I am pretty sure she can leave school when the world is about to be destroyed, though I don't think Reyna would want to miss the war and also if Annabeth comes CHB dosen't have a leader, though then again the romans are alot more serious about that thing.

Also The Doors of Death may be where the final battle will take place. So the whole army will fight there to take them back though ultimately the 7 might close them and that will be them answering the call.

And now that i think about it the Chiron thing makes sense
