Watching the show Lucifer, I just found out that another name for Lucifer is Samael. I did some research, and this is actually based on some real mythology, and not purely from the show. Do you think this is why Sam was named Sam? As foreshadowing to his connection with the Devil?

mittensmorgul:

Sam Winchester is called Sam because Kripke originally based him on Sal Paradise, a character in On The Road based on Jack Kerouac himself. But Kripke didn’t want to call him Sal, so he changed it to Sam.

(Dean is based on Dean Moriarty from On The Road, who is in turn based on Neal Cassady)

And yeah, Lucifer’s original name was Samael (depending on the version of the story, there’s multiple reasons he was also or subsequently called Lucifer). 

Kripke’s original intent for the series, which he continued to repeat throughout the first several seasons of the show, was that angels were never something he intended to include in the Supernatural mythology. That only changed after s3.

So no, I don’t think Sam being named Sam had anything to do with Lucifer. It is convenient in hindsight though. 🙂

(Also, John Winchester was originally intended to be named “Jack”– presumably after Kerouac– but there was already a real person named Jack Winchester living in Kansas at the time and they had to change it for legal reasons. And the original family name from the first drafts of the script was “Harrison” which just sounds all kinds of wrong now. But in my AU version of the Supernatural movie Dean was acting in in The Exception to Every Rule, I borrowed the surname Harrison for his character. :P)
