Has anyone noticed how Seymour's Character Theme/another version of it plays at ~21:50 in the audio drama?

I hope that means what I think. Main villain themes always come in Final Fantasy only when they are connected to the Main Villain.

Hopefully it is time for a real final battle with the main antagonist who succeeded in what he wanted:
