So have they interacted before? If so, they would already know what the other is, would they not?

Yes, they have. Michael has been to the bookstore multiple times in order to search for a book that could help him cure his amnesia, but never had any luck. They should know what the other is just by looking at them, because the aura I mentioned before will have a faint, but visible glow when they look at each other.
