After playing the game "Stay Alive" (spearheaded by a villainess named the Blood Countess), Miller and Phineus (Adam Goldberg and Jimmi Simpson) die the same way they die in the game.
October (Sophia Bush) is killed by the Blood Countess when the game unpauses and plays itself. Hutch, Abigail, and Swink (Jon Foster, Samaire Armstrong, and Frankie Muniz) find the Blood Countess' tower (where she was walled up) and dispose of her body through a ritual in the Malleus Maleficarum (Witches' Hammer) and burn down the tower.
At the end, "Stay Alive" is released in stores and reveals the Blood Countess is still alive.
