I'm sorry. I'm slow but I am DEAD. You probably already noticed this BUT. "...I'm afraid I cannot congratulate you on your choice of companion *sad smile*... Actually now I can." HE WAS TALKING ABOUT HIMSELF. HE'S THE "BAD COMPANION" *gross sobbing*
YES ACTUALLY I HAVE NOTICED IT. I can’t believe you MADE me watch this AGAIN with my own two eyes, and then make a pretty and sad photo edit of it. YOU MADE ME DO IT. HOW DARE.
(seriously, though, this is literally one of the saddest parts of this episode, because Sherlock pauses for about 3 seconds as if he’s pondering what he has said, and then he came to the conclusion that yes, he is an unsavoury companion indeed).
