Huh. Honestly, that's not something I've actually ever seen elsewhere. Yet. Though when the idea hit me, it was a sorta-"That explains EVERYTHING!!" moment which I'm not too egotistical to deny couldn't hit other people as well.

Definitely seen other people using the same pheromones fanwank as I did to explain away The Girl In Question after all...

And now, I really, really want to read Supergirl/Oracle, because it's not a pairing that I've even thought of before, let alone could see working. I am officially intrigued.
