“Am I dying?” Trevelyan asked, more curious than concerned.

Aww, it’s cute that he’s more curious and Sherlock’s more annoyed than actually worried.

I also like the details about the Holmes home life that you’ve included, like their insomnia rules, Trevelyan’s lazy eye, the little game Mummy and Mycroft play to trick Sherlock into eating, Father’s ciphers, and the Legos! Everyone has his or her part to play to help the household run (relatively) smoothly, even in such a crisis.

This verse is wonderful.
