john can't handle all the sherlock

Imagine Sherlock and John on a case in a karaoke bar and Sherlock needs to get a clearer view so he decides to just sing a song and he puts it on random and it’s “I Will Always Love You”. So he starts singing the first few lines:

If I should stay, I would only be in your way
So I’ll go, but I know
I’ll think of you every step of the way
And I will always love you

and he looks at John and they’re both covering up smiles because it’s so cheesy and un-Sherlock-y. As the song goes on, however, Sherlock’s small smile fades with the revelation of the lyrics, and he’s still looking at John but now he just looks sad and John’s smile also fades with the realisation of what Sherlock is actually saying, let alone directing at him:

Bittersweet memories
That is all I’m taking with me
So, goodbye
Please, don’t cry
We both know I’m not what you, you need

and on that last line, Sherlock’s eyes even start tearing up slightly because he’s finally saying what he means and letting it out and John sees it, too. Once the song ends, Sherlock rushes offstage and John doesn’t follow him, because they both know that what just happened carries more weight than any other words they’ve ever traded.

Like in that scene where Sherlock literally looks like a kicked puppy while standing with Mary and looking at John and Sholto….he does his tiny little sigh and looks down at the ground the way he does when he is heartbroken and he literally looks like he’s going to cry….

Is he even jealous in a romantic sense? like they made him say “ex” instead of “former” to add a romantic connotation (though as a purest I don’t even think of John and Sholto beyond a mirror for John and Sherlock I’m just a baby I can’t) but I don’t even think Sherlock is jealous in a romantic sense….like I’m not saying he absolutely can’t be cognizant of John’s bisexuality but in this instance….

It’s almost like “great the only place I had in his life was the sort of cranky and exciting and unsociable person and he secretly loves that and now I’m not even that…he talks about Sholto all the time and not me…he is the most important person in my life in every and any category and while I may be his ‘best friend’…what do I even mean to him…what do I provide…what category do I even win if not this one”
