The few times that we are given a glimpse of the possibility of love in Holmes’s heart, it is generally in relation to Watson. People can interpret this as platonic, but if people are going to take the line “It was not that he felt any emotion akin to love for Irene Adler” and make Irene Adler into a love interest anyway, I don’t see what’s wrong with taking a closer look at these lines:
“It was worth a wound—it was worth many wounds—to know the depth of loyalty and love which lay behind that cold mask.”;
“Quick, man, if you love me!”; and
“’You know,’ I answered with some emotion, for I have never seen so much of Holmes’s heart before, ‘that it is my greatest joy and privilege to help you.’”
Seems funny that Holmes and Watson can say the word love in relation to eachother multple times and it gets bromance’d across the board, that Watson can tell Holmes that it is his “greatest joy and privilege” to help Holmes but seeing that comment as anything but platonic is just slash shippers being obsessive, and meanwhile a woman who Holmes met once, barely spoke to, and specifically doesn’t love becomes the love interest for the next 100+ years. Yikes.
