Patience

Patience is a witch or possibly a whitelighter who works in Salem doing reenactments of the time of the Salem Witch Trials. She has the ability to refill a glass with water, an ability only seen by Leo in the first season or possibly similar to when Prue added the cream to the coffee in the pilot and the ability to move objects with her mind through telekinesis as she waved shut a door when Sarah left. She says she is older than she looks. She does imply that she, like Sarah, is a witch.

Where There's Smoke There's a Firestarter
Patience tries to help Sarah become comfortable with the fact that she is a witch. She doesn't liked being called "Ma'am" and finally gets Sarah to call her by her name. She also shows Sarah what she can do with magic refilling a glass of water.
