Sherlock has been gone for a year now, and John is finally moving on. That all changes when he and Molly go to dinner one night. Post-TRF but season three hasn't happened. This is my take on Sherlock coming back. Sherlolly eventually not John/Molly

One night when she walking home from work, Mary runs into none other than the Doctor! He whisks her off to protect her from aliens on earth that are trying to get to her. This is only the beginning for the two. 10/OC
