Hayden Foster was a 16-year-old girl who lived with her mother and brother, Ben, in Wisconsin. Hayden was also in a secret relationship with an older man named Justin, who unbeknownst to her was a werewolf who wished to turn her and start a new pack.
Exiting a bar, Hayden is surprised by her brother, Ben, who was able to trick and bust her at the bar. While walking home down a dirt road, Hayden attempts to get her brother to go back to the bar with her, but he refuses. When they hear a noise from the woods, Ben goes to check it out. While he is gone, Hayden turns around and sends a text saying she's going back to the bar. When Ben emerges from the brush, he hears Hayden scream and rushes to find her laying on the ground. As he checks on his sister, a growl comes from behind him. He turns and sees a figure in black who lunges forward and stabs him in the stomach, killing him.
When Sam, Dean, and Mick Davies get wind of a possible werewolf attack they head to Wisconsin, where at a hospital the Winchesters interview Hayden's mother while Mick, disguised as a doctor, inspects Hayden's wounds. He finds a deep bite mark on her arm, but lies to Sam and Dean about it. Later that night, as Hayden is sleeping, her mother leaves the room and walks down the hallway. As she leaves, Mick enters. He stands by her bed and pulls a large syringe of silver nitrate out of his coat pocket. As he injects the syringe into Hayden's IV line, the clouds clear and the moon shines in the window. Hayden's eyes pop open and turn yellow. Her nails grow into long, black points. She attacks Mick, shrieking and growling. He turns quickly and plunges the syringe into her chest. She falls to the floor with the syringe still stuck in her. Her eyes turn back to brown and she stops breathing. As Mick leaves the room clutching his clawed shoulder, Hayden's mother and some nurses enter her room to find her dead on the floor.
