tip: "sherlock (tv)" m/m NOT "sherlock holmes/john watson"
I totally agree with onstraysod and couldn't have expressed it better. They were husbands in the show? Best headcanon EVER!(Also, your writing is wonderful!)
Oh, thank you so much! And, yes, I think the theory that they were married the whole time makes their interactions so much sweeter (and sadder!). Now I can't think about them looking for each other after Carnivale or the medical tent scene the same way again... :)
