Watched "Star-Crossed" from Grimm. A Wesen ritual killer is crucifying and murdering six victims. Nick, Hank, Rosalee, and Monroe figure out that the locations correspond to the seven stars of the Big Dipper and superimpose the figure on a map. Nick, Hank, and Sergeant Wu go to the seventh location, shoot the Wesen, and save the seventh, prospective victim from being killed.

Meisner, Juliette, and Trubel continue their efforts to locate a Black Claw terrorist who is in Portland.

Interesting, but the mystery formula is too Name of the Rose.
