Very true :D

Im mainly basing it off the fact that Blake wasn't wearing one during the Black trailer, its somewhat un-justified but we'll find out soon enough.

Also, from the fact that Blake dosen't seem inclined to talk about the dark guy who started it, seems to lead me to think its Adam, merely speculation of course :)

And i just thought of something, Sun seemed quite surprised that the white fang were wearing Grimm masks, even though he seemed to be familiar with their activites and probably seen them in action (on news or otherwise) before concluding that the WF were jerks.
