She was involved with both of the murders that happened before Halloween. The first victim, she babysat their kid, and planted a hex bag. The second victim was at a party that Tracy was attending and she planted a hex bag in the sofa. Sam and Dean interview on what happened. They do get suspicious of her though and begin to investigate her.

When she is about to become the third victim, Sam and Dean save her, only to find out that she is a witch. She reveals to them that Don was her brother and how she wanted to kill him. So she completes the ritual with her brother as the thrid victim. Samhain rises and she greets him with open arms. As she goes for a kiss, Samhain snaps her neck and calls her "Whore".
