Well, that was very interesting; totally different from my expectations (which is always a good thing).

So, what did we learn?

1) The girls are currently in an old 'The Last of Us' set;

2) A lot about the girls - Weiss is motivated by a sense of duty; Yang is an adrenaline junkie with a social conscience; Blake wants to solve the world's problems (but does not know how);

3) Oobleck is honestly guided by a desire that no-one else should die;

4) Ruby is either incredibly lucky or is some kind of savant about what a Huntress needs. Dr Oobleck actually thinks Zwei will potentially be useful;

5) A new Grimm species - Goliaths are elephant Grimm;

6) Grimm grow more intelligent as they get older and generally avoid attacking humans. When they reach the highest level, they just wait patiently, presumably for their time to come;

7) Grimm are drawn by human negative emotions such as fear, greed and hate. The presence of so many Grimm possibly means a bad guy base is nearby;

8) The girls can handle lv.2 Beowolves and lv.1 Nevermores by the dozen without breaking a sweat.

Okay, so now a prediction:

The Grimm are drawn to negative emotions, so a White Fang base is hidden in the ruins of the ruined city. More importantly, the Goliaths' presence means that they are instinctively aware that darkness is rising inside Vale; they are drawn to it and are now just waiting until it grows so strong that it snuffs out the light protecting the city and the way is opened for them to destroy those behind the walls.

If, as I suspected, Cinder's virus knocks out the city's communications and defences, then there could be armies of Grimm out there, ready to come storming in and destroy everything.
