|Episode(s)||8.07 A Little Slice of Kevin|
Delta was in a band and became a full witch after her band broke up.
In order to make "demon bombs," based on instructions from the demon tablet, Linda Tran hires Delta off of Craigslist in order to get all of the ingredients they need. She informs Delta of what they are trying to make, but not how to make them or the amount of ingredients needed for each. Delta gets the needed ingredients, but frustrated with the way Linda is treating her, she tells Crowley where to find Linda and her son the prophet Kevin. Delta brings some of the ingredients, enough for at least one bomb, but claims she won't bring anymore until she is paid. Upon arrival, Linda squirts her with holy water to prove that she is not possessed. Using an excuse, Delta gets Kevin, who is attracted to her, to let her go into the backroom where she breaks the salt line there so the demons can get in. Kevin discovers this when he goes to get his mother's purse and the demons arrive. Crowley, annoyed with Delta's attitude, snaps his fingers and sends her away somewhere.
