|Episode(s)||3.09 Malleus Maleficarum|
Funny story actually. You remember all those dark demonic forces you prayed to, when you swore your servitude? Just who did you think you were praying to? What did you think it was? Make believe? Positive thinking? The Secret? No, it was me. You sold yourself to me, you pig.
– Tammi Benton, 3.09 Malleus Maleficarum
Tammi Benton was a friend of Renee, Elizabeth, and Amanda Burns before she was possessed by a demon. The demon possessing Tammi uses her demonic powers to help Tammi's friends but it was later revealed that she was doing this to get the ladies' souls. She was the one who brought the spell book to book club and introduced them to witchcraft. She reveals that when Ruby was human, she was a witch who sold her soul to her.
She has motivated a group of women to dabble in witchcraft for what they think are simple gains, but in reality they have sold their souls to her. Though she manages to overpower Ruby, Dean, and Sam, when Elizabeth uses a spell to harm her, Dean is able to grab Ruby's knife and stabs her several times with it, killing her, though not before she kills Elizabeth for harming her.
- Though not named in the episode, the official companion for season 3 lists the name of the demon possessing Tammi as "Astaroth."
