I too believe she did something about the grimm maybe even turn the balance at the Great War.

Okay I may shock people here. Ozpin is using Ruby, he doesn't want to protect her. He needs her as his trump card in case of a new grimm war or maybe even use her against Cinder.

Ozpin is great but shows absolutely no emotions. Something happened to him that made him erect walls around his feelings, Summer perhaps?
