Why does everyone think he is a Grimm. It's doesn't make sense for him to be a Grimm. All the evidance i've seen is pointing to him being a Wesen. Remember when he was talking to the Lowen guy. He said that back in the old days things were different. A hint that he is older then he appears to be. There is nothing that says Grimm's age slower and live longer than other humans.

Also just because Nick hasn't seen his Wesen face doesn't mean he isn't Wesen. In the episode Organ Grinder. Nick never saw the wesen face of the female docter until she turned and attacked him at the end of the episode
