TD12 & Mary
I was rewatching TLD and I don’t recall this being talked about. When Sherlock is in hospital we can see this scene
OH LOOK, The damn serum is glowing, by it’s own apparently! As you can see the bed light can’t hit the serum, or at least can’t hit it in a way it would glow like that. And there is no light source behind or beneath, you can even see how it’s glowing by the shadow on the ceiling.
And of course it reminded me to
Yes! TD12. Then I remembered how some people have talked about Mary possibly injecting the TD12 when Sherlock was again in hospital in HLV, so I searched for the scene. I didn’t recall if we could see the serum or not in that scene and I found this
The damn serum in the foreground and iluminated with a light like the TD12 just before Mary appears.
Also it makes me thing about the glowing skull as some people have already pointed.
