Not all that much has actually happened, but there are 28 different accounts of a fairly short story posted to the IC.

Basically Geni let slip he was once with the White Fang. Ivan being the ass he is got angry, Geni started a fight. A bunch of people picked sides but Amy and Sapphire managed to stop it before any lasting damage could be done. Geni ashamed of almost attacking another student ran from the room. Sapphire followed but before she could sort out what was going on with him the teacher showed up to have words with Geni, he ordered Sapphire back to class. She pretended to follow orders but snuck back with her unnoticeable semblance active in order to eavesdrop. Now we're just waiting on the teacher to start reprimanding Geni.

I haven't been reading what's going down in Grimm Studies cause well, I got enough to go through in the Armoury class and Sapphire wouldn't know about anything in GS anyways.
