I love that Anna and Bates finally talked about Green's murder, and that he had NOT done it. Still, it's odd that Anna went to Picadilly, to the exact spot...do you think it's possible that she did it, possibly in a 'blanked out' kind of state, and has no recollection of it? There is the fact that someone heard Green say, 'Why have you come?'. Anna of course is smaller, but if he was right on the curb, and surprised, it's possible. Also, a connection to a 60's movie, Midnight Lace - someone is stalking and trying to kill Doris Day's character, in London. The first attempt is when she is nearly killed by being pushed while waiting for a bus.
