This week on Grimm we learn a new way to spell “trouble,” as we meet Theresa Rubel. T. Rubel. Trubel, see? And she’s not a Wesen. She’s a Grimm. She just doesn’t know it. As you’ll see in the synopsis, screen cap pictures, clip, and TV spot below.

We also have, for your Grimm pleasure (because I cannot resist playing with the show’s title), two featurettes with guest star Jacqueline Toboni. Have at ’em:
