I wonder how exactly feeding on love is scientifically possible? I assume that Changelings feed off of the releases of dopamine, adrenaline and oxytocin that the brain gives off whenever one forms an emotional connection to something/somewhere/someone, but it'd be cool to find out exactly how it works.Or maybe that's just me. I don't really know how other people think.
It works the same way as magic. You can't explain it, but the process looks really neat!
