Something I keep remembering-and-forgetting to post about Varis...
Back in 4.5 we were theorising about him possibly being possessed by Emet, especially in the second half of the meeting. During that scene when we start to press him about the Ascians, he exclaims something like "now you're starting to ask the right questions!".... and then Emet himself says the same thing or close to it, I think when we were looking at the murals.
Someone also suggested at some point that from the previous zodiac associations, Emet is linked with Gemini and there might be potentially two of him?
But then that doesn't really seem to tie in with how it ended.
