Marcy Ward is Bobby Singer's neighbor who had a crush on him.
She first appears when she introduces herself to Bobby bringing a peach cobbler. At his door she attempts to invite him over to her house, but he turns it down. She hears screams in the house, and Bobby tells her that its a scary movie. So she leaves.
She later gets attacked by an Ōkami, and Bobby saves her. She watches Bobby fight the creature, and eventually puts it through the wood chipper she told Bobby was broken; which wasn't. As the creature goes through, she gets sprayed with the blood. When Bobby asks about the wood chipper she admits it was to get him over here. When Bobby says he could pop by, Marcy tells him it's not going to work out.
