Codependence works both ways
Is it just my perception or are the fans who bemoan the brotherly codependence almost exclusively Dean fans or a few Sam fans? I just don’t think I see it much in the bi-bro fans.
There seems to be a notion that it is Dean who makes the bad decisions that lead to situations like the one they are in now, and that the “codependence” is always a bad thing. Not true.
Dean chose to sell his soul to bring Sam back and that led to breaking the first seal. Sam chose the path of revenge and that led to breaking the last seal. But they were both determined to kill Lilith, so either way, that last seal would have broken.
It was that “codependence” that led to Stull Cemetery. If Dean hadn’t gone — a suicide mission but Dean wouldn’t let Sam do it alone — then Sam wouldn’t have found the strength to overcome Lucifer because ultimately he did it to save Dean even if his original intention was to save the world. Dean risked himself, literally died, to get Death to retrieve Sam’s soul in S6, so he could have his brother back, and Sam risked his own sanity — “I won’t leave my brother out there alone” — to be at Dean’s side when Godstiel appeared.
Sam took on the trials to prevent Dean from going on a suicide mission, but when Dean asked him to stay with him, Sam gave up closing the gates of Hell … for Dean. And in 9.01, he was ready to die, he’d given up, given in, but when Dean offered him a chance, he stayed for Dean.
This season may be a redemption arc for Dean, but ultimately it will be the boys together who will pull everyone’s bacon out of the fire. That’s how it works, and if fans want the codependence to end, things will go very, very badly for the boys and the world.
