You can understand the Queen’s predicament. The easiest answer for her would be to change the laws so she could pick which daughter she wants to be queen after her, but there would be some public outcry about it. Both for changing traditions, and also likely some ponies would not feel the streaming influencer Pipp Petals would be as good of queen as her elder sister, Zipp.
So you advise the queen to use the page to change the laws, a power she already has. But the page will let her do it without drawing a lot of public attention. Sure it’s cheating the system, just a little, but she obviously cares for her daughters and wants to be able make them happy, and making it a choice instead of a tradition seems the right route.
You see the queen smile, obviously delighted for someone to say and agree with her feelings. She gently tucks the page back under her wing. “Thank you, and I’m sorry to ask you for advice out of the blue. Ponies can get bent out of shape when things change. I should know, I was so stubborn when it came to my girls and their quest for the Unity Crystals. But change is good sometimes, but if I can make that change go over more smoothly, I think everyone will be happier.
“So thank you.” The queen bows her head to you gently, and you return the same. You linger to share a few final words with the queen before you have to get back to your job. As you depart, you think about what you’ve just done and… you probably feel okay about it. Changing an old stupid law that ponies would only gripe about because it was old and “tradition” seemed like a good use for the page.
