When has Sherlock not treated Molly like she’s brilliant? Honestly, he seems to hold her in very high esteem, all things considered.
I’m not even talking about the “you always counted” scene. I’m just talking about their regular interactions together. While Sherlock must have enough contact with Stamford at Barts to have a conversation about flatmates, Molly Hooper is the ONLY person we regularly see him interact with at the hospital. Is this because he likes to exploit her crush on him? No, because Sherlock wasn’t even aware of it until “Scandal”.
