Maybe this question is better in the 'thesetison' sideblog, but what are you theories on the line of nurses in the trailer. Someone mentioned it's probably from the mind palace because of how it looks, but if so, why is Sherlock (presumably) imagining nurses? Especially when the voice-over is talking about inner demons waiting during that moment.
Let me start by saying that I definitely would not pair the voiceover with what’s being shown on screen at the time. Trailers are built for drama and excitement, and not logic, so we honestly have no way of knowing if that voiceover is actually connected with that scene or not. (And my money would be on it not being directly connected.)
But let’s talk about the nurses. From setlock, we can seem to connect the scenes filmed at Riverside House (which is where that shot of the nurses comes from) with those filmed at Mount Stuart Square. In both locations, we have a conference-style table with people sitting around it attached to IVs, with Culverton Smith there seemingly presiding over whatever’s going on. It looks like it’s essentially the same scene happening in two different places. Now the fact that the scene at Mount Stuart Square is taking place in the middle of the street makes me think that it certainly isn’t really happening that way, so then I feel like the scene at Riverside House is likely the “real” version of the scene.
Now I see a couple options here for this “real” scene. It could be that Sherlock is actually there for whatever weird things are happening there (and we do know that Ben was spotted outside Riverside House their second night there, even though Sue told us he wasn’t filming). OR it could be that someone is telling him about what happened and he is visualizing it, kind of like the scene of Emelia on the balcony in TAB. Either way, I feel like whatever is happening with the nurses at Riverside House is real, not something that Sherlock has hallucinated or otherwise completely made-up in his head.
But then we have it repeated in the middle of the street at Mount Stuart Square, and that I feel has to be some kind of mind palace-type scene. (Conference tables don’t just appear in the street, right?) It could be a deduction--that Sherlock has suddenly figured out something about the real scene from Riverside House--and is picturing it in the middle of the street as he makes his deductions. But given his poor condition during the other filming we saw at Mount Stuart Square and the fact that there was a scene where he was standing in front of a taxi, seemingly oblivious to the fact that he’s in the middle of the street, I don’t think it’s quite as simple as a deduction scene. (I will say that the other scenes at Mount Stuart Square don’t have to connect, but as there weren’t really any costume changes, Sherlock is behaving similarly sick throughout all of it, and the location would be quite obviously the same throughout these scenes, it makes sense that they would be connected.) So my thoughts on how it all fits together are that Sherlock witnesses whatever happens with the nurses at Riverside House (or is told by a client perhaps about what happened there--but I lean toward him having actually seen it). Then later when he’s sick, he stops in the middle of traffic at Mount Stuart Square because he’s hallucinating/flashing back to what happened at Riverside House.
Wow, ok, that was a long explanation for essentially a two sentence summary of what I think is going on, but hopefully you can kind of see where my thoughts are coming from there. I should also say that we of course know very little about these scenes in the first place, so there could be pieces missing that would make all of this make more sense, but based on what we’ve got, this is what I’m thinking right now. Ask me again in a month and maybe that will have changed, lol.
