a question - spoiler warnings
If you haven't seen episode 1 of season 3, don't read on. It's not a big spoiler, but, well, there it is.

I just saw that episode. At the end, Molly comes in with her fiance Tom. Sherlock gives him a weird look. A moment later, John says 'did you say something?' Sherlock: 'no.' John: 'probably for the best.'
What did I miss? Why the weird look, and what is there to say, and why better not said? I didn't recognize Tom from before, but then, I'm not too observant.
Or is it NOT something I missed, but something that'll be explained in the future?
Thanks for any replies, especially helpful ones. 😁
