He looks so beautiful at the wedding. It breaks my heart.
You can see the exact moment that Sherlock’s brain catches up with the fact that John has just held him close, and is now slowly stroking a hand down his back.
Look at that second last gif. John says, “Can you wait ‘til I sit down?”
And Sherlock’s all, “Oh yeah, sur…” (ohhh… *internally dying*).
Like that wee little widening of his eyes in that last gif, just before he looks down a little! Look at that, and look at what John’s arm is doing while he’s making those looks!
Notice too, how neither of them can meet one another’s gaze after that hug. John pulls away and doesn’t even look at Sherlock, and then when he finally turns his head, Sherlock looks away.
And John’s face in that last gif, too. As his hand reaches the small of Sherlock’s back and drops away, he knows. He just knows, and it’s too damn late.
