1x05 Bloody Mary

When a man is killed—his eyeballs having exploded—after his daughter chants "Bloody Mary" three times in front of a mirror, Sam and Dean head to Toledo, Ohio, to investigate. They learn that Bloody Mary (Jovanna Huguet) is the ghost of a young woman who was murdered after her eyes were cut out, and her spirit trapped within the mirror that she died in front of. With the mirror now for sale in an antique store in the town, Bloody Mary has begun to target those nearby who secretly feel guilt over another's death. The brothers must find a way to stop her after a young girl (Marnette Patterson) inadvertently becomes her next target. They track down the original mirror and then smash it, but this only releases Bloody Mary. However, Dean forces her to see her own reflection, and her guilt over her own secrets causes her to vanish.
