In the trailers and the episodes, the Grimm can be seen reacting to events (Beowolves reacting to the Crescent Rose) and actions (The Ursa's reaction to Yang's rage mode) implying that they are not just dumb drone-like monsters, but have a degree of intelligence. Enough to have meaningful reactions to their enviroment.

My question is, too what extend do you guys think their intelligence goes?
