Here’s a fun bit of casting quietly nestled at the bottom of ABC’s press release for the next episode of Once Upon a Time: genre-TV fave Jaime Murray will be guest-starring.

In the ninth episode of Season 6, titled “Changelings” (and looking very ominous for Rumple and Belle), the Brit beauty will be playing the Black Fairy, TVLine has confirmed. (Her first name was spelled “Jamie” in an early version of the release, conjuring a bit of confusion.)

Murray most recently played the milky-complexioned alien Stahma Tarr on Syfy’s Defiance. Her other previous TV credits include Warehouse 13, Ringer, Spartacus: Gods of the Arena and Dexter.

Once Upon a Time is off this coming Sunday, due to ABC’s broadcast of the American Music Awards; “Changelings” will air Nov. 27.
