What? Oh HELLS no. Just... no. If this is really true and what's happening, then I genuinely could not be more disappointed. Another evil companion? No, that absolutely sucks, I hate it. And I feel more visceral frustration and anger about it than I ever imagined feeling about the final reveal. I thought at most I'd be mildly disappointed that the final origin wouldn't be from a short race but this? This feels like a slap in the face to anyone who wants genuinely heroic companions and they stick us with what appears to be the most overtly villanous and evil companion yet.
Hey, Gray Ghost, if you ever need a truly good companion, I am always there for you!
