Nick Burkhardt:
So, if one parent is a Wesen, and the other one isn't, what would the child be?

Rosalee Calvert:
You mean a Wesen and a Kehrseite?

Hank Griffin:
Yeah...

Monroe:
So, I guess it's time for the "Birds and the whole Bienen-Wesen" talk. Okay. If both parents are Wesen, then the child will be, too.

Rosalee Calvert:
Or if one parent is Wesen and the other is Kehrseite, then there's a 50-50 chance that the child will be Wesen.

Monroe:
Unless the Kehrseite is a Kehrseite-Gentrager. Then you're definitely getting a Wesen.

Hank Griffin:
Let's pretend I understood what you just said. What if both parents are Wesen, but different kinds?

Rosalee Calvert:
You mean like a Grudverschiedene situation, like us [Gestures to her and Monroe] ?

Nick Burkhardt:
Well, we don't mean to pry.

Hank Griffin:
Yeah, we do.

Monroe:
Well, then you're looking at a Vorherrscher. But, as long as it's healthy, we don't care.
