The actress will portray Amelia, a doctor with a "damaged soul" who becomes romantically involved with Sam Winchester (Jared Padalecki). The character is still trying to overcome a traumatic experience, although we eventually learn she is, "brave, sweet and sarcastic." It isn't known when the actress will make her debut in Season 8, or how many episodes she is slated to appear in.
We reported last month that the Season 8 Premiere will debut Wednesday, October 3 at 9 PM ET. Last season, the show aired Friday nights at 9 PM.
Supernatural will also be heading to Comic-Con 2012 this week, so stay tuned for updates on the upcoming season from San Diego.
