Meeting your future in-laws is never easy and on Friday’s episode of Grimm, Rosalee (Bree Turner) is going to learn this first hand.

In the exclusive sneak peek below, watch as Monroe’s (Silas Weir Mitchell) parents, played by Dee Wallace and Chris Mulkey, drop in on the couple for a visit, only to find a frazzled (and somewhat unprepared) Rosalee.

Grimm airs Fridays on NBC.
