So yay, more stuff to comment on.

First off, it turns out that Velvet is actually an upperclassman, and has lines now. So she isn't a freshman like everyone apparently thought. Weiss is a dog person, Blake is not (surprise surprise), and Tai Long is kind of a jerk for sending a dog and two weeks of food in the mail. And that dog is totally stuffed into Ruby's backpack, just saying. 

More character development, Ironwood is a very direct, blunt kind of guy. Pre emptive strike with overwhelming force, end the threat before it begins. Also, history. Color based names come from some conflict that may or may not be related to the Human-Faunus War, though you wonder how they managed to fight these conflicts with the Grimm so prevalent beyond the walls of the kingdoms and the geographical distances involved. But I suppose things were different then. It might be that that war was what shattered the Moon. 

Moreon, nice guy Ozpin, also genre savvy, and realizes that it's better to officially endorse RWBY's presence on the mission rather than having them sneak behind his back. Of course, considering who they ended up with, this can only end well next episode.
