Summary: After Sherlock's plane lands.
A/N: Written for Come at Once: Round 4. kizzia's beautiful, evocative prompt, 'Faithful in Adversity', insisted that I think of John. From there, my brain went in an unexpected direction.

Excerpt: “You aren’t really in a position to make ultimatums, Doctor Watson,” Mycroft said.
“Apparently I am, because I’m making one."
