John killed for him, offered to die for him, given up his relationships with other people for him, forgiven him for shit like drugging and terrorising him as an experiment, and made sure he didn’t smoke or take drugs and stayed with him on danger nights and never ever for a second doubted him even when everyone else did and completely fell apart without him like to the point where he was just drinking on his couch all day and his friends were treating him like he’d lost his spouse and that shit when on for two fucking years and then when he came back he forgave him so fucking easily and he shaved for him and he barely demanded an apology and then even when Sherlock manipulated him and mocked him about the bomb he laughed he fucking LAUGHED and called him a cock and was like ah, bruh, come here and give us a kiss, and he literally FELT HIM UP on his stag night and cried when Sherlock said how much he loved him and jumped up in the middle of his fucking wedding shouting WHAT DO I DO and brought his gun on Christmas just because Sherlock asked him to and believed Sherlock would know what to do because Sherlock ALWAYS knows what to do in John’s eyes and looked like his entire goddamned world was crashing down around his ears when Sherlock shot Magnussen and was so traumatised and miserable
on the tarmac that he could barely speak. That’s how in love with Sherlock Holmes John Watson is.
