AP: Realizing you might be the villain in the story (also, stumbling into a potential character arc)

So, I've been playing a solo game of Trollbabe, experimenting with various things in a search to take more of that "writing exercise" edge off it.*

However, what prompted me to write this bite sized AP is that the latest scene I played was probably the most immersive solo experience I've had so far, and probably the only time in my roleplaying career (social or otherwise) where a potential player character arc has manifested itself without any planning or engineering on my part.
