do you guys ever think about how john literally groomed sam and dean to be the perfect lucifer vessel and michael sword without ever realising he was doing it. it would make him want to fucking die and yet he does it so perfectly. instils it into sam that he has no autonomy, no control over his life, unconsciously lets him know there is something Wrong about him. instils it into dean that his personhood is in hunting, that that’s how he’s useful and how he can be loved. and none of that’s intentional except maybe sam’s disempowerment. but it still happens.
dean was john’s sword long before he knew he’d be michael’s sword. and sam was john’s, full stop, long before he knew he’d be lucifer’s.
