So, I went and poked at AO3, and found more Daemon AU fics (this might be a new obsession - if it is, I blame you. ;) )

And I'm honestly wondering just how much it would totally frak with everyone else's heads if their daemons were to switch (in a manner of speaking) and tend to gravitate towards the other half of the pair. Not that they'd trade daemons or forms, or who they were connected to, but playing with the idea that they hold each other sacred and close and the daemons making a deliberate, tangible show of it.
