A/N: believe it or not, I was monologuing in the shower and this just happened.
I have an arch-nemesis, he mused with some sick humor. The laugh bubbled unbidden from his throat, squeezed off at the last second in an attempt to avoid the inappropriate reaction.
Normal people don't have arch-anything, but then Dean's life was so far from anything remotely considered normal that he'd dismissed the word entirely.
In all honesty, Dean should have seen this coming. He was an avid comic book fan, after all.
It was always the same. Two beings of significance, no matter what the circumstance, BEST FRIENDS- never just the guy down the street that hates you for no fucking reason- have a majorly dramatic breakup. One person always does something that just pushes the other to this climax, this precipice from which there is no return. Words are said that can never be taken back, blows exchanged, and the once inseparable duo are wrenched apart, to forever dance around each other, but never able to finish the other off. It happened to Magneto and Professor X, Batman and the Red Hood, shit, it even happened to those guys from The Social Network.
Dean figured it was just on a whole other level, becoming an enemy of an Angel of the Lord.
