A: Schooling
Avery began his career as a medic as a student. But not as the kind of student that his parents had imagined. Or, at least, not the kind that they had realized already walked among them.
Avery learned, to his surprise, that the new learning methods his parents speculated about were old, as memories were written directly into his brain. Or perhaps it might have been better to call them instincts. Each set of materials had to be practiced, with matching memories created and embedded into his own memory library before they truly became active. But once they were set, they remained synched somehow with the original data.
Avery gradually came to realize that it was a bit like a simplified version of his own Memory library sorting. The memory inserts were like discard pieces, until they were picked up and sort of... mentally dusted off.
