Katherine Ramdeen is a Canadian actress who portrayed Alex Jones in Season 9, Season 11, Season 12 and Season 13 of Supernatural. She would have had a main role in the upcoming Supernatural spin-off, Supernatural: Wayward Sisters if it had gotten picked up.
She has also appeared in The Tall Man.
Ramdeen commented in an interview: "I'm a fan of Star Trek, and watching Deep Space Nine is a different story because they're on a space station, and they're stuck in one place. But the thing is when we're all in Sioux Falls, presumably, that just means that we can just go so much more in depth with the relationships that we have between the women... but that being said, I think there's definitely a mechanism in place that's going to make Sioux Falls a place a hunter would want to be".
