i'm not sure that he's figured Amy out just yet... i'm not sure that the crack had as much to do with his wanting Amy to come along as i originally thought, at least, at the very best he only seems to remember/have it in mind a small portion of the time. But perhaps he is very, very good at hiding what he's actually thinking/knows. He has freely admitted to hiding things from Amy, which is unusual for him. My brain is just teeming with ideas atm, though, and nothing has quite settled yet. But i'm sure you know where my ideas lie... and i did some major squeeing round about the time where he said that she had to remember.
