]It seems overly observant. Surely it could have also been a clever way to get Anne out of his sight. But Anne never suspects this. I'm uncomfortable with her powers of observation. They seem almost superhuman.

If Anne and CW were strangers, then Anne probably were too good in her observation. But remember, once upon a time, they were everything to each other - something like "soulmates". I don't think it is surprising that Anne should be able to tell what CW was thinking. It simply proves that their acquaintance was not skin-deep.
