But Mycroft is appearing in Sherlock’s mind palace in that scene. So does that mean Sherlock is making the connection as well? Or does he feel like Lestrade is a brother - and is similar to Mycroft?
Wear this tie. Rupert: but didn't you literally just wear this in. Wear it. Wear the tie, Rupert. I ship it. Ian's chill, I've kissed a guy on TV before.
