Changes

Sergei arrives at [[the Bunker]], in awe of being in the fabled home of the [[Men of Letters]]. Castiel leads Sergei to the infirmary, where [[Eileen]] is tending to a still-unconscious Sam, and pleads for him to help Sam. Sergei obliges, producing a crystal from his satchel and waves waving it over Sam's body until it begins to light up when he it reaches Sam's bullet wound, and . He instantly realizes what it wrong -- Sam is dying.

In the Bunker library, Sergei explains that Sam's wound is connected to his [[soul]], as well as and also tethered to someone or something in the outside world. After treating Sam's wound, Sam's condition becomes worse. Sergei tells Castiel and Eileen that in exchange for finding the [[Key to Death]] in the Bunker, he will reverse what he has done to Sam. Eileen and Castiel refuse, and Castiel shows Sergei a photo of his niece, whom he has [[Bobby Singer (Apocalypse World)|Bobby Singer]] keeping an eye on, and threatens to have her harmed if Sergei doesn't fix Sam. Sergei agrees and performs a ritual that wakes Sam up. Upon leaving, Sergei remarks that he likes the new Castiel, telling him it he is very... Russian.
