What would have happened had all of the Huns not survived the avalanche?

I thought of several possible outcomes, based on the premise that Мулан is abandoned after having her true gender uncovered:

(1) Chi-Fu & the rest of the army decide to simply sweep Мулан under the rug and not mention her to the Emperor. In this case, if the Emperor rewards them with any tangible items, some of them may decide to (possibly secretly) give them to Мулан after receiving them.

(2) Someone (most likely Chi-Fu) decides to tell the Emperor about Mulan, and the Emperor decides to summon her to the palace and honor her for her actions.

(3) Мулан (and possibly other members of her family) is summoned to the palace, but to receive punishment instead of honor for her actions.

Which of these do Ты think would be most likely?
