Selena

Selena is the daughter of a witch. She was hunted by the witch-hunter Agent Jackman and was placed in a safehouse. Agent Jackman then tricked the Charmed Ones into believing that she is a descendant to witch-hunters and took her right to him.

He attempted to burn her alive, but the sisters find out about his scheme and managed to save her.

Trivia
Though she is not a witch herself, she has the blood within her.
