#this got a little rambly
The writers of 15x19 and 15x20 were so single-mindedly focused on killing Dean that they disregardedandoverturned anything that could have stood in the way of getting the conclusion they wanted, and here’s how you can tell:
FIRSTthe SPN writers depowered God–the BIG BAD–in the episode BEFORE the finale. they just took him out. super easy, barely an inconvenience. why?
Because they had to de-power God in order for Dean to die because we all know Chuck never would have let that happen (maybe to Sam but certainly not to Dean)
BUTthey couldn’t just let God be defeated, because they set up all those Horrible Consequences™ of the world going out of balance and stuff
Of course Jack was the logical choice to replace Chuck as the new god at the end of 15x19
BUTJack loves Sam & Dean AND Cas, he would neverallow bad things to happen to his fathers, he literally woke Cas up from the Empty because Dean was sad, he brought Sam back from death, he would want the three of them to live their lives out in peace and happiness TOGETHER
Suddenly the writers have written themselves back to square one: with a god that won’t kill Dean
So what do they do?
The SPN writers had to figure out a way to removeJack from the story in order for Dean to die so they came up with some contrived “I’m gonna be hands off” nonsense and let him poof away and just assumed that one line would be enough to explain his absence at Dean’s demise
Then they spent 25 MINUTES on a Dean’s Perfect Day ™ experience – monsters and vamp!mimes and pie – like they were worried we wouldn’t feel enough when they killed him, like we were in some kind of K-Drama world.
And then they killed Dean.
That was their big master plan. That was the ONLY THING they accomplished in the last episode. And they didn’t even make it good.
He didn’t even die how he wanted, guns blazing, knives swinging, throat ripped out, a Hunter’s Death. He died because someone else made that barn. He had no freedom in life and none in his own death.
Dean’s death was especially pathetic because the writers never understood Dean. He talked a big talk about wanting to die on a hunt, because that was all he thought he DESERVED. That was the fate he ASSUMED was coming. That was CHUCK’S FATE FOR HIM. That was the fate he imagined for himself based on 40 years of Chuck pulling every single string in his life. Dean didn’t know he could want something else, and he was just finally getting around to figuring out how much morehe deserved. And they killed him.
And that’s why they killed him.
Because Dean Winchester was on the verge of figuring out he deserved more than Supernatural. That there was more to him than what the gods of his show would allow. That he deserved happiness, and being, and saying, and LIFE.
And the writers couldn’t let that happen.
Because they needed Dean to die.
That was the only way they could win.
