You are very thinky, productively so for me, so thank you. I definitely need to rewatch, since I think I dozed through parts on first watch. From all the eps and parts of this one I *have* seen, I agree with your surmises and/or conclusions, now that you mention it.

And also, you have given me food for thought for *days*--I had a minor brain-go-splodey contemplating a Sherlock-Lightman meeting. As I said, thinky.
