"a touch of pink" just make me think of "a touch of cloth" which is that parody of a crime drama with anna chancellor and others
and one of the recurring jokes is the male lead moaning about the fact he’s in love with the female lead but she’s gay (which he assumes because she had a female partner) and she’s like “No, Jack, bi” and he’s like “Bye, Anne..” and dramatically walks away despite the fact she actually returns his feelings
and I’m like imagining the same with Sherlock and John
'John, you're straight.' 'Bi, Sherlock.' 'No don't go, I'm sorry, it's none of my business'
THE SHERLOCK PILOT WAS ORIGINALLY CALLED A TOUCH OF PINK??????????????
