I don't like how this scene was depicted in anime, they cut corners too much. Its like she talking to empty space, rally in the wrong state. Here, on the other hand, we Can see the audience. Reminded "Black Panther" final fight, how extras been killed then rise to try again.
I'm not sure I can even say she's bullshitting. Because that usually implies that you are intentionally lying your way through things. She's just sort of stumbling around and people just miraculously fill in all the holes for her through interpretation or additional comments.
In her defense, she knows there's a conspiracy. She's just not sure how to explain it without "I died, and this exact setup is what killed me". Thankfully that one spy defied orders and sent the truth to the prince's attendant.
