Thank you for reading and leaving your thoughts. :)

I think the personality contrasts you point out are also what makes Sam and Dean so complimentary. In fact, "complimentary" is a dyadic structure used to describe a kind of spousal relationship dynamic. LOL. Anyway, that's beyond the point ... but just think how tiring and uninteresting it would be if Sam and Dean had virtually the same personality? Variety is the spice of life!
