Season 9
Joy in werewolf form
As her husband preached, she tried to co-exist with humans. But last year, her brother Charlie, was killed by a hunter. She decided that as long as man lived, he would only destroy. So she decided to bring on the werewolf apocalypse, Ragnarok. She revealed that they are part of the The Maw of Fenris, a cult dedicated to bringing about Ragnarok. Joy planned to murder Garth and Bess and pin them on Sam and Dean to turn the pack against humanity. Garth unsuccessfully pleads for Bess' life and struggles against his bonds to no avail. However, at the last minute, Dean broke in and killed Jobah, having already killed Russ. Joy went for her gun which had been knocked out of her hand by Sam while Dean went for his. Dean was faster and shot Joy dead.
