Originally planned to use this as reference for art, but the quality of my screenshots is just too bad to draw from it.
I loved that they made the effort to underline how difficult the wedding was for Sherlock, he can be seen stimming quite a lot throughout the episode and his body language speaks volumes.
Oh @ceruleanmindpalace ! You are SO right about this. I had not noticed this particular sequence so bless you for slowing it down (and us) to notice the stimming.
