#'sam has committed the horrible offense of being mean to dean. this means he hates his brother and thinks him inferior.'

[quietwingsinthesky]

that's why i'm always like :/ when the great crime of 'sam is rude to dean sometimes' is brought up like. idk, it reads to me as A) siblings are Like That And It's Literally Fine and B) that the stuff sam says glances off of dean cause he also Gets It, that sometimes sam's mouth runs ahead of his filter, that sam feels comfortable enough with dean that he is letting go of that rigid hold he usually keeps on it and being a bitch about things. and what counts to dean is never sam teasing him or being mean, what counts is what sam does, that he is gonna have dean's back when it counts.
