Reasons Why Sherlolly Is Life.
Molly is the only person who Sherlock apologises to:
He doesn’t stop the slap, when a boxer doesn’t defend himself it tells you the same thing as when an assassin doesn’t shoot straight - they’re not really trying…
Molly is the only one who makes Sherlock look sad:
Takes Molly on a “Sherlock” date, they solve crimes together and Molly :"Had a lovely day".
She’s the only one to ever make him awkward or stutter:
He never remembers Greg’s name, but he remembers Tom’s. Never before did he hold back a hurtful deduction then here:
Molly is the only one who Sherlock doesn’t think is an idiot, and she’s the only one ever to read him, to break him down to a human being.
Then, of course there’s this: When Sherlock needed someone, more then he’s ever needed anyone in his life, when he thinks he’s going to die, who does he turn to? When he’s shot by his best friend’s wife, who saves him? What does he need? No, he doesn’t need anything from her, because he simply need her. Molly. His Molly. His pathologist.
Queen of his mind palace.
"So, she becomes one of the very small select band of people that he absolutely trusts. And he adores Molly, of course he does. He loves her"
