Another thing... Right at the end of that trippy sequence where Sherlock walks on the walls of 221b, he falls on the sofa and I'm pretty sure that his face is clean-shaven. (I would add a screenshot but I'm on mobile) Is it some kind of glitch in his mind palace/drugged perception of the world, like when in TAB John was suddenly wearing 21st century clothes?
Hi Lovely!
So here’s our poor Sherlock during his trip-out, stubble and soft face and all:
And here he is at the end of the sequence:
Which certainly looks like he’s clean-shaven; let’s take a closer look:
While it’s difficult to tell, I’m wont to say that Sherlock is NOT clean shaven here. You can see hints of his five-o’clock shadow around his chin, and you can see hints of stubble above his lips.
So, in my opinion, no, I don’t think he’s clean-shaven, and it’s not a glitch in his perception. Given the already tripped out state of his mind, I don’t think it would alter out his stubble. There was a narrative reason for modern!John and for bits of reality filtering in – there’s no narrative reason for chin stubble disappearing :P
