At long last Sherlock and John are getting married.
Much to everybody's surprise he enlists both Mycroft and Lestrade as his groomsmen (Harry and Clara had nabbed John the second the announcement was made).
Nobody expected Sherlock to be such a difficult groom to manage though - determined as he is for everything to be perfect.
Through their joint suffering acting as the balm between a legitimately stressed out Sherlock and the rest of the world, Mycroft and Lestrade slowly grow closer
tl;dr Sherlock and John get married, and Mycroft and Lestrade and Sherlock's groomsmen - they grow closer together during the run up to the wedding
