Pamela Barnes

Pamela Barnes is a Psychic who helped Dean and Sam Winchester discover what pulled him out of Hell in Lazarus Rising. While doing this, the angel, Castiel, warns her not to go any further. Nonetheless, she does and as a result looses her sight. Because of this, she wears plastic balls to replace her eye sockets and wears shades. She has a strong sexual attraction to Sam Winchester.

In I Know What You Did Last Summer, Pamela returns to help discover who Anna Milton's "Father" is. She uses hypnosis and helps Anna realize she is a fallen angel.

Pamela returns to help the Winchesters in Death Takes a Holiday. They need her to cast Astral Projection and send them into the Spirit World, so the brothers would know who's kidnapping the reapers. Once the demons discover the brother's motive, they try to kill Pamela. However, before they do, she snaps Sam out of the Spirit World. Sam is able to extract the demon, but not before Pamela gets stabbed, fatally wounding her. With her final breath, she mentions to Sam that she knows what he's doing.
