S4E4 · Chloramphenicol

Complete story — includes the ending

With glanders lingering, Philip, Elizabeth and William quarantine in Gabriel's apartment for several days, worrying Paige. Elizabeth calls off the execution of Pastor Tim and Alice and begins to develop symptoms. Martha goes out to dinner with Agent Aderholt; to explain her movements after work she tells him that she is dating a married man. Agent Beeman searches her apartment during her absence but finds nothing incriminating. By the morning both Gabriel and Elizabeth have improved and William pronounces them out of danger. Elizabeth finds that she now agrees with Philip that they cannot kill Pastor Tim and Alice without alienating Paige. The Jenningses propose that they instead "work" the couple to ensure their secrecy. Oleg returns home to Russia and asks his influential father to assist Nina. His father agrees on the condition that, if he succeeds, Oleg will remain in Russia. In prison, Nina has another dream of being set free. A trio of guards wake her and lead her down a hallway, where she is informed that her appeal has been denied and that her death sentence will be carried out shortly. She begins to break down but is executed on the spot.
