I find it so hard to believe that Holmes would really let Watson believe he was dead for 3 years because even though he often doesn’t understand how his actions affect others emotionally, he’s definitely smart/empathetic enough to understand how much that would hurt Watson. And I also think he trusts Watson too much to believe that he couldn’t keep the secret of Holmes being alive.
My personal headcanon is that after Reichenbach, Holmes found a way to let Watson know that he was still alive, that he wouldn’t be back for some time, and that Watson needed to keep up the lie that Holmes was dead in order to keep them both safe. Which is honestly just as deliciously angsty to me as the idea that Watson actually thought he was dead for 3 years.
Imagine 3 years of Watson having to grieve a man he knew was still alive. His loved ones comforting him and him not being able to tell them that the reason he suffering so much wasn’t because he knew Holmes was dead, but because he spent every day worrying about his safety. Knowing that the love of his life is out there facing danger without him there to protect him, and meanwhile all he can do is wait breathlessly until the next time Holmes can manage to send him a message to let him know he’s okay. Knowing that at any moment, Holmes might be dying somewhere, and he might never know where or when or how.
Maybe he told Mary, because honestly I get the impression that she’s incredibly good at keeping secrets. Maybe it just came out one night while she was holding him after he broke down sobbing in their sitting room. I think she’d be angry at Holmes at first for causing her husband so much pain, but after Watson explains the whole story, she’d understand. The next time he got a coded note from one of the irregulars with an update from Holmes, he immediately runs to tell her. She’s so relieved to see such happiness on his face, even if it secretly breaks her heart. But it’s alright, in the end. She’s always known that Watson’s heart had never truly belonged to her. Their marriage is practical, almost fraternal, and that’s okay. What they have together is enough. She hopes that one day she can meet someone that she’ll love with the same ferocity that Watson loves Holmes, and she knows that if that day comes, her husband will be more than understanding.
And then Mary gets sick. It’s clear that she’s going to die. And all she can think about is how cruel it is that the two people Watson loves most should be taken from him.
“That man of yours had better come back to you soon,” she says in the weak voice of someone in their final days. “If he doesn’t, I swear that my ghost shall haunt him until he drags himself back to London and apologizes to you in person.”
Startled, Watson laughs. Mary smiles. It’s the first laugh she’s heard from him in weeks.
And then Mary dies, and the one person that Watson could have leaned on for support as he grieved is still lost. And now there is no one else who knows that Holmes is alive, or that Watson spends every waking hour waiting for him.
I do think the part about him fainting when Holmes comes back is true, though. Not from shock, but from pure relief.
Anyway I can’t stop thinking about this sooooo I guess I’m gonna have to write a fic about it. Goddamnit.
