the Grass Cutting Area. Spillers was an immigrant from Holland who joined the crew of the Santa Maria as a cooper, and was later left behind in Haiti with 39 other men in 1492. He’s not only managed to survive 450 years, he’s doing whatever he wants. With impunity. First, there’s JTF Alpha—soldiers he’s hand-selected and modified with super-human capabilities. They can travel undetected, somehow under the concealment of a strange blue light. They also have astounding durability—one man took a face full of 30 caliber rounds from a Browning machine gun shortly before throwing a man into a wall from across a room like a lawn dart. We also learn that Spillers likely had cagey motives from the get-go with respect to the construction of the Grass Cutting Area—this is the top secret detention facility nestled in the jungles of Ramey Air Force base. After JTF Alpha parachutes in and kills everyone, it starts looking more and more like the whole place was intended to serve a single-purpose in a larger scheme involving the jibaro Jesus Santiago. And though it’s not clear why, Spillers still needs Santiago—alive.

Previously — In episode 12, Vandyck reveals her misgivings about Area J operator procedures — specifically, the over reliance on aperture screen technology. She mockingly compares this to Santiago’s no-frills demonstration from earlier, when he took control of a recorded session to directly address a room full of operators from his stone dungeon in Puerto Rico. Privately, she admires the old man, and wonders if she might be able to duplicate his results — essentially creating a bridge between her world and his.

Back at the Grass Cutting Area, there’s a catastrophic descent into chaos shortly after machine gun fire erupts. Communications have been cut off. JTF Alpha is inside the wire. In the confusion, the men of building two rush to the armory to gear up for a fire fight. Meanwhile, Captain Sepulveda takes a two-man detail to collect Santiago from his detainment cell, but when they hear the explosions and gunfire above, they realize building two is lost. The captain leads the group to cell number 3, locks the door, and orders his men to leave through the secret evacuation hatch built into the floor. When they’re safely gone, he draws and uncocks his sidearm, prepared to join his men upstairs. Santiago prevents him from leaving, tell him he’ll die if he walks out that door. They argue a while, but when Dawkins shows up, wiping his bloodied hands along the walls of the hallway outside and loudly boasting of his kills, Sepulveda realizes everyone he cares about is dead. Moments later, just as Dawkins kicks the door in, the air of the room folds over on itself. And Sepulveda and Santiago vanish in a pinwheel of blue sparks.
