Changes

When Sam calls Ketch to help find a way to save Jack, he Ketch tells them about [[Sergei]], a nomadic [[shaman]] that the British Men of Letters often consult with when they need to "solve the unsolvable." Ketch facilitates a meeting between Sergei and Castiel. Although Sergei has never met Ketch in person, he calls their reputations "mutually stellar." Sergei provides a spell that can save Jack and a vial of Gabriel's archangel grace, but Jack's condition worsens as a result. Sergei later reveals that it was an untested experiment and therefore Ketch's efforts are were fruitless.
