These are some truly story-and character inconsistent statements. In one of the first episodes (the pilot?) Nick spent all night reading true the books, while Juliette stood in the bedroom window looking down on the trailer. When Nick ENTUSIASTIC told Juliette about the trailer, books, films, weapons, and potions, he seemed to know it all:
Nick: “See these books? They're filled with drawings made by my ancestors and some other people who had the same ability. And the drawings are of Wesen, which is how they like to refer to themselves. […] No, the Wesen. And that's what I can see. What the Grimms could see. And there are all kinds of them. They're kind of like species that exist within us-- some of us. Anyway, there's Blutbad and Bauerschwein, Fuchsbaus, Eisbibers. Remember that fire dancer Ariel? […] She was a daemonfeuer. A dragon thing. And they're all in these books. Look. Lowen are a kind of lion. Look at the picture here. Juliette, I mean, I'm not making this up. I mean these lowen were running an illegal fight ring that dates back to the time of the gladiators. They were fighting with these. Ancient weapons. This is a morning star. There's a rifle in here that shoots special bullets to kill Siegbarstes. But first, you have to dip them in this stuff here. This stuff right here. Siegbarste gift. Gift means poison in German. The point is I can see these Wesen in what you would see as a perfectly normal person. When they go through something called the woge, which is kind of like this emotional surge, that's when I can see them. I know how this must sound, but I swear to God, it's all true. Look, you want to see who Adalind really is? This is what Adalind really is, a hexenbiest. Juliette, you got to read some of this stuff. I mean, the stuff's that's in English because most of it's in German. And there's actually some of it in French, Spanish, and even Latin. Oh, there's some of it in Japanese. They all look like stories you'd read in a book, but they're not. They're real. [...] Ah... Cameras. And film of Hitler and the Verrat shooting people in 1936. The Verrat worked with the seven royal families, which I'm just beginning to learn about. Juliette, I can't tell you how it all fits together. Even my parents were killed because of this. My aunt was a Grimm all these years. I didn't even know it. Look. I can show you film right here that will blow your mind. There are things in this trailer that you can't believe”. Does not sound like someone who have no interest in learning about his family-history or reading Grimm books.
Wu spent ONE NIGHT reading some books (and eating fast-food). Unlike Wu and Truble, who only spent a little time in the trailer, Nick visited the trailer regularly for 4 seasons. We also know Nick spent a lot of time in the trailer between episodes, both based on things he told Monroe and because the weapons in the cabinet was reorganized between episodes. Obviously Nick spent a lot of time learning. When? We never saw Nick going to the hairdresser or using the toilet either, but I am sure he did.
