AVClub: The context isn’t romantic; their conversation about Morland’s cruelty and Sherlock’s struggle with addiction is the opposite of pillow talk. But the image is deliberate. He’s low to the ground, offering the ring to a standing Joan, and that framing is deeply recognizable regardless of context—it’s an offer. It’s an offer here, too, though not of marriage: marriage is a product of passion. It’s something even rarer for Sherlock: an offer of intimacy.
