Descent Into Darkness Season 2 Episode 5

"At some point throughout this acidic exchange, I experienced a horrific flash of lucidity and came to the realization that the dream was in fact a memory of something that had happened, the words I had said, the secrets I revealed, secrets not just mine own, but those of my colleagues and the task that we’ve been given. And now I was to stew in the revelation of that event, and learn, for good or ill, what had happened." - Johann Muller, June 13th, 1921
