Aubrey and R. arrived from groceries while I was watching "The Grimm who Stole Christmas" from Grimm. A package arrives at a Christmas party. Later that night, three goblins come out of the box and create havoc, tearing down all the Christmas decor. Nick and Hank respond to the report, and to yet another. They manage to catch one of the goblins and put it in a cage in Monroe's and Rosalee's house, but it escapes and proceeds to create havoc until Nick, Hank, and Monroe chase them away. They go to the trailer and learn that the goblins are Kallikentzaroi, children who morph into goblins during the puberty stage and usually within the 12 days of Christmas. They are highly attracted to sweet cakes and return to their normal shapes when the sun comes up. In a succeeding investigation the parents of one of the three boys inform Nick and Hank that the boys are performing in a Christmas choir in church that evening. Nick and Hank fill a closed truck with fruitcake. The boys morph into goblins and go inside the truck, where Monroe and Rosalee lock them until the sun comes up that morning.

Trubel, Josh, and Bud stalk Shaw's hideout and learn that Shaw and his mates are members of the Wesenrein, the association that advocates purity of Wesen and hunts down mixed-marriage Wesen to annihilate them.

Trubel and Josh travel to Pennsylvania because Josh now wishes to face the men who invaded his home, thinking that his father's key is there.

I have one question after all this, though: How did the three goblins get themselves inside a gift-wrapped box and have it delivered to a Christmas party?
