No, I wasn't possessed. Had I been caught, however, we know enough about what the shadows do to people and how they react when caught that I could have replicated it well enough.

I would apologize, but I do not think I was very subtle with my intent. Perhaps I would have reconsidered when I found myself awake, but when I found him in the bar, he was drinking Death After Noon - a Mondstadt wine, and one Kaeya drank often, like he was sulking there.
