The proposal
We never got to see John and Mary’s wedding, or even the proposal. We did get to see Sherlock’s (wedding) vow to John, and from the first time I watched this scene it has looked like a proposal to me. The nervous question, the shocked reaction, the happiness of knowing that you’re the most important person in the life of the person that matters most to you… The Sign of Three is a true blessing.
let’s not forget their position, John looking like he’s down on one knee and looking up at him with Sherlock looking down???
It’s a proposal. The audience is definitely meant to see it that way.
