>What, if anything, he'll learn though is anybody's guess.
Authen is a real mystery box type character. He has a background in neurology, culture, and classical language, and we've just learned that he was paying house visits to Desmond. He could pull on and even connect any number of the major strings we have hanging right now. Unfortunately, he also has severe dementia, which means any info we get from him is going to be disjointed at best.
Additionally, something that no one has really touched on is that Donovan did not want Melinda near Authen. >>281535328 If you interpret Donovan as being secretly benevolent or at least still loving his family, this paints Authen as dangerous. If you don't, it begs the question of why Donovan suddenly found Melinda visiting with Authen unacceptable, especially when it seems like he was okay with it before.
