Charisma Carpenter is returning to The CW, in a familiarly formidable role.

TVLine has confirmed that the Veronica Mars alum and onetime Supernatural witch will guest-star in Pandora‘s Season 1 finale (airing Tuesday, Oct. 1) as Laura, a mysterious woman who might have all the answers to Jax’s questions about her origins… but who also might be Jax’s most dangerous enemy yet.

ComicBook.com first reported on this casting as well as Arrow alum Manu Bennett’s own Pandora role.

Carpenter’s other previous TV credits include but are no means limited to Buffy the Vampire Slayer and its offshoot Angel, The Lying Game, Greek, Veronica Mars, Chicago P.D. and Lucifer.
