sam vs cas (colette/abel debate)

reinewinchester:

(this will be brief)

okay so i don’t think that castiel is relevant in this at all. i don’t think that cas represents anything that parallels with cain’s story line. i also don’t think that the sam/abel, dean/cain thing is as cut and dried either. 

the sam/abel parallels are clear. to cain, it seems inevitable that dean will eventually kill sam, because that’s his fate, because it was cain’s. however, it’s quite arguable that sam is also dean’s colette. sam is his anchor and his saving grace. how many times have we seen sam save dean so far? just this season? the answer is a lot. sam’s relationship with dean is mirrored in both cain/abel and cain/colette.

but there is one flaw with both these parallels. sam is not just dean’s abel or dean’s colette, he’s dean’s sam. and that’s the difference between dean and cain. cain had an abel and he had a colette, but cain never had a sam.
