Summary
What if the Moriarty family were not unknown to the British Government? What if Mycroft found out?
Am I the only person that thought they heard Moriarty mention the IRB in Young Sherlock and then can’t for the life of me find the scene again? Or was it all a dream within a dream?

The Other Doctor by ThatOneTwoThree

Summary
At a country house party, Sherlock, James and Mycroft meet a sexy Presbyterian doctor. For Sherlock it’s lust at first sight. For James, it’s dinner and a show. For Mycroft… it’s business as usual, digging his little brother out of his very own brand of trouble.
Very ooc - in the multiverse of my brain, there is a slutty, slutty version of Sherlock who never met a pair of strong forearms he didn’t like. James - tragically underused here - is along for the ride, since Drag Race isn’t on in 1871. Plus, Mycroft will be DAMNED if he doesn’t get his brother married to a nice man who is good for him…
And I know that it is awash with anachronisms in terms of terminology…

Summary
Inspired by the draft design images of Loki in Ancient Egypt.
Fiddling with time, Loki visits Ancient Egypt and is mistaken for a new god.
Sometime later, he revisits, but discovers he has miscalculated his timing, landing in the modern day and startling an Egyptologist. He may also have set off some wards placed in the temple but its original owners. Whoops. How does one avoid the wrath of ancient gods? Have you tried charm and thinly sliced meat?
