Changes

Tracking the owner of the car, Sam and Dean find Garth in an apartment. A woman [[werewolf]] -- [[Bess Myers]] attacks them, and Garth reveals that not only is she his wife, but he is a werewolf as well! Garth describes how he was bitten by a werewolf while on a hunt six months previously. He was going to kill himself when Bess found him. She took him into her pack, which is led by her father. Bess herself was born a werewolf. Garth tells the Winchesters that the pack only eats animal organs, and doesn't attack humans. Dean in particular is doubtful, but agrees to visit the pack and see for himself.

Dean is greeted by Bess' stepmother, [[Joy Myers]] at a house where he finds Garth playing piano for the pack, which is singing a Christian hymn, led by Garth. Over a lunch of raw meat (although Dean gets cooked steak and pie), the [[Reverend Jim Myers]] explains that they are peaceful. Dean notices they all where wear a [[silver]] bullet around their neck, and Bess says its to remind them of their vulnerability. After lunch Kevin , Garth is upset that Dean is still skeptical as to the packs benign ways, and is also saddened to hear about [[Kevin]]'s death.

Sam meanwhile visits the local sheriff, [[Sheriff Pat|Pat]], who assures him that the Reverendmembers of the revererend's congregation are pillars of the community. That night he calls Sam and dean Dean to the site of a deer slaying. However, it is a ruse and Russ, who is a werewolf, attacks them and in the fight is killed. On examining the body, Sam and Dean find him wearing a bullet with "[[Ragnarök]]" inscribed on it. Dean remembers that this is part of the apocalyptic legends of Norse mythology.

Sam goes to Garth's apartment, and find signs of a struggle, and calls Dean to tell him Bess and Garth are missing. Sam is then overpowered and taken captive.

At the pack's church, Dean finds a book about Ragnarök, but reverend Jim arrives to explain that it while it was linked to a cult called [[the Maw of Fenris]] that believed in werewolf domination over humanity, his pack no longer subscribed to these beliefs. When Dean tells him about Russ' attack and the inscribed bullet, and that Garth and Bess are missing, the Reverend realizes who may be behind it.

Sam wakes up in a barn Garth and Bess are held by Joy, [[Russ]] , and [[Joba]]. Joy reveals that they are part of the the Maw of Fenris, a cult dedicated to bringing about Ragnarök. Joy plans to murder Garth and Bess and frame Sam and Dean to turn the pack against humanity. Garth unsuccessfully pleads for Bess' life and struggles against his restraints to no avail. However, at the last minute, Dean breaks in, having killed after killing Russ and kills Joba and Joy.
