Juniper 2

I Looked on the IMDb website and looked at the cast for the movie and found out that they are putting Juniper (Grover's Girlfriend) in the movie and she doesn't get introduced until the 4th book this is what Im talking about mixing up the books with the movie they are probobly trying to put as much of the other books as they can because they are afraid that they will not get to all of the movies
