Watched "Nobody Knows the Trubel I've Seen" from Grimm. First appearance of Trubel (Theresa Rubel), a young, female Grimm who's been seeing Wesen and thinking that she's going crazy. In this episode she kills two male Wesen who try to attack her and a female Wesen on a separate occasion. Nick and Hank take her to Aunt Marie's trailer, where she is shown the books. Nick explains to her what a Grimm is and takes her home to Juliette to have dinner with them.

Adelind desperately seeks help from Nick and Juliette, from Monroe and Rosalee, from Captain Renard, and from Viktor, whom she calls from Portland.

One of Viktor's men remains in Portland to assassinate Captain Renard.

From what I remember of my TV viewing, Trubel was quite an unforgettable character.
