Elyse Levesque has booked a ticket to The Big Easy.

And this could mean trouble for Rebekah and Marcel.

The SGU Stargate Universe alum will recur on The CW smash as a witch named Genevieve, TV Line reports, someone who returns to her native New Orleans due to "unfinished business" with the aforementioned duo.

It's safe to assume this will have a lot to do with the secret Marcel and Rebekah shared to close out The Originals Season 1 Episode 9.

Levesque will debut on Episode 13 and stick around for a few weeks.

The Originals, meanwhile, closed out an excellent first half of Season 1 episodes this week and returns on Tuesday, January 14.
