Well, it started with her curse warning her about a party of Osirian adventurers presumably dispatched by Osirion to kidnap the cake girl. In the sense of sending her to the key location with a cake to be delivered about fifty minutes later.
Then Pilar's curse told her she shouldn't just turn the kidnappers over to Security because that would make her curse sad, and her curse claimed that giving her the information was an act of trust in Pilar's Lawfulness and she needed to act like a god or her curse wouldn't be trusting her again.
So Pilar went to the Grand High Priestess's office to submit herself to the authority of somebody who understood deranged Chaotic Good curses invoking implied god-agreements. But the Grand High Priestess was not there. And when she was contacted by mirror, the person she put in charge of Pilar was Pilar.
Pilar had to run a meeting. It involved a lot of intelligence officers debating what to make Osirion believe. They were much older and more powerful than her and Pilar had to act like she was an invincible Project Lawful girl who was totally able to run meetings like that. There were lots of decisions about what was best for Project Lawful and Carissa Sevar was completely out of contact and the Grand High Priestess had put Pilar in charge and Pilar had to guess what Sevar would've wanted her to have done.
