First, THANK you for doing this site. It's an amazing resource right now. Second, maybe someone has already said this, but if not, wanted to know what people thought about the fake 221B screens used at Mount Stuart Square. The framed blue skull guy looks the same on those screens as in the Czech trailer. And if that's a connection, the Wiggins actor was on set/nearby that day. I wonder if he could have played a role in administering whatever is causing this nightmarish trip...
I talked a little bit about the new painting (is it even a painting? or is it actually just a picture? I’m thinking the latter) here back in August when Ben Caron gave us a photo of it. I agree that the one in the Czech trailer looks like it’s probably the same one from Mount Stuart Square.
However, you can also clearly see the walls and more of the furniture and decor than is present in the Mount Stuart Square pics, so I at least wouldn’t say that this is that same scene, though they’re quite possibly connected. I think it’s pretty likely that this version of the blue skull is present throughout TLD. Now, why it’s been changed is a different matter, and I honestly don’t have an answer for that. (I’m sure we’ll find out soon enough though.)
As for Wiggins, Sherlock tells us in HLV that taking care of drugged people is more or less his day job, so I personally would put my money on Wiggins being there to look after him rather than being one of the ones to help drug him. But, as always, anything is possible...
