At this point, either the writers and Kripke in SPN have absolutely no communication with their casting personnel or they've just stuck their heads in the sandpit, singing "lalalalalalala."
Seriously, SPN is one character away from earning their own racefail shit storm if it's not coming down the pipe already.
I still want to throttle Ruby, smack Sam upside his head and place him inside a Devil's Trap, daring him to step out. I don't want to do anything to Dean 'cause at this juncture - there's no way anyone can damage him any further.
C'mon, man, Krip-keeper, you can do better than this...
