Mycroft had to do a good bit of dirty work when starting in the government. For some reason, he ended up in Afghanistan meeting with various regiments for a job his superiors swore was necessary.
John doesn’t think he’s ever seen anyone wear a suit as well as this ginger-James-Bond bloke. Especially not in a desert.

Much to John’s dismay, Mr. Holmes leaves just as quickly as he arrived, but when, years later, he encounters the name Holmes again, he decides that maybe he will go see the lunatic’s flat after all.

problematic-just-because:

It’s so hard to ship Johncroft when all the fics are either about John rebounding after Reichenbach or Mycroft, for some undisclosed reason, “stealing” John from Sherlock. I’m here for John and Mycroft, not Sherlock.

I mean, instead of focusing on Sherlock being miserable, why not contemplate John falling hard in the warehouse, Mycroft’s absence at the wedding, or the grand saga to precede the realisation that Mycroft is freaking amazing with Rosie?
