The placement of lyrics during the final scene of The Sign of Three is absolutely masterful. I mean just look at it.
John turns to his wife after learning she is pregnant:
You know I didn’t even know her name.
John and Sherlock lock eyes and smile at each other:
Hypnotizing, mesmerizing me.
Sherlock watches John and Mary dance away from him:
I felt a rush like a rolling bolt of thunder. Spinning my head around and taking my body under.
Sherlock turns his back on all of his friends, realizing he’s the only one left alone:
As I recall it ended much too soon.
Sherlock carefully places the song he composed for John and Mary within an envelope as he prepares to leave:
Why’d it take so long to see the light?
