Sorry, dunno how many sh&co enjoyers watch D20, but… in the event that John does leave 221b for Mary my brain cannot help but draw a parallel between Sherlock and Riz Gukgak (beyond both of them being detectives lol).
Manic and overjoyed seeking of knowledge. Cutting your hands on shards of glass in relentless pursuit of the truth (revenge). Loving your friends in a way that it feels like it is impossible for them to reciprocate. Ruthlessness as a means of protecting what means the most to you. The loneliness in intellect to extremely eager companionship pipeline. God just… everything about the confrontation with Baron in FHSY.
“You would not have lied so frivolously. You love the truth. You seek it so much that you cut your hands upon the inside of crystals. But you use deception to protect yourself from something you fear.”
“The years will go by, and everyone will find someone who matters more to them than you.”
Ouch!
