Yeah, I'm really enjoying this too, to a distracting degree. (Obviously, since I'm writing *volumes* here :P). But yeah, I can definitely see what you're saying and your fanon makes sense.

Unfortunately for me, I just tend to be *annoyed* by anything that doesn't allow for there to be wincest going on. Boys, stop fighting and being distant! Dean, stop banging girls and pushing Sam to do so! Evil things, leave the boys alone, so they can doooooooo it!!!!

Heh. But that's my illness. I've nicknamed it Denial. ;)
