like a married couple (ao3)
what if mycroft was a meddler and also john and sherlock have kind of been acting like a married couple since the day they met and what if one day when mycroft stops by he dares to explicitly say something about what he thinks their relationship is only to find that he's wrong. but him being wrong is actually just him being right in a new and more annoying way. and also there's a cute little mystrade moment at the end. 4.3k. rated teen. mostly fun domestic fluff. (and a tiny dash of stress. but mostly fluff.)
everyone say thank you to elena @ohwatson for getting me to bring this out of my drafts folder and also for encouraging the little mystrade-centric ending!
