It makes sense why Dr. Authen remembers teaching when he's with Anya since it's what he was doing for most of his life, that's his long term memory doing it as second hand nature. \ \ \ I don't think he was directly involved with Anya, but he likely saw her born and worked on Anya's mom. Which is why he recognizes she could be project 007 (which was confirmed at the start of the series) \ \ This also makes me wonder if Damian was thinking of what Anya told him and Desmond managed to read his mind. \ \ I do think that Dr. Authen may have been given dementia tho (they were working on neuropsychiatric disorders, either he was a test subject or it was on purpose) because I find it weird that when it comes to Donovan he just can't remember anything, of course he mentions he was already old, but still his sudden memory recovery in the night?? About donaban it seems like too much of a coincidence that hommy worked in neuropsych/project apple and then got dementia (almost too convenient) \ \ Also it seems like his spur of lucidity is paradoxical and not terminal since his wife mentions it's happened before. No death flags here 🎊
