Green and Something Else

Hi everyone!

I'm trying to find a completed fanfic I read a while ago on AO3 from the Sherlock (BBC) fandom. I only remember one specific scene, but I do remember the pairings were Sherlock Holmes/John Watson and Mycroft Holmes/Greg Lestrade (so Johnlock and Mystrade).

The scene I recall happens near the end of the fic (or in one of the final chapters):

There’s a tense moment where Mycroft and Lestrade are in a surveillance/control room, watching the enemy — someone they've been trying to catch. At some point, Mycroft gets a call from the enemy who threatens Greg, which causes Mycroft to immediately order his soldiers to storm the place and arrest the enemy without hesitation.

The catch is: Sherlock and John were meeting the enemy inside that location not long before the raid, and it’s unclear if they’ll manage to escape in time or if they’ll be arrested too. Mycroft clearly prioritizes Lestrade’s safety over everything, even Sherlock’s.

I can't remember the title or much else, but I remember it was well-written, in English, and finished. If anyone recognizes it, I’d be so grateful! Thanks in advance!
