Much of what I've heard deals with Huntsman culture, I suppose? He's told me about his preferred types of missions and what others tend to exist, about the Grimm and their... properties... [He guesses that's the best way to put it considering they are just very weird.] ...how some Huntsmen will belong to one city or village and others roam.

[In other words, he's shared things related to him without quite getting too deep into anything painful.

But he does remember another thing.]

Ah! He told me about emblems. Those... seals you all have apparently? He showed me his. He thought it would be nice if I made one someday, which was why he had to explain them to me.
