YES!! How great was it that Sherlock was interviewing the wedding guests and screening them for John's protection? It's clear there is nothing he won't do to protect John, which he reiterated with his "last vow". I'm just totally on eggshells about how he's going to end up having to keep that vow next week. I know it's going to be bad, probably worse than we are all imagining. My one wish is that the season ends with the two of them together, at least, and not separated on some cliffhanger again. I had enough of that last season!
Not to rain on your parade. But the writers of the series said that the cliffhanger in season 3 would be even worse than the season 2 one.
Also, I've listened on the soundtrack from S3E3, and almost all of the tracks are sad one, which probably means that the episode will be pretty heart breaking
