ooh, thanks for bringing this back. in the notes, yan-yae mentions the idea that sherlock had particular places to hide depending on who he wanted teso find him, so maybe look into the metaphorical readings on those connections too.
and as always any mention of glass says glass closet to me, and the orangery is such a perfect example. was there a single person present for that best man speech who didn’t pick up on sherlock’s Big Secret?
reviewing the lists of locations in the op, they are each a range of sites, from underground to way up high (stairs code by @just-sort-of-happened ) private to public, if that matters. interesting that only some of them seem to exist in our world, i wonder if any of the ones that don’t are references to other adaptations in the Giant Lego Set Of Canon ™. i love that camden lock is all about controlling the flow of water=emotions! and the giant clock face, after TAB, we associate the pocket watch with the modern phone=heart.
testing whether there is a matching between the two lists, just in case that twigs anything.
the underground, and leinster gardens
the courtroom, and dagmar court?
baker st, and molly’s bedroom (since molly is a john mirror, and there’s that indication in ASIB that both boys were up in john’s room)
mycroft’s bunker, and parliament hill?
roland kerr college and the padded cell don’t immediately suggest connections (to me) to any of the others, camden lock, the greenhouse, or big ben… i would be interested in anyone else’s thoughts!
