That is an interesting ending. But I really doubt if Percy would like her getting involved in a catfight with Reyna. After all his fight is against Octavian and not the crazy legion. Besides Annabeth is way more experienced than Reyna and would be much better after coming from Tartarus.

Now imagine Piper and Reyna fighting each other. I would certainly burst out laughing throughout the entire scene.
