Dropping the Act by jadztone
Sherlock and John are quite happy living together with Rosie in Baker St. They might be even happier if they didn’t act towards each other like their love is only platonic. Mycroft brings troubling news in the form of Mary’s parents wanting to know just what their grandchild’s home life is like. The boys decide to spend Christmas pretending like they are in love in order to seem more like a "normal" family. It's easy enough to pretend when all you're doing is dropping the act.
The night before they travel to Dorset to spend Christmas with Sherlock's parents and John's wife, 221 Baker Street is peaceful with the smell of baking, flickering candles and presents under the tree. But Father Christmas can't be relied upon to bring the boys their heart's desires. Just as well Mrs Hudson - who is NOT a fairy godmother OR their housekeeper, thank you very much - is so good at her job.
Untitled Christmas Goose Game by meansgirl (Mystrade)
Greg should have known better than to say the phrase ‘I’ll owe you one,’ to Sherlock Holmes. This was his own fault, really. After four years, he really ought to have learned by now. But Greg had been tired and desperate and Sherlock had been acting like a stroppy child. The words had slipped out and then Greg had immediately forgotten them.
In which Greg agrees to pose as Sherlock's boyfriend at Christmas, finally meets the invisible Mycroft Holmes, catches feelings, and has a very happy holiday indeed.
I wish you a very happy Christmas!
