I have a feeling that the oath part will have something to do with Chiron keeping an oath and dying. I love the character of Chiron but if he's wounded, but because he can't die until he's not needed anymore, a new teacher (say Percy maybe) steps up to let him rest. That would be a twist that no body would see coming.
