When running an encounter, is our character ICly supposed to be in that scene?

I recently ran an encounter with the prompt:
A demon from hell has become interested in your target, they decide to see if they can tempt them into becoming one of their instruments on earth.

When emoting, I did not need to use @me so I simply puppeted a demonic NPC. My character isn’t a demon so I don’t know how I would’ve logically had my character in that scene. But, I was codedly transported from my bedroom to the other character’s bedroom when the scene started, even though I’d never met that character and it was an opposing society base.

Asking on newbie, there were conflicting opinions on whether, as with plots, our characters are supposed to be running the encounter.

Some clarity on this from Nova, and maybe also some rewrites of the prompts if our characters are meant to participate, would be appreciate. (E.g., something like: “A demon from hell has become interested in your target, your character must try to dissuade them from giving in to temptation”).
