B would have to hear the detail from A (probably through A complaining?) which is completely plausible. Another option is that C comes into the picture and drops the detail bomb as a threat/one upsmanship thing, which is in character for them.
There are ways to impart the detail (it's key to the drama of the story and it's what will eventually need to be resolved so that A/B and C can be happy) that are fine, but having it introducted from A's POV would feel a lot more natural. It's something that if I were doing a fic/kink meme fill I would mentioned upfront in the authors notes so that I didn't have to hash it out.
I suppose I could do one POV shift really early on to A's POV in order to reveal the detail if I don't like how it comes to light from B's? I really don't want to, but the option is always there, righr? :/
