A few more details have trickled out concerning the introduction of Isis in the final season of The CW's Smallville. It turns out she isn't the DC Comics character -- Adrianna Tomaz, introduced in 2006's 52 -- but rather "the Egyptian goddess Isis with a nod to the DC Isis."

That information comes from Entertainment Weekly's Michael Ausiello, who learns from Smallville executive producer Brian Peterson just how actress Erica Durance will end up playing both Lois Lane and Isis.

"It’s an inhabitation story," Peterson says. "Lois is actually going to be possessed by the spirit of Isis." In other words, it's pretty much what you'd expect, probably having something to do with that necklace, which bears an uncanny (and certainly not accidental) resemblance to the mystical amulet from the 1970s Isis television series.

The "Isis" episode is scheduled to air on Oct. 22. The 10th season of Smallville debuts on Sept. 24.
