User blog:Tommy,Klaus&Kol2012+/What abandoned ideas were there in the 14 seasons of supernatural?

Not counting the two spin offs, were there any abandoned ideas over the shows run that were said but never came to be?, i started watching in season 6 and even back then, i wasnt privy to all that i know now with the internet or the supernatural magazine

eric kripke named an idea lately in the pilot he thought was stupid regarding the impala, i cannot remember what it was, but he said they got rid of it
