As if hospitals aren’t scary enough as it is, things are getting even more unsettling for the staff of NBC’s hit medical drama Brilliant Minds as spooky season checks in with a Halloween episode. And that is saying a lot for a show that regularly freaks us out with cases like face blindness, alien-hand syndrome, and mirror-touch synesthesia.

“Wait until Monday’s episode. We get weirder,” warns showrunner Michael Grassi with a laugh. “Bronx General is a very lively place on Halloween, as you can imagine.” He adds that we should expect to see some of the staff trading their lab coats for Spirit Halloween-wear. “There are costumes in this episode, and there’s one couple’s costume in particular that I think is really special ,” he teases. “I cannot wait for audiences to see it.”
