I agree that Ozpin's time to die has not yet come. An off-screen death for Port and Oobleck would be narratively appropriate.

However, I could see Glinda dying trying to protect Ozpin and Cinder going off the deep end, screaming at him about "another innocent you threw into the way of harm to protect yourself" that triggers the exposition where we find out about her origin and motives.
