Hank the police office in the first season didn't know about wesen, but was now dealing in wesen cases. We know that Nick once said that Hank would not have seen the things he did if he didn't have Nick as a partner (S2E3). I've been rewatching season 1 and IMO NIck was correct in saying that.
The case they worked in season one had Nick not been a Grimm would have been treated differently. Now would these case have been solved if Nick didn't have Monroe or the books? Take the bat girl case, how would a regular police officer had figured that case out?
Now after Nick becomes a Grimm he now see thing in a new light giving him information not known in the past. So the question one would season one cases have been solved if Nick wasn't a Grimm if so how? Question 2 was Nick's new understanding of the world the reason that Hank needed to know the wesen world? We seen what not knowing cost Hank and later Wu so think about these cases that Nick was now solving.
