Well, it might sound like a weird question, but did the Series ever stated anything about the origins of Grimms? All the wesen names are (sorry to say that) really bad translated German words, either names of animals, or words to describe them. However "Grimm" is a family name. I recall the first season, telling some story that the Brothers Grimm were not just story tellers, but hunters. However, the history of Grimms in the series is much much older, than the Brothers Grimm. Therefore either they must have inherited the name from a long bloodline of Grimms, or there was another name for Grimms before the two famous brothers. Maybe I am the only one caring about such details, but one of the reasons I like the series so much is, because that's my own German bloodline there, and watching a series about it is kinda cool. Maybe some of you have better memory, or you guys spotted some details in the series, which I might haven't spotted yet.
