It's been a decade or so since I read the Wheel of Time books, but a few things stuck with me (sort of, really not sure about the details anymore): Male mages go insane if they use their magic, unless they wear a control collar - which their handler can use to not only support them while they use magic, but also to control them and inflict horrible pain on them.
Basically, all I want is Reese wearing one of those collars for Finch (consensually or not, at least at first), and Finch only ever using it to help and protect him, never abusing his power or hurting John like he could, and like John expects he will.
(Maybe John escaped from the CIA when they found out about his talent and tried to put a collar on him, or maybe Kara or Snow was his handler for a while, and fucked him up pretty badly, and he's well on his way to insanity by the time Finch finds him on the streets. Or maybe Finch finds him at a slave market for mages and realizes his talents are too valuable to be wasted?)
