The Depiction of Dean Winchester’s Intelligence - Part 1
Dean has often been called the brawn to Sam’s brains - even by himself. There is no doubt that he thinks he’s a stupid grunt.
However, he’s far more intelligent than he and those who choose to overlook the signs believe. Contrary to popular belief, I think his portrayal in earlier seasons does not make him look dumb next to Sam. His intelligence might not be the same as his brother’s - that is, he’s more practical and less of a bookworm - but Dean is far from the stupid macho man he’s seen as too often.
This list contains by no means every proof of Dean’s intelligence that has ever been shown in the series, but I still hope to point out a pattern.
