The new season of Orphan Black has brought things back to basics — or as much as the series can after four years of relentless sci-fi twists. With Sarah Manning (Tatiana Maslany) on a desperate hunt for answers about herself and her clone sisters (also Maslany), the stakes just keep getting higher.

In this exclusive clip from Orphan Black's Thursday, May 5, episode ("From Instinct to Rational Control"), clone Alison tasks Sarah's foster brother Felix (Jordan Gavaris) and her own husband, Donnie (Kristian Bruun), to gather intel from a fertility clinic that may have ties to Neolution, the scientific movement that inspired the initial creation of the clones. In order to do so, Donnie and Felix have to pose as a couple.

In this clip, Donnie gets so into his character that he slips into gay stereotypes, putting on a slight lisp, waving his hand at the receptionist in a floppy manner, and calling Felix an exaggerated "darling." Felix, who is gay outside of this pretend scenario, isn't amused.

Never one to stay silent, Felix tells Donnie why acting like some clichéd gay man isn't accurate to life, saying that "science's commonly held belief is that 5 to 10 percent of your male friends are gay."

And Felix is ready when Donnie protests: "The point is you can't tell, so don't 'act' gay."

Donnie and Felix haven't had much of a chance to interact on Orphan Black up to this point, but if this clip is any indication, their next adventure will be, at the very least, an educational one.

Orphan Black airs Thursdays at 10 pm on BBC America.
