Changes

Sergei is a Russian [[shaman]] who used to consult for the [[British Men of Letters]] when they would come across an unsolvable problem. Sergei prefers not to have roots, claiming to have crossed the globe many times over to study and observe the skills of myriad witches, seers, and holy men. As a shaman, Sergei tries to "answer the unanswerable" and "know the unknowable" but considers himself first and foremost a healer. Despite seeing himself as a healer, Sergei works exclusively for barter, and has employed unsavory tactics in an attempt to acquire certain artifacts for his own unstated ends.

Arriving in a wooded area, Castiel begins walking to a trailer only to be stopped by a ring of [[holy fire]]. Sergei steps outside, shotgun in hand, and asks if Castiel brought anyone else with him. Once he is sure Castiel is alone, he invites him inside for some tea. Sergei give Castiel his "curriculum vitae", explaining his qualifications before moving onto the subject of Jack. He tells Castiel he does not believe Jack's condition can be reversed, but his system can be shocked to stop the progression. When Castiel asks how they could possibly achieve that, Sergei produces a vial of [[archangel]] [[grace]] which he says is from [[Gabriel]], explaining that he bartered a potent cloaking spell which allowed Gabriel to hide away in Monte Carlo for it. Handing it over to Castiel, he tells him they will need to recite a specific spell, then hands him the box which contains it. Castiel questions what the cost would be, but Sergei tells him his services are for barter only, and to tell the Winchesters that they "owe [him]."
